With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuit CBP20 (YE/VT). When the ignition switch is in the RUN or ACC position, voltage is received from the SJB through circuit CBP23 (BN/YE). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit SBP07 (WH/RD). The instrument cluster grounding is through circuit GD116 (BK/VT).
