DTC B10AD-87: Communication Error With Humidity Sensor/Solar Radiation Sensor/Auto Light Sensor/Rain Sensor
B10AD-87: (BCM) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Communication error with humidity sensor/solar radiation sensor/auto light sensor/rain sensor |
| Detection condition |
- The body control module (BCM) cannot receive the signals from the humidity sensor/solar radiation sensor/auto light sensor/rain sensor.
|
| Fail-safe |
|
| Possible cause |
- Malfunction in wiring harness (including connector/terminal) between humidity sensor/solar radiation sensor/auto light sensor/rain sensor and body control module (BCM) (See
CIRCUIT INSPECTION
.) (See
CONNECTOR INSPECTION
.)
- Humidity sensor/solar radiation sensor/auto light sensor/rain sensor malfunction (Refer to RAIN SENSOR INSPECTION
in service information.)
- Body control module (BCM) malfunction (Refer to BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION
in service information.)
|
| Repeatability verification procedure |
- Clear the DTC recorded in the memory. (See
CLEARING DTC
.)
