Pinpoint Test 2

PINPOINT TEST 2: THE HORN SOUNDS CONTINUOUSLY

Step 1 - 5:

Step 6:

Normal Operation
The horn relay is controlled by the horn switch, horn switch. The horn relay is grounded through the horn switch 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. The SJB can also supply a ground for the horn relay coil.

Possible Causes
- circuit (Y/LG) shorted to ground
- circuit (DL) shorted to power
- air bag sliding contact
- horn relay
- horn switch
- horn switch harness
- SJB
