Test M: The Turn Signal Lamps Are Always On

PINPOINT TEST M: THE TURN SIGNAL LAMPS ARE ALWAYS ON

M1-M3:

Normal Operation
The smart junction box (SJB) sends voltage reference signals to the multifunction switch through circuit 1393 (LB/RD) (LH turn signal) and circuit 1392 (LG/OG) (RH turn signal). When the multifunction switch is placed in the LH or RH TURN position, the signal is routed to ground.

Possible Causes
- Circuit 1392 (LG/OG) short to ground
- Circuit 1393 (LB/RD) short to ground
- Multifunction switch
- SJB
