GENERAL INFORMATION
DaimlerChrysler Computer Relearn Procedures
INTRODUCTION
Vehicles equipped with engine or transmission/transaxle
computers may require a computer relearn procedure after the vehicle
battery is disconnected. Vehicle computers memorize and store vehicle
operation patterns for optimum driveability and performance. When the
vehicle battery is disconnected, this memory is lost, resulting in a
driveability problem. Depending on the vehicle and how it is equipped,
the following driveability problems may exist:
* Rough or unstable idle.
* Hesitation or stumble.
* Rich or lean running.
* Poor fuel mileage.
* Harsh or poor transmission/transaxle shift quality.
Default data is used until NEW data from each key start is
stored. As the computer restores its memory from each new key start,
driveability is restored.
Driveability problems may occur during the computer relearn
stage. To accelerate computer relearn process after battery removal
and installation, specified computer relearn procedures should be
performed. See appropriate procedures under specified manufacturer.
COMPUTER RELEARN PROCEDURES
ALL MODELS
NOTE: Read all procedures listed to determine why each procedure is
to be performed before proceeding.
Vehicle Driveability Computer Relearn Procedure
Manufacturer does not provide a specified computer relearn
procedure for obtaining proper driveability. If vehicle battery was
disconnected or Powertrain Control Module (PCM) was replaced, driving
the vehicle will enable the PCM to perform a computer relearn
procedure for obtaining proper driveability. Inform customer that
driveability may differ from what they are accustomed to until the PCM
completes the computer relearn procedure.
NOTE: If Powertrain Control Module (PCM) was replaced, the correct
vehicle mileage and Vehicle Identification Number (VIN) must
be programmed into the PCM to prevent Diagnostic Trouble
Codes (DTCs) from being set in the Anti-Lock Brake System
(ABS) module and Supplemental Restraint System (SRS) module\
.
To program PCM and clear DTCs from ABS and SRS modules,
proceed to appropriate procedure listed. If replacing
Powertrain Control Module (PCM) on models equipped with a
Smart Key Immobilizer Module (SKIM), the secret key data must\
also be updated to enable engine starting. To update secret
key data, proceed to appropriate procedure listed.
Programming PCM & Clearing DTCs From ABS & SRS Modules
Connect scan tool to Data Link Connector (DLC) below driver's\
side of instrument panel. Using scan tool, enter correct VIN and
mileage into PCM. Using scan tool manufacturer's instructions, clear

DTCs from ABS and SRS modules.
Updating Secret Key Data
Connect scan tool to Data Link Connector (DLC) below driver's\
side of instrument panel. Go to ENGINE, then MISC menu on scan tool.
Place the SKIM in SECURED ACCESS MODE by using the appropriate
Personal Identification Number (PIN) for this vehicle. PIN may be
obtained from the owner, vehicle's invoice, or from the manufacturer.
Select UPDATE THE SECRET KEY DATA. The data will be transferred from
Smart Key Immobilizer Module (SKIM) to the PCM.
NOTE: If 3 attempts are made to enter the SECURED ACCESS MODE using
the incorrect Personal Identification Number (PIN), the
SECURED ACCESS MODE will be locked out for one hour. To exit
this locked-out mode, leave ignition switch in the ON
position for one hour with all accessories turned off. It may
be necessary to monitor battery state and connect a battery
charger.
FWD CARS & FWD VANS

DESCRIPTION
The speed (cruise) control system is electronically
controlled and vacuum operated. The electronic control is integrated
into the Powertrain Control Module (PCM). System consists of the
following components: Powertrain Control Module (PCM), servo, speed
control switches, vacuum reservoir, vehicle speed sensor, speed
control relay and brake switch.
System controls are located on each side of steering wheel
air bag module and consist of ON/OFF, SET, RESUME/ACCEL, CANCEL AND
COAST buttons. System is designed to operate at speeds above 30 MPH.
OPERATION
SYSTEM CONTROLS
To Set Speed Control
Press ON/OFF button to turn speed control system on.
Accelerate to desired speed (minimum of 35 MPH) and press SET/COAST
button. Vehicle speed will be maintained.
NOTE: Speed control system will automatically disengage when
vehicle speed decreases to less than 35 MPH or increases to
more than 85 MPH.
To Disengage Speed Control
Press brake pedal. Press clutch pedal (M/T). Press CANCEL
button. Press ON/OFF button. If ON/OFF button is used, set speed will
be erased from memory.
To Resume Previous Speed
If set speed has not been erased from memory and vehicle
speed is more than 35 MPH, press RES/ACCEL button.
To Increase Speed
With speed control system on, increase set speed by rapidly
pressing and releasing RES/ACCEL button. Each pressing of button will
cause speed increase of 2 MPH. For example, pressing button 3 times
will increase speed by 6 MPH. To increase speed gradually, hold
RES/ACCEL button down until desired speed is reached. When button is
released, new set speed will be maintained.
To Decrease Speed
With speed control system on, decrease set speed by pressing

TROUBLE SHOOTING
ROAD TEST
Perform a road test to verify speed control malfunctions.
Ensure speedometer operation is smooth without flutter at all speeds.
Speedometer fluttering may cause surging in speed control system. For
speedometer diagnosis, see appropriate INSTRUMENT PANELS article. If
road test verifies a surge following speed control set and speedometer
operates smoothly, see OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL
SET.
If road test verifies an inoperative system, and speedometer
operates smoothly, check for:
* Diagnostic Trouble Codes (DTCs). See SELF-DIAGNOSTIC
SYSTEM.
* Misadjusted brake switch. See BRAKE SWITCH under REMOVAL &
INSTALLATION.
* Poor electrical connections at servo.
* Leaking vacuum reservoir, check valve, hoses or connections.
See VACUUM SUPPLY under COMPONENT TESTS.
* Secure attachments of S/C servo cable.
* Smooth operation of throttle linkage.
* Defective PCM or wiring.
* Defective servo. See SPEED CONTROL SERVO under COMPONENT
TESTS.
To verify a speed control electronic malfunction, use scan
tool to check for DTCs. See SELF-DIAGNOSTIC SYSTEM. A speed control
malfunction may occur without setting a FTC. If no DTCs are stored, go
to CHECKING SPEED CONTROL OPERATION under SYSTEM TESTS.
OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET
If operator repeatedly presses and releases set button with
their foot off accelerator (lift foot set) to begin speed control
operation, vehicle may accelerate and exceed desired set speed by 5
MPH and then decelerate to less than desired set speed before
achieving desired set speed.
Speed Control (S/C) has as adaptive strategy that compensates\
for variations in S/C cable lengths. When S/C is set with vehicle
