Tests AF: DTC U2472 - Unexpected Ignition State

PINPOINT TEST AF: DTC U2472 - UNEXPECTED IGNITION STATE

Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster (IC) receives voltage from the SJB through circuits CBP10 (YE/OG), and CBP09 (VT/GY). With the ignition switch in the OFF position, the instrument cluster (IC) receives its keep-alive voltage from the SJB through circuit SCP33 (RD). The instrument cluster (IC) is grounded through circuits GD174 (BK/WH) and GD161 (BK/YE).

- DTC U2472 (Unexpected Ignition State) - is a continuous memory DTC that sets in the instrument cluster (IC) when the cluster detects a discrepancy between the hardwired voltage input and the messaged ignition state inputs from the SJB. The SJB messaged input indicates RUN while the hardwired input indicates RUN/START for more than 5 seconds.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- SJB
