Pinpoint Test
- RETRIEVE BCM DTCs
- Connect the scan tool.
- Ignition ON.
- Using a scan tool, perform BCM self-test to retrieve DTCs .
- Record any BCM DTCs retrieved.
Is U0100:00 present in the BCM?
- Yes:
- REFER to DIAGNOSTIC ROUTINE K : U0100:00 to diagnose the BCM DTC.
- No:
- GO to 2 .
- CHECK THE LIN COMMUNICATION CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect BCM C2280B.
- Disconnect DC / AC Inverter C3501A.
- Measure:
DC / AC Inverter Ground C3501A Ground Pin Circuit Measurement / Action Pin Circuit 5 VDN01 (BU/WH) - Ground
Is the resistance greater than 10, 000 ohms?
- Yes:
- GO to 3 .
- No:
- REPAIR the circuit.
- CHECK THE LIN COMMUNICATION CIRCUIT FOR AN OPEN
- Measure:
DC / AC Inverter BCM C3501A C2280B Pin Circuit Measurement / Action Pin Circuit 5 VDN01 (BU/WH) 52 VDN01 (BU/WH)
Is the resistance less than 5 ohms?
- Yes:
- INSTALL a new DC / AC inverter. REFER to Direct Current-Alternating Current (DC-AC) Inverter . TEST the system for normal operation. If the AC outlet still turns off after 13 minutes when the engine is running, INSTALL a new BCM. REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) Or BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
- No:
- REPAIR the circuit.
- Measure:
