Pinpoint Test
- CHECK THE RUN/START RELAY
- Ignition OFF.
- Disconnect: RUN/START Relay.
- Carry out the appropriate relay component test.
Refer to OEM Wiring Diagrams - COMPONENT TESTING for schematic and connector information.
Is the relay OK?
- Yes: GO to 2 .
- No : INSTALL a new RUN/START relay.
- CHECK THE RUN/START RELAY CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
- Measure:
BJB Ground RUN/START relay Ground Pin Circuit Measurement / Action Pin Circuit 1 CDC55 (BN/VT) - Ground
Is any voltage present?
- Yes: REPAIR the circuit.
- No : GO to 3 .
- Measure:
- CHECK FOR CORRECT BCM OPERATION
- Disconnect and inspect all BCM 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 BCM 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 BCM. REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) , or REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) .
- 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.
