B232A Description

 

Each optical track (received value) is monitored once a second while the rain sensor is active (WK Intermittent 1-5, LX intermittent 1-6) and compared to a small value. The optical track value must be below this value for 4 minutes (checked once per second) before this Diagnostic Trouble Code (DTC) will be set. Once the DTC is set, the optical track must be above the threshold for 4 minutes (checked once per second) before the DTC is cleared.
