Test M: The Turn Signal Lamps Are Always On

PINPOINT TEST M: THE TURN SIGNAL LAMPS ARE ALWAYS ON

M1:

M2-M3:

Normal Operation
The smart junction box (SJB) sends voltage reference signals to the multifunction switch through circuit CLS39 (VT/WH) (LH turn input) and circuit CLS41 (GY/YE) (RH turn input). When the multifunction switch is switched to 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 sends voltage to the appropriate turn lamps.

Possible Causes
- Circuit CLS39 (VT/WH) short to ground
- Circuit CLS41 (GY/YE) short to ground
- Multifunction switch
- SJB
