BODY VERIFICATION TEST – VER 1

Diagnostic Test

Perform Body Verification Test

NOTE: If the SKREEM or PCM/ECM was replaced, refer to the service information for proper programming
procedures.

1. Disconnect all jumper wires and reconnect all previously disconnected components and connectors.

2. Ensure that all accessories are turned off.

3. Ensure that the battery is fully charged.

4. Turn the ignition on.

5. With the scan tool, record and erase DTC’s from all modules.

6. If an electronic control module was replaced, select the applicable module from the scan tool menu and press
“Misc. Functions”. If the module has programmable features, program as necessary.

7. (Export only) If the Intrusion Transceiver Module (ITM) and/or Siren was replaced, select ITM from the scan
tool ECU View menu then “Misc. Functions” and perform the applicable replacement procedure.

8. Turn the ignition off, wait 10 seconds, and then turn the ignition on.

9. Operate all functions of the system that caused the original concern.

10. With the scan tool, select ECU View and check for DTC’s in the modules.

Are DTCs present in any of the modules or is the original condition still present?

Yes

>> The repair is not complete. Refer to the related category for the DTC or symptom that is still present.

STANDARD PROCEDURE

PCM/ECM/SKREEM PROGRAMMING

NOTE: Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM), be certain to
check the related component/circuit integrity for failures not detected due to a double fault in the circuit.
Most PCM/ECM driver/control circuit failures are caused by internal component failures (i.e. relays and sole-
noids) and shorted circuits (i.e. pull-ups, drivers, and switched circuits). These failures are difficult to detect
when a double fault has occurred and only one DTC has been set.

When a PCM, or ECM, and the Sentry Key REmote Entry Module (SKREEM) on vehicles equipped with the Sentry
Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:

1. Program the new PCM or ECM.

2. Program the new SKREEM (also sometimes referred to as the Wireless Control Module or WCM).

3. Replace all ignition keys and program them into the new SKREEM/WCM.

PROGRAMMING THE SKREEM

The SKIS Secret Key is an ID code that is unique to each SKREEM/WCM. This code is programmed and stored in
the SKREEM/WCM, the PCM/ECM, and each ignition key transponder chip. When the PCM or SKREEM/WCM is
replaced, it is necessary to program the Secret Key into the new module using a diagnostic scan tool. Follow the
programming steps outlined in the diagnostic scan tool for “PCM Replaced” or “WCM Replaced” under “Miscella-
neous Functions” for the “WCM/Wireless Control Module” menu item as appropriate.

NOTE: If the PCM/ECM and the SKREEM/WCM are replaced at the same time, all vehicle ignition keys will
need to be replaced and new keys programmed into the new SKREEM/WCM.

NOTE: Programming the PCM/ECM or SKREEM is done using a diagnostic scan tool and a PIN to enter
secure access mode. If eight attempts are made to enter secure access mode using an incorrect PIN,
secure access mode will be locked out for one hour. To exit this lockout mode, turn the ignition to the RUN
position for one hour then enter the correct PIN. (Ensure all accessories are turned OFF. Also monitor the
battery state and connect a battery charger if necessary).

PROGRAMMING IGNITION KEYS TO THE SKREEM

Each ignition key transponder also has a unique ID code that is assigned at the time the key is manufactured.
When a key is programmed into the SKREEM/WCM, the transponder ID code is learned by the module and the
transponder acquires the unique Secret Key ID code from the SKREEM/WCM. To program ignition keys into the
SKREEM/WCM, follow the programming steps outlined in the diagnostic scan tool for PROGRAM IGNITION KEYS
OR KEY FOBS under MISCELLANEOUS FUNCTIONS for the WCM/WIRELESS CONTROL MODULE menu item.

NOTE: A maximum of eight keys can be learned to each SKREEM. Once a key is learned to a SKREEM, that
key has acquired the Secret Key for that SKREEM and cannot be transferred to any other SKREEM or vehi-
cle.

If ignition key programming is unsuccessful, the scan tool will display one of the following error messages:

•

Programming Not Attempted - The scan tool attempts to read the programmed key status and there are no
keys programmed into SKREEM memory.

•

Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKREEM is unable to program an
ignition key transponder due to one of the following:

− The ignition key transponder is faulty.
− The ignition key transponder is or has been already programmed to another vehicle.

•

8 Keys Already Learned, Programming Not Done - The SKREEM transponder ID memory is full.

•

Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock cylinder is
already programmed into SKREEM memory.

MODULE-ANTILOCK BRAKE

DESCRIPTION

The Antilock Brake Module (ABM) is a microprocessor-based device which monitors the antilock brake system
(ABS) during normal braking and controls it when the vehicle is in an ABS stop or when in a traction control situ-
ation. The ABM utilizes a 47-way electrical connector on the vehicle wiring harness. The power source for the ABM
is through the ignition switch in the RUN or ON position.

The ABM (1) is mounted to the HCU (2) as part of the
Integrated Control Unit (ICU). The ICU is located in
the engine compartment on the inboard side of the
right body frame rail behind the strut tower. For infor-
mation on the ICU, (Refer to 5 - BRAKES/HYDRAU-
LIC/MECHANICAL/ICU

(INTEGRATED

CONTROL

UNIT) - DESCRIPTION).

OPERATION

The primary functions of the Antilock Brake Module (ABM) are to:

•

Monitor the Antilock Brake System (ABS) and Electronic Stability Program (ESP) for proper operation.

•

Detect wheel locking or wheel slipping tendencies by monitoring the speed of all four wheels of the vehicle.

•

Control fluid modulation to the wheel brakes while the system is in ABS or traction control mode.

•

Modulates fluid pressure to the wheel brakes to control vehicle yaw rate in ESP mode.

•

Store diagnostic information.

•

Provide communication to the scan tool while in diagnostic mode.

•

Illuminate the amber ABS indicator in the instrument cluster.

•

Illuminate the yellow ESP/BAS indicator in the instrument cluster (if equipped).

The ABM constantly monitors the ABS and ESP (if equipped) for proper operation. If the ABM detects a fault, it will
turn on the amber ABS and yellow ESP/BAS indicators and disable the ABS or ESP if so equipped. The normal
base braking system will remain operational at that time.

The ABM continuously monitors the speed of each wheel through the signals generated by the wheel speed sensors
to determine if any wheel is beginning to lock. When a wheel locking tendency is detected, the ABM commands the
ABM solenoid coils to actuate. The coils then open and close the valves in the HCU that modulate brake fluid
pressure in some or all of the hydraulic circuits. The ABM continues to control pressure in individual hydraulic cir-
cuits until a locking tendency is no longer present.

REMOVAL

Due to packaging and limited space it is necessary to remove and disassemble the Integrated Control Unit (ICU) to
service the Antilock Brake Module (ABM) on this vehicle. (Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/ICU
(INTEGRATED CONTROL UNIT) - REMOVAL)
