IG2 Signal Circuit Short to Auxiliary Battery (P253012)

DESCRIPTION The hybrid vehicle control ECU compares the IGP signal to the IG control status signal sent from the certification ECU (smart key ECU assembly) to detect a stuck on malfunction of the IGP signal. HINT: If DTC P253012 is stored, the ignition switch will turn off (READY off). DTC

Operating Light Control Rheostat does not Change Light Brightness

DESCRIPTION The combination meter assembly receives signals from this circuit to adjust the illumination of the combination meter assembly. The combination meter assembly sets the illumination level based on the user operation of the light control rheostat switch. WIRING DIAGRAM CAUTION / NOTICE
