- Ignition ON.
- Using a scan tool, clear the BCM DTCs.
- Using a scan tool, perform the BCM self-test.
Is DTC C113A:11 still present?
Yes GO to E3. No GO to E9. - E3 ISOLATE THE PATS TRANSCEIVER AS THE CAUSE FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: PATS Transceiver C252.
- Ignition ON.
- Using a scan tool, clear the BCM DTCs.
- Using a scan tool, perform the BCM self-test.
Is DTC C113A:11 still present?
Yes GO to E4. No INSTALL a new PATS transceiver. Refer to Passive Anti-Theft System (PATS) Transceiver . - E4 CHECK THE WAKEUP CONTROL OUTPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: BCM C2280F.
- Measure the resistance between the BCM C2280F-5, circuit CE436 (VT/OG), harness side and ground.
Is the resistance greater than 10, 000 ohms?
Yes GO to E10. No REPAIR the circuit. - E5 CHECK THE WAKEUP CONTROL CIRCUIT FOR AN OPEN OR SHORT TO VOLTAGE
- Attempt to start the engine.
Does the engine start?
Yes GO to E7. No GO to E6. - E6 CHECK THE WAKEUP CONTROL CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: PATS Transceiver C252.
- Disconnect: BCM C2280F.
- Measure the resistance between the PATS transceiver C252-1, circuit CE436 (VT/OG), harness side and the BCM C2280F-5, circuit CE436 (VT/OG), harness side.
Is the resistance less than 5 ohms?
Yes GO to E10. No REPAIR the circuit. - E7 ISOLATE THE BCM AS THE CAUSE FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: PATS Transceiver C252.
- Disconnect: BCM C2280F.
- Ignition ON.
- Measure the voltage between the PATS transceiver C252-1, circuit CE436 (VT/OG), harness side and ground.
Is any voltage present?
Yes GO to E8. No GO to E10. - E8 CHECK THE WAKEUP CONTROL OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: PCM C175B (3.5L Ti-VCT) or C1381B (2.0L GTDI or 3.5L GTDI).
- Ignition ON.
- Measure the voltage between the PATS transceiver C252-1, circuit CE436 (VT/OG), harness side and ground.
Is any voltage present?
Yes REPAIR the circuit. No GO to E9. - E9 CHECK FOR CORRECT PCM OPERATION
- Disconnect and inspect all the PCM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the PCM connectors. Make sure they seat correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK On-Line Automotive Service Information System (OASIS) for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new PCM. Refer to Powertrain Control Module (PCM) . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. - E10 CHECK FOR CORRECT BCM OPERATION
