DTC B2967 or DTC indicator M and AUTO: An Open in the Humidity Sensor Circuit

1. Clear the DTC with the HDS.
2. Turn the ignition switch OFF, and then ON (II).
3. Do the self-diagnostic with the HDS or climate control unit.
4. Check for DTCs.

Is DTC B2967 or M and AUTO indicated?

YES - Go to step 5.

NO - Intermittent failure, check for loose wires or poor connections on the humidity sensor circuit.

5. Turn the ignition switch OFF.
6. Disconnect climate control unit connector A (32P) and B (16P).
7. Disconnect the humidity/in-car temperature sensor 4P connector.




8. Check for continuity between the given terminals of climate control unit connector A (32P) and B (16P) and humidity/in-car temperature sensor 4P connector.

Is there continuity?

YES - Go to step 9.

NO - Repair open in the wire(s) between the climate control unit and the humidity/in-car temperature sensor.

9. Reconnect the humidity/in-car temperature sensor 4P connector.
10. Reconnect climate control unit connector A (32P) and B (16P).
11. Test the humidity temperature sensor.

Is the humidity sensor OK?

YES - Check for loose wires or poor connections at climate control unit connector A (32P) and B (16P) and at the humidity/in-car temperature sensor 4P connector. If the connections are good, substitute a known-good climate control unit, and recheck. If the symptom/indication goes away, replace the original climate control unit.

NO - Replace the humidity/in-car temperature sensor.
