Pinpoint Test C : B1305:01
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- C1 CHECK THE HOOD AJAR SWITCH
- Disconnect Hood Ajar Switch C127 .
- Ignition ON.
- Using a diagnostic scan tool, carry out the BCM self-test.
Is DTC B1305:01 still present?
Yes REMOVE the fused jumper wire. GO to C2 No REMOVE the fused jumper wire. INSTALL a new hood latch. REFER to: Hood Latch . - C2 CHECK THE HOOD AJAR SWITCH GROUND CIRCUIT FOR AN OPEN
- Connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead C127-2 Ground
- Using a diagnostic scan tool, carry out the BCM self-test.
Is DTC B1305:01 still present?
Yes REMOVE the fused jumper wire. GO to C3 No REMOVE the fused jumper wire. REPAIR the hood ajar switch ground circuit. - Connect a fused jumper wire:
- C3 CHECK THE HOOD AJAR SWITCH INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect BCM C2280C .
Is the resistance less than 3 ohms?
Yes GO to C4 No REPAIR the circuit. - C4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Disconnect and inspect all the 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. 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 TSB. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSB addresses this concern, Refer to BCM Hardware Testing . 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.
