- P1 CHECK CIRCUIT 1205 (BK) FOR AN OPEN
- Key in OFF position.
- Disconnect: Hazard Switch C2114.
- Measure the resistance between the hazard switch C2114-4, circuit 1205 (BK), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to P2.
- No : REPAIR the circuit. TEST the system for normal operation.
- P2 CHECK CIRCUIT 385 (WH/RD) FOR AN OPEN
- Disconnect: SJB C2280d.
- Measure the resistance between the hazard switch C2114-1, circuit 385 (WH/RD), harness side and the SJB C2280d-23, circuit 385 (WH/RD), harness side.
- Is resistance less than 5 ohms?
- Yes : GO to P3.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- P3 CHECK THE HAZARD SWITCH
- Connect: Hazard Switch C2114.
- While pressing and releasing the hazard switch, measure the resistance between the SJB C2280d-23, circuit 385 (WH/RD), harness side and ground.
- Is the resistance less than 5 ohms with the hazard switch pressed and greater than 10,000 ohms with the hazard switch released?
- Yes : GO to P4.
- No : INSTALL a new hazard switch. CLEAR the DTCs. REPEAT the self-test.
- P4 CHECK FOR CORRECT SJB OPERATION
- Disconnect all the SJB connectors.
- Check for:
- corrosion
- pushed-out pins
- Connect all the SJB connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
