Test L: One Turn Signal Lamp Is Inoperative/Always On
PINPOINT TEST L: ONE TURN SIGNAL LAMP IS INOPERATIVE/ALWAYS ONNormal Operation
When the smart junction box (SJB) detects a request for the LH or RH turn signal, the SJB provides voltage, through the bussed electrical center (BEC), to the front turn lamps through circuit 1342 (GY/BK) (LH front turn lamp) or circuit 1341 (DB/OG) (RH front turn lamp). The turn lamps are grounded through circuit 1205 (BK) through the BEC.
The rear lamps are combination stop/turn lamps. The function of the rear turn lamps uses the stoplamp circuitry.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Bulb holder
- BEC
- SJB
