- O1 CHECK CIRCUIT GD116 (BK/VT) FOR AN OPEN
- Key in OFF position.
- Disconnect: Hazard Lamp Switch
- Measure the resistance between the hazard lamp switch C2355-1, circuit GD116 (BK/VT), harness side and ground.
- Is the resistance less than 5 ohms?
Yes : GO to O2.
No : REPAIR the circuit. TEST the system for normal operation.
- O2 CHECK CIRCUIT CLS32 (BN/YE) FOR AN OPEN
- Disconnect: SJB C2280d.
- Measure the resistance between the hazard lamp switch C2355-5, circuit CLS32 (BN/YE), harness side and the SJB C2280d-20, circuit CLS32 (BN/YE), harness side.
- Is the resistance less than 5 ohms?
Yes : GO to O3.
No : REPAIR the circuit. TEST the system for normal operation.
- O3 CHECK THE HAZARD LAMP SWITCH
- Connect: Hazard Lamp Switch
- While holding the hazard lamp switch pressed, measure the resistance between the SJB C2280d-20, circuit CLS32 (BN/YE), harness side and ground.
- Is the resistance less than 5 ohms?
Yes : GO to O4.
No : INSTALL a new hazard lamp switch. REFER to HAZARD FLASHER LAMP SWITCH . TEST the system for normal operation.
- O4 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 CONTROL 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.
