DTC B1008-02: Windshield Wiper Control Signal Mismatch [Front Body Control Module (FBCM)]: Notes

DTC B1008:02 [FRONT BODY CONTROL MODULE (FBCM)] DETECTION CONDITION AND POSSIBLE CAUSE

Description Windshield wiper control signal mismatch
Detection condition
  • Front body control module (FBCM) receives the error signals from the start stop unit with the ignition switched ON (engine off or on).
Fail-safe
  • If the front body control module (FBCM) cannot receive a windshield wiper switch position signal because of a malfunction in the start stop unit or a CAN communication error between the start stop unit, or if it detects an error in the windshield wiper switch position signal, it continues the control before detecting the malfunction. However, if the driver operates the wiper and washer switch, it controls as follows:
    • When the front body control module (FBCM) detects LO/HI ON using the LO/HI detection function: The windshield wipers are operated at low speed.
      • When the front body control module (FBCM) detects LO/HI OFF using the LO/HI detection function: The windshield wipers are stopped at the park position.
Possible cause
  • Start stop unit malfunction
  • Front body control module (FBCM) malfunction
