DIAGNOSIS AND TESTING
Module Configuration
Principles of Operation
Some modules must be programmed as part of the repair procedure. If this procedure is not followed
the module will not function correctly and may set a number of DTCs, including B2477 or P1639, which
indicate that some necessary data has not been programmed into the module.
Modules that need programming should not be exchanged between vehicles. In most cases the
parameter values or settings are unique to that vehicle, and if not set correctly will cause concerns or
faults.
Some programmable parameters, such as belt minder on/off, can be changed from the factory setting
at the customer's request.
WDS will automatically attempt to retrieve the module configuration information from all modules, and
from a backup location in the powertrain control module (PCM) when vehicle ID is carried out. If the
module and the PCM do not contain correct information the diagnostic tool will either request "As Built"
data or display a list of items that you will need to manually configure. The diagnostic tool will program
the module based on the data you enter.
There are three different methods that are used for module programming:
zprogrammable module installation (PMI)
z calibration update
z programmable parameters
Some modules do not support all three methods.
Programmable Module Installation (PMI)
The programmable module installation (PMI) method is used when a new programmable module is
installed on the vehicle. It is no longer necessary to command the diagnostic tool to gather module
option content from the old module. The diagnostic tool automatically obtains any available module
option content information from the old module during the vehicle ID routine that runs when the
diagnostic tool is initially connected to the vehicle. It is important that you connect WDS to the vehicle
and allow it to identify the vehicle and obtain configuration data prior to removing any modules. Calibration Update SECTION 418-

NOTE:
Large metallic objects, electronic debit transponder devices or a second key on the same
key ring as the PATS ignition key may cause vehicle starting problems and record DTCs under
certain conditions. If a fault cannot be identified, examine the customer's key for such objects or
devices. If present, inform the customer that they need to keep these objects from touching the
PATS ignition key while starting the engine. These objects and devices cannot damage the
PATS ignition key, but can cause a momentary problem if they are too close to the key during
engine start. If a problem occurs, turn ignition OFF and restart the engine with all other objects
on the key ring held away from the ignition key. Check to ensure the encoded ignition key used
by the customer is an approved Ford encoded ignition key (encoded ignition keys from Rotunda,

GENERAL PROCEDURES
Security Access —
Procedure
NOTE: The security access procedure is utilized to obtain passive anti- theft system (PATS) security
access. PATS security access must be granted to erase ignition keys, enable/disable the spare key
programming switch or perform parameter resets for the instrument cluster. The security access
procedure invokes an inherent 10 minute time delay prior to granting security access during which
diagnostic tool must remain connected to the vehicle. Once security access has been granted, a
security access command menu is displayed that offers various command options (refer to PATS
Configuration Command Index).
NOTE: Select only the commands required by the appropriate pinpoint test.
1. From diagnostic tool: Using the Ford Service Function (FSF) card, select the appropriate instrument cluster. Enter SECURITY ACCESS PROCEDURE. This procedure will take 10
minutes to perform, during which the ignition switch must be in RUN and the diagnostic tool
must be connected to the vehicle.
2. After the 10- minute security access procedure has been completed, a new menu will be
displayed with command options. Select only those functions required before exiting out of this
menu. Once exited out of this menu, the security access procedure must be performed again to
perform additional commands.

current and historical DTCs through the DLC, using a scan tool. If the air bag indicator does not
function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible
chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air
bag indicator require repair.
LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority
will be displayed. After that fault has been corrected, the next highest priority fault will be displayed.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the
air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag
sensors determine that deployment is required. The backup power supply will deplete its stored energy
approximately one minute after the battery ground cable is disconnected.
Electrical System
The electrical system that supports the air bag supplemental restraint system (SRS):
zis powered from the battery through the ignition circuit.
z provides the electrical path from the restraints control module (RCM) to the air bag modules.
z provides the electrical path from the RCM to the air bag indicator.
z provides the electrical path from the RCM to the data link connector (DLC).
z provides the electrical path from the RCM to the generic electronic module (GEM).
Sensor WARNING: The restraints control module (RCM) orientation is critical for proper system
operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been
involved in a collision in which the center tunnel area has been damaged, inspect the mounting
and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags
have deployed. In addition, make sure the area of the RCM mounting is restored to its original
condition.
The SRS contains two sensors which are integral to the RCM. The RCM is mounted on the center
tunnel under the instrument panel. Klj . 3 ba

