-------------------------------------------------
M5 CHECK THE PATS TRANSCEIVER CIRCUIT VPK32 (WH/BU) FOR A SHORT TO GROUND


- Disconnect: RFA Module C2153b.
- Disconnect: Backup Transceiver C2086.
- Measure the resistance between the backup transceiver C2086-3, circuit VPK32 (WH/BU), harness side and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to M6.

No
REPAIR the circuit. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

If DTC B10D9:11, 12, 31 or 87 is retrieved again, GO to M12.

-------------------------------------------------
M6 CHECK THE PATS TRANSCEIVER CIRCUIT VPK32 (WH/BU) FOR AN OPEN


- Measure the resistance between the RFA module C2153b-15, circuit VPK32 (WH/BU), harness side and the backup transceiver C2086-3, circuit VPK32 (WH/BU), harness side.




- Is the resistance less than 5 ohms?

Yes
GO to M7.

No
REPAIR the circuit. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

-------------------------------------------------
M7 CHECK THE BACKUP TRANSCEIVER CIRCUIT RPK32 (YE/GY) FOR A SHORT TO GROUND


- Disconnect: RFA Module C2153b.
- Measure the resistance between the RFA module C2153b-16, circuit RPK32 (YE/GY), harness side and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to M9.

No
GO to M8.

-------------------------------------------------
M8 CHECK THE PATS TRANSCEIVER CIRCUIT RPK32 (YE/GY) FOR A SHORT TO GROUND


NOTE: Replacement of the backup transceiver does not require the PATS IA keys to be programmed into the RFA module again.

- Disconnect: Backup Transceiver C2086.
- Measure the resistance between the RFA module C2153b-16, circuit RPK32 (YE/GY), harness side and ground.




- Is the resistance greater than 10,000 ohms?

Yes
INSTALL a new backup transceiver. REFER to Backup Transceiver Anti-Theft - Passive Anti-Theft System (PATS) - Backup Transceiver. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

No
REPAIR the circuit. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

-------------------------------------------------
M9 CHECK THE BACKUP TRANSCEIVER CIRCUIT RPK32 (YE/GY) FOR AN OPEN


- Disconnect: Backup Transceiver C2086.
- Measure the resistance between the RFA module C2153b-16, circuit RPK32 (YE/GY), harness side and the backup transceiver C2086-4, circuit RPK32 (YE/GY), harness side.




- Is the resistance less than 5 ohms?

Yes
GO to M10.

No
REPAIR the circuit. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

-------------------------------------------------
M10 CHECK THE BACKUP TRANSCEIVER
