Pinpoint Test C: B1305:01: B1305:13

C1 CHECK THE HOOD AJAR SWITCH

Disconnect Hood Ajar Switch C127 .
Ignition ON.

Connect:

Positive Lead	Measurement/Action	Negative Lead
C127-1		C127-2

Using a diagnostic scan tool, perform 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.

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, perform 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.

C3 CHECK THE HOOD AJAR SWITCH INPUT CIRCUIT FOR AN OPEN

Ignition OFF.
Disconnect BCM C2280C .

Measure:

Positive Lead	Measurement/Action	Negative Lead
C127-2		C2280C-14

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, INSTALL a new BCM.
- 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.
