Test J: The Turn Signal Lamps Are Always On

PINPOINT TEST J: THE TURN SIGNAL LAMPS ARE ALWAYS ON

J1-J3:

Normal Operation
The smart junction box (SJB) sends a voltage reference signal 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 through the SJB.

DTC B2281 - sets when the SJB detects a short to ground from the RH turn signal input circuit.

DTC B2282 - sets when the SJB detects a short to ground from the LH turn signal input circuit.

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