PRE-CRASH SAFETY SYSTEM, Diagnostic DTC:C1A63

DTC Code DTC Name
C1A63 Accelerator Pedal Position Sensor Circuit

DESCRIPTION

The pre-crash safety city sensor receives accelerator pedal position sensor signals from the hybrid vehicle control ECU assembly and determines whether acceleration is requested by the driver. When the hybrid vehicle control ECU assembly detects a malfunction in the accelerator pedal position sensor, the pre-crash safety city sensor is notified via CAN communication and this DTC is output.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1A63 Accelerator Pedal Position Sensor Circuit Once 3 seconds or more have elapsed after the power switch is turned on (IG), an accelerator pedal position sensor malfunction signal is continuously received from the hybrid vehicle control ECU assembly for 5 second or more while the IG voltage is 10 V or more.

  • Hybrid control system

  • Hybrid vehicle control ECU assembly

  • Pre-crash safety city sensor

CAUTION / NOTICE / HINT

Note


  • When replacing the pre-crash safety city sensor, replace it with a new one and be sure to initialize the settings. If a pre-crash safety city sensor which was installed to another vehicle is used, the information stored in the pre-crash safety city sensor will not match the information from the vehicle and, as a result, a DTC may be stored.

  • If the pre-crash safety city sensor has been replaced, or the windshield glass has been replaced or removed/installed, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.
