P1630

Communication Error from Skid Control ECU to HV ECU

While the vehicle speed is 40 km/h (25 mph) or more and the dynamic radar cruise control system is operating, communication data from the skid control ECU (brake booster with master cylinder assembly) is logically inconsistent for approximately 0.5 seconds or more.

  • CAN communication system

  • skid control ECU (brake booster with master cylinder assembly)

  • Hybrid vehicle control ECU

PROCEDURE

  1. CHECK CAN COMMUNICATION SYSTEM

    1. Using the GTS, check that the CAN communication system is functioning normally.

      OK

      CAN communication system is functioning normally.

      Tip:

      Refer to CAN Bus Check for the CAN communication system.
