9000 - 9999: 9076

9076-HORN CONTROL CIRCUIT LOW





For a complete wiring diagram, Refer to the Wiring Information Electrical Diagrams.

- When Monitored:
Continuously.

- Set Condition:
When the Body Control Module (BCM) does not detect Voltage on the Horn Relay Control circuit.





1. TEST FOR INTERMITTENT CONDITION

NOTE: If any other DTCs are present correct those before proceeding with this test.

1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Operate the Horn Switch several times.
4. Cycle the ignition from on to off three times and leave on.
5. With the scan tool, read DTCs.

Does the scan tool display 9076-HORN CONTROL CIRCUIT LOW?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST. Verification Tests.

2. OPEN FUSED B(+) TO RELAY
1. Turn the ignition off.
2. Remove the Horn Relay from the Fuse and Relay Block.
3. Turn the ignition on.
4. Using a 12-Volt test light connected to ground, check the Fused B(+) circuit at the relay connector.

Does the test light illuminate?

No

- Repair the open Fused B(+) circuit.
- Perform BODY VERIFICATION TEST. Verification Tests.

Yes

- Go To 3

3. HORN RELAY
1. Turn the ignition off.
2. Install a known good relay in place of the Horn Relay.
3. Turn the ignition on.
4. With the scan tool, erase DTCs.
5. Operate the Horn Switch several times.
6. Cycle the ignition from on to off three times and leave on.
7. With the scan tool, read DTCs.

Does the scan tool display 9076-HORN CONTROL CIRCUIT LOW?

No

- Replace the original Horn Relay.
- Perform BODY VERIFICATION TEST. Verification Tests.

Yes

- Go To 4

4. HORN RELAY CONTROL OPEN
1. Turn the ignition off.
2. Measure the resistance of the Horn Relay Control circuit from the relay connector to BCM internal connector.

Is the resistance below 3.0 ohms?

Yes

- Replace the Body Control Module (BCM).
- Perform BODY VERIFICATION TEST. Verification Tests.

No

- Replace the Fuse and Relay Block.
- Perform BODY VERIFICATION TEST. Verification Tests.
