DTC B2967 or DTC indicator J and AUTO: An Open in the Humidity Sensor Circuit
- Clear the DTC with the HDS.
- Turn the ignition switch to LOCK (0), and then to ON (II).
- Do the Self-Diagnostic Function with the HDS (see HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITH THE HDS ) or the climate control unit (see HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITHOUT THE HDS ).
- Check for DTCs.
Is DTC B2967 or J and AUTO?
YES -Go to step 5.
NO -Intermittent failure, check for loose wires or poor connections on the humidity sensor circuit
- Turn the ignition switch to LOCK (0).
- Remove the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT
), and test it (see HUMIDITY/IN-CAR TEMPERATURE SENSOR TEST
).
Is the humidity sensor OK?
YES -Go to step 7.
NO -Replace the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT ).
- Disconnect the humidity/in-car temperature sensor 4P connector.
- Disconnect climate control unit connector B (12P).
- Check for continuity between the following terminals of climate control unit connector B (12P) and the humidity/in-car temperature sensor 4P connector.
12P 4P
No. 7 No. 1
No. 8 No. 2
No. 9 No. 3

Is there continuity?
YES -Check for loose wires or poor connections at climate control unit connector B (12P) 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; with navigation system (see WITH NAVIGATION SYSTEM ), without navigation system (see WITH NAVIGATION SYSTEM ).
NO -Repair open in the wire(s) between the climate control unit and the humidity sensor.
