Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the central junction box (CJB) through circuits 640 (RD/YE) and 1003 (GY/YE). When the ignition switch is in the RUN or ACC position, voltage is received from the CJB through circuit 489 (PK/BK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the CJB through circuit 3049 (BK/LG). The instrument cluster grounding is accomplished through circuit 875 (BK/LB) and the bulb grounding is accomplished through circuit 57 (BK).
DTC B1360 - is set in continuous memory when the instrument cluster detects voltage on circuits 640 (RD/YE) or 1003 (GY/YE) with no voltage present on circuit 489 (PK/BK) for more than 15 seconds.
Possible Causes
- Circuit 489 (PK/BK) open
- Circuit 640 (RD/YE) short to voltage
- Circuit 1003 (GY/YE) short to voltage
- Instrument cluster
