air suspension 143 Damping Adjustment Valve problem

[royxaxa]

Parked my 04CTT on a slope for the day. started the car in the hot afternoon and the following problem occurred:

air suspension work shop.

Durametric shows the following code:

143 Damping Adjustment Valve front right

Electrical fault

after deleting the code and drive it around, the same 143 code came back again and with another error:

1437 Control Position not learned

No/incorrect coding/calibration

I checked the actual value:

shock absorber valve current FR 0.000A while the other 3 are around 0.04A while car is parked

the level control seems okay and car drives normal.

does it mean that I have to replace the whole front right shock?

thanks guys

Anyone could post the 143 error code diagnostic procedure please

Thanks

Thanks Loren, but 143 and 147 are the same codes?

I am a little confused. :unsure:

Sorry, my typo... let's try this...

Fault code 0143 -- Damping adjustment valve, front right

Possible cause of fault

- Short circuit to ground or open circuit in the wiring of pin 116 of the level control module (electrical fault in electric circuit)

- Short circuit in pins 116 and 118 of the level control module wires with respect to each other (electrical fault in electric circuit)

- Short circuit to B+ in the wiring of pin 116 of the level control module (electrical fault in electric circuit)

- Short circuit to B+ or open circuit in the wiring of pin 118 of the level control module (electrical fault in electric circuit)

- Short circuit to ground in the wiring of pin 118 of the level control module (electrical fault in electric circuit)

- Damping adjustment valve faulty

- Level control module faulty

Loren thank you for your support.

I took apart the connectors near the lower end of the struct.(there are two connectors, one is acceleration sensor, the other is, I suppose, the struct absorber valve) and cleaned them up. the code was gone, at least for one night. I will see if it comes back, hopefully not, and let you guys know.
