PINPOINT TEST L: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Test L1-L2:

Test L2-L4:

Normal Operation
The indicator flasher relay receives its power in ON/START through CJB fuse 21 (5A). The indicator flasher relay provides power to the multifunction switch via CJB fuse 5 (15A), then through circuit 44 (LB), which provides power to the turn signal lamps depending on the position of the multifunction switch. When the multifunction switch is placed in the RH position, current flows from the multifunction switch to the RF turn signal through circuit 2 (WH/LB) and the RR turn signal bulbs through circuit 378 (BN/YE). When the multifunction switch is placed into the LH position, current flows from the multifunction switch to the LF turn signal through circuit 3 (LG/WH) and the LR turn signal bulbs through circuit 374 (DB/WH). Circuit grounds for the indicator flasher relay and each turn signal bulb are accomplished through grounding circuit 1205 (BK). The timed on/off cycle is determined in the indicator flasher relay and is set to flash approximately 80 times per minute if both the front and rear indicators operate. If only one turn signal lamp operates, the indicator flasher relay will flash approximately 160 times per minute.

Possible Causes
- circuit 44 (LB) open or short to ground
- circuit 1205 (BK) open
- indicator flasher relay
- multifunction switch
