DTC B1008-02; Windshield Wiper Control Signal Mis-Match: Notes

WARNING: This page is about a different car, the 2017 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & POSSIBLE CAUSE

Description Windshield wiper control signal mis-match
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
