Pinpoint Test B : B1305:01
- B1 CHECK THE HOOD SWITCH
- Disconnect: Hood Switch.
- Using a scan tool, clear the BCM DTCs.
- Using a scan tool, perform the BCM self-test.
Is the BCM DTC B1305:01 retrieved?
Yes REMOVE the jumper wire. GO to B2. No REMOVE the jumper wire. INSTALL a new hood switch. - B2 CHECK THE HOOD SWITCH GROUND CIRCUIT
- Connect:
Positive Lead Measurement / Action Negative Lead C127-1 Ground
- Using a scan tool, clear the BCM DTCs.
- Using a scan tool, perform the BCM self-test.
Is the BCM DTC B1305:01 retrieved?
Yes GO to B3. No REPAIR the ground circuit for an open. - Connect:
- B3 CHECK THE HOOD SWITCH SIGNAL CIRCUIT TO THE BCM FOR AN OPEN
- Ignition OFF.
- Disconnect: BCM C2280F.
Is the resistance less than 3 ohms?
Yes GO to B4. No REPAIR the circuit. - B4 CHECK FOR CORRECT BCM OPERATION
- Ignition OFF.
- 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 all 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 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 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.
