Description
INFOID:0000000010430989
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 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 1 minute after the obstacles are removed with rear wiper OFF.
