Flip-Up Glass Ajar Circuit Open

Possible Causes:

• Flip-Up Glass Ajar Switch Ground Circuit Open
• Intermittent Condition
• Flip-Up Glass Ajar Switch
• Flip-Up Glass Ajar Switch Sense Circuit Open
• Body Control Module Internal Malfunction

Testing

1. Open the Flip-up Glass. With the DRBIII(R) in Inputs/Outputs, read the FLIP-UP AJAR SW state. Does the DRBIII(R) display CLOSED? If yes, the condition that caused this symptom is currently not present. Inspect the related wiring harness for a possible intermittent condition. Look for any chafed, pierced, pinched or partially broken wires. If no, go to next step.
2. Disconnect the Flip-up Glass Ajar switch connector. Using a 12-volt Test Light connected to 12-volts, test the Ground circuit for continuity. Does the light illuminate? If yes, go to next step. If no, repair the Ground circuit for an open. Perform BODY VERIFICATION TEST  .
3. Disconnect the Flip-up Glass Ajar Switch connector. With the DRBIII(R) in Inputs/Outputs, read the FLIP-UP AJAR SW state. Connect a jumper wire between Sense circuit and the Ground circuit. Does the DRBIII(R) display FLIP-UP AJAR SW: CLOSED? If yes, replace the Flip-up Glass Ajar Switch. Perform BODY VERIFICATION TEST  . If no, go to next step.
4. Disconnect the Body Control Module C1 harness connector. Disconnect the Flip-up Glass Ajar Switch harness connector. Measure the resistance of the Sense circuit. Is the resistance below 5.0 ohms? If yes, replace the Body Control Module. Perform BODY VERIFICATION TEST  . If no, repair the Flip-up Glass Ajar Switch Sense circuit for an open. Perform BODY VERIFICATION TEST  .
