DTC B1008:02 [FRONT BODY CONTROL MODULE (FBCM)]

System malfunction location	Windshield wiper control signal mismatch
Detection condition	• The front body control module (FBCM) receives 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

System malfunction location

Windshield wiper control signal mismatch

Detection condition

• The front body control module (FBCM) receives 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

Step	Inspection	Action
1	PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS START STOP UNIT • Clear DTC for the front body control module (FBCM) using the M-MDS. (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)].) • Switch the ignition ON (engine off or on). • Perform the DTC inspection for the front body control module (FBCM) using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) • Is DTC B1008:02 displayed?	Yes	Replace the start stop unit, then go to the next step. (See START STOP UNIT REMOVAL/INSTALLATION.)
No	Go to Step 3.
2	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the front body control module (FBCM) DTCs using the M-MDS. (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)].) • Switch the ignition ON (engine off or on). • Perform the front body control module (FBCM) DTC inspection using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) • Is DTC B1008:02 displayed?	Yes	replace the front body control module (FBCM), then go to the next step. (See FRONT BODY CONTROL MODULE (FBCM) REMOVAL/INSTALLATION.)
No	Go to the next step.
3	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].)
No	DTC troubleshooting completed.
