DIAGNOSTIC PROCEDURE - HORNS FAIL TO SOUND WITH ALARM TRIPPED
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the Low Beam Headlamps on. Do the Low Beam Headlamps operate properly? Yes --> Go To 2 No --> Refer to symptom LOW BEAM HEADLAMPS WILL NOT TURN ON . |
All |
| 2 | Turn the Headlamps off. With the DRBIII®, actuate the Headlamp Delay Relay. Do the Headlamps flash while actuating the Headlamp Delay Relay? Yes --> Replace the Body Control Module. No --> Go To 3 |
All |
| 3 | Remove the Headlamp Delay Relay from the Junction Block. Temporarily remove the Horn Relay from the Junction Block. Reinstall the Horn Relay in place of the Headlamp Delay Relay. With the DRBIII®, actuate the Headlamp Delay Relay. Do the Headlamps flash while actuating the Headlamp Delay Relay? Yes --> Replace the Headlamp Delay Relay. No --> Go To 4 |
All |
| 4 | Remove the Horn Relay from the Headlamp Delay Relay location in the Junction Block. Reinstall the Horn Relay to its original location. Measure the voltage of the Fused B(+) circuits at the Headlamp Delay Relay connector. Is the voltage above 10.0 volts at each cavity? Yes --> Go To 5 No --> Refer to symptom HEADLAMP TIME DELAY INOPERATIVE in EXTERIOR LIGHTING. |
All |
| 5 | Remove the Headlamp Delay Relay from the junction block. Remove the BCM from the junction block. Connect a jumper wire between the Fused B(+) circuit and the Headlamp Delay Relay Control circuit at the Headlamp Delay Relay connector. Measure the voltage of the Headlamp Delay Relay Control circuit (cavity 5) in the BCM internal connector. Is the voltage above 10.0 volts? Yes --> Go To 6 No --> Replace the Junction Block. Perform VTSS VERIFICATION TEST - 1A . |
All |
| 6 | Disconnect the jumper wire. Reinstall the Headlamp Delay Relay in the Junction Block. Remove the BCM from the junction block. Measure the voltage of the Headlamp Delay Relay Control circuit (cavity 5) in the BCM internal connector. Is the voltage above 10.0 volts? Yes --> Replace the Body Control Module. Perform VTSS VERIFICATION TEST - 1A . No --> Replace the Headlamp Delay Relay. Perform VTSS VERIFICATION TEST - 1A . |
