DTC B1008 62: Windshield Wiper Lo Switch Signal Mismatch: Notes

DTC B1008 62 DETECTION CONDITION AND POSSIBLE CAUSE

Description	Windshield wiper LO switch signal mismatch
Detection condition	The condition in which the CAN and module signals are compared and no match is detected between the signals for 5 s or more  with the ignition switched ON (engine off or on).
Fail-safe function	If the windshield wiper switch position which is monitored by the LO/HI detection function of the front body control module (FBCM) does not match the one which is sent from the start stop unit as a CAN signal, the windshield wipers are controlled according to the CAN signal for a certain period of time, After a certain period of time has elapsed, they are controlled 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 Windshield wiper switch malfunction Short to ground in wiring harness between start stop unit terminal 1V and front body control module (FBCM) terminal 2Y Short to power supply in wiring harness between start stop unit terminal 1V and front body control module (FBCM) terminal 2Y Open circuit in wiring harness between start stop unit terminal 1V and front body control module (FBCM) terminal 2Y Front body control module (FBCM) malfunction
