MONITOR DESCRIPTION The ECM monitors the input signals of the No. 1 accelerator pedal position sensor. If the input signals and control signals deviate, this DTC is stored. DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note P060D49 Internal Control Modul
Automatic High Beam System does not Operate or Operation Indicator does not Illuminate
DESCRIPTION The main body ECU (multiplex network body ECU) controls the automatic high beam system based on signals received from the forward recognition camera. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE:
Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
