TEST DESCRIPTIONSteps 1-11:
The number below refers to the step number on the diagnostic table.
9. The horns need maximum current flow to operate properly. A high resistance - greater than 0.5 Ohms - 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.
