PINPOINT TEST 1: THE HORN DOES NOT SOUND

Step 1 - 3:

Step 4 - 9:

Normal Operation
The horn relay B+ power is supplied through circuit (B/LG). The horn relay is controlled by the horn switch. The horn relay is grounded through the horn switches by circuit (Y/LG). When the horn switch is pressed, the horn relay control circuit (Y/LG) is grounded through circuit (B). The relay is then closed causing B+ voltage to be applied to circuit (DL), sounding the horns.

Possible Causes
- circuit (Y/LG) open
- circuit (B) open
- circuit (B/LG) open
- air bag sliding contact
- horn relay
- horn
- horn switch
- SJB
