Test Z: The Trailer Lamps Are Inoperative - Stop/Turn
PINPOINT TEST Z: THE TRAILER LAMPS ARE INOPERATIVE - STOP/TURN
Normal Operation
The trailer tow connector receives voltage for the stop/turn lamps through circuits 52 (YE) (LH stop/turn) and 64 (DG) (RH stop/turn), which are
fused protected by CJB fuses 42 (10A) and 36 (10A), respectively. Circuits 52 (YE) (LH stop/turn) and 64 (DG) (RH stop/turn) are spliced within the
CJB to circuits 9 (LG/OG) and 5 (OG/LB), respectively. When the vehicle stop/turn lamps are illuminated, voltage is also supplied to the trailer tow
connector.
This pinpoint test is intended to diagnose the following:
-
Fuse

Wiring, terminals or connectors
