DTC P0643

- 5 Volt Reference 1 Circuit High Voltage

DTC P0652

- 5 Volt Reference 2 Circuit Low Voltage

DTC P0653

- 5 Volt Reference 2 Circuit High Voltage

Circuit/System Description

The drive motor generator power inverter module (PIM) contains two motor control modules (MCM) and a hybrid powertrain control module

(HPCM). Each MCM utilizes a 5 Volt reference power supply for internal circuit needs. This fault is handled inside the PIM and no external

circuits are involved.

Conditions for Running the DTC

* The control module runs the program to detect an internal fault when the key is ON.

* Ignition voltage is 8-18V.

Conditions for Setting the DTC

The control module has detected an internal malfunction.

Action Taken When the DTC Sets

* DTCs P0642, P0643, P0652 and P0653 are Type A DTCs.

* The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays.

Circuit/System Verification

Test for correct operation of the Direction IMS in every range selection. Refer to Typical Scan Tool Data.

If the IMS operation matches the logic table, the system is functioning normally.

Circuit/System Testing

1. Disconnect the transmission X176 24-way connector. Ignition ON. The scan tool Direction IMS parameter should display HIGH for the R1,

R2, D1, D2 and S signal circuit displays.

瀚慖f a signal displays LOW, disconnect the PIM connector X1 and test the circuit for a short to ground.

瀚慖f the circuit tests normal, replace the PIM.

2. Install DT-48493 to the vehicle harness connector X176. Verify that a test lamp illuminates between the direction IMS switch ground circuit

and battery positive.

瀚慖f the test lamp does not illuminate, disconnect PIM connector X1 and test the ground circuit for an open, high resistance or short to

voltage condition.

瀚慖f the circuit tests normal, replace the PIM.

3. Connect a 3-amp fused jumper wire between each Direction IMS signal circuit at DT-48493 and the ground circuit terminal. The scan tool

parameter should display LOW for each signal circuit when grounded.

瀚慖f a scan tool parameter always displays HIGH, disconnect PIM connector X1 and test the circuit for an open, high resistance or short to

voltage condition.

瀚慖f the circuit tests normal, replace the PIM.

4. Disconnect the transmission 16-way X1 connector. Install DT-47825-10 to the vehicle harness. Connect a 3-amp fused jumper wire between

the Starter signal circuit terminal and ground. The scan tool parameter should display LOW when the signal circuit is grounded.

瀚慖f the scan tool parameter always displays HIGH, disconnect PIM connector X1 and test the circuit for an open, high resistance or short to

voltage condition.

瀚慖f the circuit tests normal, replace the PIM.

Important: The remaining diagnostic steps test the internal transmission components and circuits. The automatic transmission fluid

pan assembly must be removed in order to perform the diagnostic tests.

5. Disconnect the IMS connector at the switch.

Important: Connect one end of the DT-48493 to the transmission connector. Use the other end as the terminal testing point.

瀚慣est the direction signal circuits and the ground circuit between the IMS and the transmission 24-way X176 connector for a short to

ground, open, high resistance or short to voltage condition.

Important: Connect one end of the DT-47825-10 to the transmission connector. Use the other end as the terminal testing point.

瀚慣est the Starter signal circuit between the IMS and the transmission 16-way X1 connector for a short to ground, open, high resistance or

short to voltage condition. The TCM is a pass-through of the Starter signal circuit and should be tested as a typical circuit path.

瀚慖f the circuit, including the TCM, tests normal, replace the IMS switch.

DTC Descriptor

DTC B3106 00

- Keyless Entry Data Link

Circuit/System Description

The body control module (BCM) communicates with the remote control door lock receiver through the keyless entry serial data circuits. When any

button on the keyless entry transmitter is pressed, the transmitter sends a signal to the remote control door lock receiver. The remote control door

lock receiver sends a function request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and

performs the appropriate function.

Conditions for Setting the DTC

The transmitter that is sending a signal to the remote control door lock receiver is different from those transmitters stored in the BCM.

Action Taken When the DTC Sets

No action is taken.

Conditions for Clearing the DTC

* A current DTC will clear when the fault is no longer present and the ignition switch is cycled.

* A history DTC will clear after 40 consecutive ignition cycles without a fault present.

DTC Descriptor

DTC B2530 02

- Front Fog Lamps Control Circuit Short to Ground

Diagnostic Fault Information

Circuit/System Description

The front fog lamp relay is supplied with battery voltage at all times. The front fog lamp switch signal circuit is grounded momentarily by pressing

the front fog lamp switch. The body control module (BCM) energizes the front fog lamp relay by applying ground to the front fog lamp relay

control circuit. When the front fog lamp relay is energized, the relay switch contacts close and battery voltage is applied through the front fog lamp

fuse to the front fog lamp supply voltage circuit which illuminates the front fog lamps.
