DTC 2

DTC 2: A Short in the Air Mix Control Motor Circuit

1. Disconnect the air mix control motor 7P (4-door) or 5P (2-door) connector.
2. Disconnect audio-HVAC display panel 22P connector.




3. Check for continuity between body ground and audio-HVAC display panel 22P connector terminals No. 9, 13, 14, 17, and 18 individually.

Is there Continuity?

YES - Repair any short to body ground in the wire(s) between the audio-HVAC display panel and the air mix control motor.

NO - Go to step 4.




4. Turn the ignition switch ON (II), and check the same terminals for voltage.

Is there any voltage?

YES - Repair any short to power in the wire(s) between the audio-HVAC display panel and the air mix control motor. This short may also damage the audio-HVAC display panel. Repair the short to power before replacing the audio-HVAC display panel.

NO - Test the air mix control motor. If the air mix control motor is OK, substitute a known-good audio-HVAC display panel, and recheck. If the symptom/indication goes away, replace the original audio-HVAC display panel.
