WARNING:
Before beginning any service procedure, refer to Safety Warnings in General Information. Failure to follow this instruction may result in serious personal injury.
NOTE:
Do not set the ignition to OFF during the procedure. Setting the ignition to OFF causes the wiper motors to accept the current windshield wiper arms position as the initialized position.
NOTE:
Low battery voltage may prevent the BCM from entering Learn Mode.
NOTE:
If the FCDIM displays Low Battery Audio Off or the FDIM displays Battery Saver System Off, start the vehicle and set the ignition to OFF to reset the BCM.
NOTE:
Make sure the windshield is clean and dry before carrying out this procedure.
