Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuits (Y/O), and (V/GY). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit (R). The instrument cluster is grounded through circuits (B/W) and (B/Y).
Possible Causes
- Fuse(s)
- Circuit (V/GY) open
- Circuit (Y/O) open
- Circuit (B/Y) open
- Circuit (B/W) open
- Circuit (R) open
- Instrument cluster
CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
