Normal Operation

NOTE: If the backup transceiver or the Remote Function Actuator (RFA) module fails, or any of the related circuitry between the 2 components fails, one or more of these DTCs may set.






This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Backup transceiver
- Intelligent Access (IA) key battery
- RFA module



PINPOINT TEST M: DTC B10D9:11, 12, 31 OR 87

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

- Is the resistance less than 5 ohms?

Yes
GO to M5.

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

-------------------------------------------------
M5 CHECK THE BACKUP TRANSCEIVER CIRCUIT FOR A SHORT TO GROUND


- Measure the resistance between the backup transceiver C3371-3, 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 BACKUP TRANSCEIVER CIRCUIT FOR AN OPEN


- Measure the resistance between the RFA module C2153b-15, circuit VPK32 (WH/BU), harness side and the backup transceiver C3371-3, 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 FOR A SHORT TO GROUND


- Connect: Backup Transceiver C3371.
- 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 BACKUP TRANSCEIVER CIRCUIT 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 C3371.
- 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 FOR AN OPEN


- Disconnect: Backup Transceiver C3371.
