Pinpoint Test K : B108A:12
- K1 CHECK THE START/STOP SWITCH 1 (Crk_Fact_B1) PID
- Using a scan tool, view RFA module PIDs.
- Monitor the RFA module PID Crk_Fact_B1 while pressing and releasing the start/stop switch.
Does the PID display YES when the start/stop switch is pressed and NO when the start/stop switch is released?
Yes GO to K5. No GO to K2. - K2 ISOLATE THE START/STOP SWITCH
- Disconnect: Start/stop Switch.
- Monitor the RFA module PID Crk_Fact_B1.
Does the PID change from YES to NO when the start/stop switch is disconnected?
Yes INSTALL a new start/stop switch. REFER to Start/Stop Switch . No GO to K3. - K3 ISOLATE THE BCM
- Disconnect: BCM C2280B.
- Monitor the RFA module PID Crk_Fact_B1.
Does the PID change from YES to NO when the BCM is disconnected?
Yes INSTALL a new BCM. REFER to Multifunction Electronic Modules . No GO to K4. - K4 ISOLATE THE PCM
- Disconnect: PCM C175B (3.7L engine).
- Disconnect: PCM C1381B (2.0L GTDI engine).
- Disconnect: PCM C1551B (3.5L GTDI engine).
- Monitor the RFA module PID Crk_Fact_B1.
Does the PID change from YES to NO when the PCM is disconnected?
Yes INSTALL a new PCM. REFER to Electronic Engine Controls . No REPAIR the circuit CDC35 (BU/WH). - K5 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect and inspect all RFA module 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 RFA module connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK 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 RFA module. REFER to Multifunction Electronic Modules . 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.
