7A2-140 TRANSMISSION CONTROL SYSTEM (JR405E)
• Electrically Erasable Programmable Read OnlyMemory (EEPROM)
This type of memory allows selected portions of
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM,
such as:
- The vehicle identification number (VIN)
- The software/ calibrations identification numbers
- The control module security information
• Flash Read Only Memory-Flash Memory
Flash memory has increased memory storage capacity.
During programming, all information within this type of
memory is erased, and then replaced with entirely new
information.
Service Programming Methods
The two methods of programming a TCM are listed
below:
• Remote Programming
• Pass Thru Programming
For information on programming a TCM using one of
the methods listed above, refer to Service
Programming System (SPS) (Remote Procedure) or
Service Programming System (SPS) (Pass-Thru
Procedure).
Before Programming a Control Module
Important: DO NOT program an existing TCM with the
identical software/ calibration package. This procedure
is not a short cut to correct the driveability condition.
This is an ineffective repair. An TCM should only be
programmed when the following occurs:
• When a service procedure instructs you to replace the TCM.
• An updated software/ calibrations is released.
Ensure that the following conditions are met before
programming a TCM:
• The scan tool PCMCIA card is programmed with the latest software.
• The TIS 2000 is installed with the latest software.
• The hardware key is plugged into the computer port.
• Vehicle system voltage:
- There are no charging system concerns. Allcharging system concerns must be repaired
before programming the TCM.
- The battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully
charged before programming the TCM.
- A battery charger is NOT connected to the vehicles battery. Incorrect system voltage or
voltage fluctuations from a battery charger may
cause programming failure or TCM damage. - Turn OFF or disable any system that may put a
load on the vehicles battery. Turn OFF or
disable systems such as:
◊ Heating, ventilation, and air conditioning
(HVAC) systems
◊ Headlights
◊ Room lights
◊ Accessory equipment
• The ignition switch is in the proper position. The scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of
the ignition switch during the programming
procedure unless instructed to do so.
• All tool connections are secure:
- The RS-232 cable
- The connection at the DLC
- The voltage supply circuits
• DO NOT disturb the tool harnesses while programming. If an interruption occurs during the
programming procedure, programming failure or
TCM damage may occur.
• If you are performing the Pass-Thru programming procedure using a notebook computer without the
power cord, ensure that the internal battery is fully
charged.
Service Programming System (SPS)
(Remote Procedure)
Notice: Some module will not accept SPS remote
procedure using 10MB PCMCIA card. In such case,
use 32MB PCMCIA card or SPS pass-thru procedure.
The Remote SPS method is a three-step process that
involves the following procedures:
1. Connecting the scan tool to the vehicle and obtaining the information from the TCM.
2. Connecting the scan tool to the terminal and downloading a new calibration file from the
terminal into the scan tool memory.
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file into the TCM.
Performing the Remote Procedure 1. Connect a scan tool to the vehicle and obtain the TCM information using the following procedure:
Notice: Ensure the TCM is installed in the vehicle and
the battery is fully charged before programming.
a. Install a scan tool.
b. Turn ON the ignition, with the engine OFF.
c. Select Service Programming System (SPS) > Request Info.

11A-8 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
Diagnostic Information and Procedures
Diagnostic Starting Point - Immobilizer
Controls
Begin the system diagnosis with Diagnostic System
Check - Immobilizer Controls. The Diagnostic System
Check - Immobilizer Controls will provide the following
information:
• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and the their statuses.
The use of the Diagnostic System Check - Immobilizer
Controls will identify the correct procedure for
diagnosing the system and where the procedure is
located.
Diagnostic System Check - Immobilizer
Controls
Description
The Diagnostic System Check - Immobilizer Controls is
an organized approach to identifying a condition that is
created by a malfunction in the electronic immobilizer
control system. The Diagnostic System Check must be
the starting point for any immobilizer system concern.
The Diagnostic System Check directs the service
technician to the next logical step in order to diagnose
the concern. Understanding and correctly using the
diagnostic table reduces diagnostic time, and prevents
the replacement of good parts. Test Description
The numbers below refer to the step numbers on the
diagnostic table.
2. Lack of communication may be because of a partial
or a total malfunction of the serial data circuit.
6. The presence of DTCs which begin with U, indicate
that some other module is not communicating.
9. If there are other modules with DTCs set, refer to the
DTC list. The DTC list directs you to the appropriate
diagnostic procedure.
Important: • DO NOT perform this diagnostic if there is not an immobilizer system concern, unless another
procedure directs you to this diagnostic.
• Before you proceed with diagnosis, search for applicable service bulletins.
• Unless a diagnostic procedure instructs you, DO NOT clear the DTCs.
• Ensure the battery has a full charge.
• Ensure the battery cables (+) (-) are clean and tight.
• Ensure the ICU ground is clean, tight, and in the correct location.
• Ensure the ICU harness connector is clean and correctly connected.
• Ensure the ICU terminals are clean and correctly mating.
• Ensure the immobilizer security information is correctly programmed into the ICU, ECM and PIM.
• Ensure the ICU is correctly installed to the steering lock.
• Ensure objects does not block transponder key in the steering lock.
• Ensure another transponder key is not attached to the key ring.
