Test L: The Turn Signal Lamps Are Always On

PINPOINT TEST L: THE TURN SIGNAL LAMPS ARE ALWAYS ON

L1-L3:

Normal Operation
The smart junction box (SJB) sends reference signals to the multifunction switch through circuits CLS20 (BN/BU) (LH turn input) and CLS24 (BN/WH) (RH turn input). When the multifunction switch is placed in the LH or RH TURN positions, the voltage signal is routed to ground. When the SJB detects the multifunction switch in the LH or RH TURN position, the SJB provides voltage to the appropriate turn lamps.

DTC B2281 - is an on-demand DTC that sets when the SJB detects the RH turn signal switch input is short to ground.

DTC B2282 - is an on-demand DTC that sets when the SJB detects the LH turn signal switch input is short to ground.

Possible Causes
- Circuit CLS20 (BN/BU) short to ground
- Circuit CLS24 (BN/WH) short to ground
- Multifunction switch
- SJB