Most air bag supplemental restraint system (SRS) diagnostic procedures will require the use of the
deactivation and reactivation procedures in this section.
The deactivation and reactivation require the installation and removal of restraint system diagnostic
tools. These procedures require removal of driver air bag module, and the disconnection of the
passenger air bag module. This reduces the risk of deployment of air bag modules and safety belt
pretensioners while diagnostics are being carried out.
Restraint system diagnostic tools are required to carry out diagnosis and testing of the supplemental
restraint system (SRS). It is not acceptable to short-circuit the air bag module connections with a
jumper wire. If a jumper wire is used to short- circuit the air bag module connections, a lamp fault code
(LFC) will be displayed.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
The reactivation procedure requires the removal of any restraint system diagnostic tools installed and
the reconnection of any air bag modules disconnected.
Deactivation Procedure
WARNING: If the supplemental restraint system (SRS) is being serviced, the system must
be deactivated and restraint system diagnostic tools must be installed. Refer to Air Bag Supplemental Restraint System (SRS) in this section.
The air bag restraint system diagnostic tools must be removed and the air bag modules
reconnected when the system is reactivated to avoid non- deployment in a collision, resulting in
possible personal injury.
NOTE: Diagnostics or repairs are not to be performed on a seat equipped with a seat side air bag with
the seat in the vehicle. Prior to attempting to diagnose or repair a seat concern when equipped with a
seat side air bag, the seat must be removed from the vehicle and the restraint system diagnostic tools
must be installed in the seat side air bag electrical connectors. The restraint system diagnostic
tools must be removed prior to operating the vehicle over the road.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: After diagnosing or repairing a seat system, the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the
customer.
1. WARNING: To avoid accidental deployment and possible personal injury, the
backup power supply must be depleted before repairing or replacing any front or side air
bag supplemental restraint system (SRS) components and before servicing, replacing,
adjusting or striking components near the front or side air bag sensors, such as doors,
instrument panel, console, door latches, strikers, seats and hood latches.
Please refer to the appropriate vehicle shop manual to determine location of the front air
bag sensors.
The side air bag sensors are located at or near the base of the B- pillar. Klj . 2 ba

DIAGNOSIS AND TESTING
Diagnostic Instructions —
Air Bag Supplemental Restraint
System (SRS)
The symptom chart can be used to help locate the air bag supplemental restraint system (SRS)
concerns if no diagnostic trouble codes (DTCs) are retrieved and the listed symptoms are observed.
Whether or not the listed symptoms are observed, always perform the following.
1. Retrieve all DTCs stored in the restraints control module (RCM) memory. Refer to Retrieve/Clear Continuous DTCs in this section.
2. Run the On- Demand Self Test to determine what DTCs are currently being sensed by the
restraints control module (RCM) (14B321). Refer to On- Demand Self Test in this section.
3. If the stored DTCs are different than the current DTCs, always repair the current DTCs first.
4. If memory displays different continuous DTCs than the On- Demand Self-Test, perform in the
following order:
z On- Demand Self- Test.
z Memory (Retrieve/Clear Continuous DTCs).
A DTC can indicate several concerns. The DTCs are to assist in system diagnosis and are not to be
considered definitive. Always refer to the pinpoint test corresponding to the DTC to determine where
the concern lies and to repair the concern correctly.
The SRS diagnostics can be divided into three sections.
zDiagnostic test modes
z PID/data monitor and record
z Active command modes
Diagnostic Test Modes
Two menu options are available under the diagnostic test modes.

Retrieve/Clear Continuous DTCs
During vehicle operation, the restraints control module (RCM) will detect and store both intermittent
and hard fault DTCs in nonvolatile memory. The DTC strategy employed by the RCM incorporates a
time-out scheme for determining when a concern exists in the system. This requires a concern to exist
for up to one minute in the system before the RCM will detect it. For the RCM to determine that a
concern no longer exists, the concern must be absent for up to one minute. The actual detection time-
outs vary with each DTC. The DTCs can be retrieved with a scan tool. Any DTCs stored in the RCM
will be displayed on the scan tool along with a brief description of the DTC. If no DTCs are present, the
scan tool will display a SYSTEM PASSED message. This option can also be used to clear DTCs from
the RCM memory, as long as the concern no longer exists. Once 128 key cycles have been recorded
since the concern was last detected, the DTC will automatically be removed from memory.
To retrieve or clear DTCs, follow these steps.
1. Connect the scan tool to the data link connector (DLC).
2. Turn the ignition switch to the RUN position.
3. Follow manufacturer's instructions for the scan tool being used.
4. All continuous DTCs will be displayed. Before proceeding with the clearing operation, make note of the DTCs displayed because, once cleared, they cannot be retrieved.
5. The scan tool will retrieve DTCs again after clearing DTCs and, if any remain, they will be displayed. Hard DTCs will be redisplayed after clearing DTCs since they cannot be cleared from
the RCM.
On- Demand Self Test
The On- Demand Self Test option is used to verify that no electrical concerns exist with the air bag
supplemental restraint system (SRS). Upon entering the self test, the restraints control module (RCM)
will make an electrical check of each electrical component in the system. If a concern is detected, a
DTC is displayed on the scan tool with a brief description of the DTC. Concerns detected during the
self test are not stored in memory, unless the same concern was also detected during normal vehicle
operation. The self test should always be run after any repair to verify that the repair was successful.
To run the On- Demand Self Test, follow these steps:
6. Connect a scan tool to the data link connector (DLC).
7. Turn the ignition switch to the RUN position.
8. Follow manufacturer's instructions for the scan tool being used.
9. The RCM will run the On- Demand Self Test and display on- demand DTCs (reflecting hard
system concerns) on the screen.
PID/Data Monitor and Record
The PID/Data Monitor and Record option allows the scan tool operator to read the state of several
parameter IDs (PIDs) to aid in diagnosing the system. PIDs are real time measurements of parameters
such as voltages, resistances, etc., calculated by the restraints control module (RCM) and sent to the
scan tool for display. Many of the PIDs supported by the RCM are calculated periodically and are,
therefore, not true real time readings.
To retrieve PIDs, follow these steps: 1. Connect the scan tool to data link connector (DLC). Klj . 2 ba
