To run a self-diagnostic for the DCC:

Turn engine on, within 10 seconds of starting engine, press and hold ‘OFF’ button on the ACC for 5-10 seconds until all segments on the display light up.

 

Test 1- Display Test

Look for any missing segments or icons.

Press Up arrow to get to Test 2.

 

Test 2 – Input signals from each sensor

Wait a couple seconds and it’ll display error codes (20=all ok, 21=ambient, 22=in-vehicle, 24=intake, 25=sunload (test in sunlight to prevent this error), 26=PBR)

Press Up arrow to get to Test 3 or Down arrow to get to Test 1

 

Test 3 – Mode Door Motor

This test takes a little longer. 30=all modes ok, 31=vent, 32=B/L, 33=B/L, 34=Foot/Def 1, 35=Foot/Def 2, 36=Def

Press Up arrow to get to Test 4 or Down arrow to get to Test 3

 

Test 4 – Actuators Test Pattern

Toggle modes 41-46 by pressing defrost button on ACC.

 

Test 5 – Temperature Readings

Press defrost button to toggle through sensors (ambient, in-vehicle, intake in that order). If the temp is -22, then that sensor is not working. The temperature can also be adjusted to compensate for differences between temp setting and the temp felt by driver. It can be adjusted 6 degrees up or down. While in Test 5, press the fan switch and then the temp adjustment can be made using the Up/Down arrows.

 

Hit Auto button or turn car off to exit self-diag.

Nice one!, I did this to test my Actuators and when I toggled through test 4 it blew my ACC fuse in the cabin.

I'm thinking that its due to the fact that I need to r-gas my AC?

 

Anyone know?? :huh:
