Test R

PINPOINT TEST R: THE INDIVIDUAL FOG LAMP IS INOPERATIVE

Test R1-R2:

Normal Operation
When the SJB grounds circuit 1347 (DG/WH), the fog lamp relay switches voltage to circuits 1721 (LB/BK) and 1776 (TN/OG). Circuits 1721 (LB/BK) and 1776 (TN/OG) provide power to the LH and RH fog lamps respectively. Ground for fog lamps is supplied by the BEC through circuit 1205 (BK).

Possible Causes
- circuit 1721 (LB/BK) open
- circuit 1776 (TN/OG) open
- circuit 1205 (BK
- BEC
