Pinpoint Test
- CHECK THE SCCM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect: SCCM C2414A.
- Ignition ON.
- Measure:
SCCM Ground C2414A Ground Pin Circuit Measurement Pin Circuit 10 SBP23 (WH/RD) - -
Is the voltage greater than 11 volts?
- Yes: GO to 2 .
- No: VERIFY the BCM fuse 23 (15A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .
- CHECK THE SCCM GROUND CIRCUITS FOR AN OPEN
- Ignition OFF.
- Measure:
SCCM Ground C2414A Ground Pin Circuit Measurement Pin Circuit 13 GD214 (BK/BU) - -
Is the resistance less than 3 ohms?
- Yes: GO to 3 .
- No: REPAIR the circuit.
- CHECK THE HS-CAN
CIRCUITS BETWEEN THE SCCM AND THE DLC FOR AN OPEN
- Measure:
SCCM DLC C2414A C251 Pin Circuit Measurement Pin Circuit 14 VDB04 (WH/BU) 6 VDB04 (WH/BU) 15 VDB05 (WH) 14 VDB05 (WH)
Are the resistances less than 3 ohms?
- Yes: CONNECT the negative battery cable. GO to 4 .
- No: REPAIR the circuit in question.
- Measure:
- CHECK FOR CORRECT SCCM OPERATION
- Ignition OFF.
- Disconnect and inspect the SCCM connectors.
- Repair:
- corrosion (replace connector or terminals - clean module pins)
- damaged or bent pins - replace terminals/pins
- pushed-out pins - replace pins as necessary
- Reconnect the SCCM connectors. Make sure they seat and latch correctly.
- Operate the system and verify 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 SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) .
- No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
