'92 FX-3 Diagnostic codes

C4C5Specialist;
Can you briefly tell me the meaning of Ride Control codes 22-23-31-32 on a '92 LT1? Also, it would be great to know all the trouble codes for future reference. My manual gives only engine & emissions codes. Thank You!!! --- John A.

You need to get the elctrical book for the ABS, FX3, AC and other systems.

12 = Start of sequence
13 = Left rear time out
14 = Right Front time out
21 = Left Front time out
22 = Right Rear time out
31 = Left Front out of position
32 = Right Front out of position
33 = Left Rear out of position
34 = Right Rear out of position

Out of position codes are triggered if the computer senses that the actuator has not found the end stop position on the shock. Remove actuator at the indicated shock. Turn the valve gear on the shock stops after about 3 / 4 of turn, then you have a bad actuator. If it spins around continuously then it is a bad shock
41 = Selective ride control switch short to voltage
42 = Selective ride control switch open contacts
You can have a code 42 if you leave the switch in between indented positions

43 = selective ride control switch circuit open.

23 sets if you have keyed the system 3 times with out the car moving.
