suspension fault and only 30 mph
hi everyione and sorry for another post on suspension fault.
I've searchedthe forum, read all the trails i could find, done some activites already but I'm stuck.
so the car, has undertaken an engine swap after the crankshaft failing on me.\
during the rebuild, the frame has been roughly sanded and coverd with liquid sound proofing.
new compressor fitted (unfortunately after market and not an AMK)
new NSF or front left height sensor changed.
C1A08-1C PRESSURE SENSOR SUPPLY, GENERAL ELECTRIV FAILUARE, VOLTAGE OUT OF RANGE
C1A36-01 EXHAUST VALVE, GENERAL FAILURE INFORMATION, GENERAL ELECTRIC FAILUR
C1A03-1C FRONT LEFT HEIGHT SENSOR, GENERAL ELECTRIC FAILURE, CIRCUIT VOLTAGE
C1A00-53 CONTROL MODULE, SYSTEM PROGRAMMING FAILURE, DEACTIVATED
C1A00-54 CONTROL MODULE SYSTEM PROGRAMMING FAILURE MISSING CALIBRATION
after reading all the possible fixes in the forum i've done the following:
1. checked the front left sensor for signal on another corner, sensor working, although i bought a new one.
2. serviced and reinstalled my old compressor (AMK) and flashed the ECU with the correct firmware
3. test compressor and works
4. disassembled and serviced the central and the rear valve block
5. tested the valves from iidtool and they move
6. checked the front connector and loom, no visual damages or visible broken connectors or wires
7. checkd the nsr connectors and no visula damages or visible broken wires
8. reset the vehicle andattempted to do the calibration with no luck, as the FL height sensor is not giving the right reading
9. calibrated the steering
10. checked all fuse and relay
11. comperssor relay works
after swapping the compressor the faults c1a0053 and c1a0054 are gone.
i have also tried from the iidtool to deflate the corners and the tank, but becasue there is no signal to the exhaust valve none of the airbags actualy deflate.
the car is up to the max height and no leakage whatsoever.
i also have the follwoing faults, but i believe to be related and cosenquence of the suspension faults:
Headlight
U0400-68 INVALID DATA RECEIVED (EVENT DIAGNOSTIC TROUBLE CODE), ALGORITHM BASED FAILURE
VEHICLE CYNAMIC
U0421-68 INVALID DATA RECEIVED FROM RIDE LEVEL CONTROL MODULE, ALGORITHM BASED FAILURE
any further help or suggestion is more than welcome, as i believe the issue is in the loom as seems that all faults are related to missing signal going to the compressor, central valve block and LH height sensor
thank you
