If the rear wheel hub in the affected vehicles is submerged in salt water, salt water can enter the rear wheel speed sensor housing and may interrupt the rear wheel speed sensor signal and temporarily illuminate the ABS and/or ESC warning lights in the instrument cluster until the sensor dries. For these cases, replacement of the wheel speed sensor cap is required. If no ABS/ESC warning lamp is illuminated, applying a silicone spray to the sensor is required. This bulletin describes the service procedure for the rear wheel speed sensors.
