anyone ever pulled codes from thier ride control system from the trunk? Self test connectors on one of the flip down panels?
they are identical to the eec self test connectors.

ran across this in the shop manual a little bit ago and though i would ask.

Things i learned

no two codes starting with the same 10's digit can be stored at the same time,, ie 21 or 27 can not occupy memory at the same time. 21 and 37 can

code 27 can only show up only after the fault for 21 is found.

Codes that were not allowed to completly be displayed can not be erased.

clearing a code requires a brief jont down the road over 40mph to re-register codes that were cleared.

I also studied up on the TC's integrated relay contol box or whatever its called. Manual had pin outs for every wire/ its function ect. makes it easy to continuity check things out. there are two voltage regulators in there at the coil side of the fan relays iirc. above that , its really not all that complicated in there.

anyone?
if there is a need, Ill post up some shop manual info / pics.

I think the test connectors are on the pass flip down lid in the trunk.

I was wondering if anyone had pulled codes or not with the same process as we do with the eec.
