TEST DESCRIPTION

Step 1 - Step 13:




Step 14 - Step 22:




The numbers below refer to the step numbers on the diagnostic table.
4. This step tests for voltage at the battery positive voltage terminal of the horn relay coil.
6. This step tests for voltage at the battery positive voltage terminal of the horn relay switch. The HORN fuse supplies power to the battery positive voltage terminal of the horn relay switch.
14. The horns need maximum current flow to operate properly. A high resistance, greater than 0.5 ohm, in the horn control circuit or the horn ground circuit could cause operating problems with the horns. Inspect the circuits for faults that would restrict current flow.
