PINPOINT TEST K: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Test K1-K3:

Test K4-K5:

Normal Operation
The electronic turn signal flasher receives its power in RUN/START through CJB fuse 21 (10A). The electronic flasher provides power to the multifunction switch through circuit 385 (WH/RD), 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 electronic turn signal flasher to the RF turn signal and right signal mirror bulb 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 electronic turn signal flasher to the LF turn signal and left signal mirror bulb through circuit 3 (LG/WH) and the LR turn signal bulbs through circuit 374 (DB/WH). Circuit grounds for the electronic flasher and each turn signal bulb are accomplished through grounding circuit 1205 (BK). The timed on/off cycle is determined in the electronic turn signal flasher 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 electronic turn signal flasher will flash approximately 160 times per minute.

Possible Causes
- Circuit 385 (WH/RD) open.
- Circuit 1205 (BK) open.
- Electronic flasher.
- Multifunction switch.
- CJB.
