B2298 – Rain Sensor Over Temperature

B2298 Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

B2298 Possible Causes

High ambient temperature,Faulty Light Rain Sensing Module (LRSM)

B2298 Description

The Body Control Module (BCM) is the Local Interconnect Network (LIN) master for the Light Rain Sensing Module (LRSM). The LRSM performs an internal self test and sends the information to the BCM. The repair of this fault condition does not involve any external circuitry and centers on verifying the integrity of the internal circuitry and software validity. The OBDII code sets when the Light Rain Sensing Module (LRSM) detects that the internal module temperature is higher than expected.
