PINPOINT TEST R: ONE TURN SIGNAL LAMP IS ALWAYS ON

Test R1-R3:

Normal Operation
Power is supplied from the central junction box (CJB) to the LH front turn signal lamp through circuits 29S-LF3 (OG/YE) and 29S-LF7 (OG/BU). The ground for the LH front turn signal lamp is passed through circuit 31S-LG11 (BK/WH) to the front electronic module (FEM). Power is supplied from the CJB to the RH front turn signal lamp through circuits 29S-LF4 (OG/BU) and 29S-LF16 (OG/GN). The ground for the RH front turn signal lamp is passed through circuit 31S-LG18 (BK/YE) to the FEM. The FEM individually controls the ground circuits for the front turn signal lamps. The timed on/off cycle is determined in the instrument cluster programming and is set to flash approximately 80 times per minute if both the front and rear turn signal lamps are good. If any turn signal lamp is not good, the instrument cluster will flash the remaining working turn signal lamp(s) approximately 160 times per minute.

Possible Causes
- circuit 31S-LG11 (BK/WH) short to ground
- circuit 31S-LG18 (BK/YE) short to ground
- FEM
