Description

FRONT WIPER MOTOR PROTECTION FUNCTION

• IPDM E/R may stop the front wiper to protect the front wiper motor if any obstruction (operation resistance)

such as a large amount of snow is detected during the front wiper operation.

• At that time turn OFF the front wiper and remove the foreign object. Then wait for approximately 20 seconds

or more and reactivate the front wiper. The wiper will operate normally.

REAR WIPER MOTOR PROTECTION FUNCTION

• BCM may stop rear wiper to protect the rear wiper motor when the rear wiper is stopped for 5 seconds or

more due to a snowfall.

• Rear wiper operates normally one minute after the obstacles are removed with rear wiper OFF.
