DIAGNOSTIC PROCEDURE - HOOD AJAR CIRCUIT OPEN
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Open the Hood. With the DRBIII® in Inputs/Outputs, read the HOOD AJAR SW state. Does the DRBIII® display CLOSED? 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. No --> Go To 2 |

| 3 | Disconnect the Hood Ajar Switch connector. With the DRBIII® in Inputs/Outputs, read the HOOD AJAR SW state. Connect a jumper wire between Sense circuit and the Ground circuit. Does the DRBIII® display HOOD AJAR SW: CLOSED? Yes --> Replace the Hood Ajar Switch. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 4 |
