Pinpoint Test

CHECK THE HOOD SWITCH

Disconnect: Hood Switch.

Connect:

Hood Switch			Hood Switch

C127			C127
Pin	Circuit	Measurement	Pin	Circuit
1	CPL25 (BU/OG)		2	GD120 (BK/GN)

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 2 .
No: REMOVE the jumper wire. INSTALL a new hood switch.

CHECK THE HOOD SWITCH GROUND CIRCUIT

Connect:

Hood Switch			Ground

C127			Ground
Pin	Circuit	Measurement	Pin	Circuit
1	CPL25 (BU/OG)		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 3 .
No: REPAIR the ground circuit for an open.

CHECK THE HOOD SWITCH SIGNAL CIRCUIT TO THE BCM FOR AN OPEN

Ignition OFF.
Disconnect: BCM C2280F.

Measure:

Hood Switch			BCM

C127			C2280F
Pin	Circuit	Measurement	Pin	Circuit
1	CPL25 (BU/OG)		2	CPL25 (BU/OG)

Is the resistance less than 3 ohms?

Yes: GO to 4 .
No: REPAIR the circuit.

CHECK FOR CORRECT BCM OPERATION
1. Ignition OFF.
2. Disconnect and inspect all BCM connectors.
3. 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
4. Reconnect all BCM connectors. Make sure they seat and latch correctly.
5. 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.
