Test M: The Turn Signal Lamps Are Always On

PINPOINT TEST M: THE TURN SIGNAL LAMPS ARE ALWAYS ON

M1-M3:

Normal Operation
Under normal operation, when RH or LH turn is selected, the multifunction switch sends a ground signal to the smart junction box (SJB) through (LH) circuit 1393 (LB/RD) and (RH) circuit 1392 (LG/OG). The multifunction switch is grounded through circuit 1205 (BK).

Possible Causes
- A short to ground in circuit 1393 (LB/RD) or 1392 (LG/OG)
- Multifunction switch
- Smart junction box (SJB)
