4wd and asc off lights on after coilover install
 

Hey guys. Just installed my BC BR type coilovers today. Love em. Totally out of alignment now though. infact, my wheel is about 10 degrees right to go straight. I'm pretty sure this is what caused both my 4wd service light and ASC to go off at the same time. Especially as I literally just had my ACD pump replaced by mitsu yesterday.

Basically I just want to have some piece of mind that it's the alignment that's needed and nothing else. Everything else is hooked back up okay

Get it aligned and see what happens. Should get an alignment after any suspension work anyways. I think our cars are more affected because of the nature of the AWC system.

you sure u didn't break a sensor? my friend broke a wheel speed sensor on his rx8 when he installed his coilovers. ABS, Traction and Stability control lights came on when that happened. The sensor didn't look like it was broke until we pulled it out.

If it's only the AWC and ASC lights, then it's probably the alignment. When you break a wheel-speed sensor, you usually get all three lights; the above two, plus ABS. 99% likely that the alignment will solve the problem.

Why don't you think the codes are related tot he 'new' ACD pump? Good maintenance at the dealership would have been to clear codes (or find out why they are being generated now)...

I would first suspect the dealership work...

Two reasons. Let's do the embarrassing one first: because I didn't read the first post carefully enough to see no evidence that the pump replacement was done correctly. Now the better reason: because a bad pump will only trigger an AWC issue; it won't affect the ASC.

Ok just finished alignment. God I love these coilovers.....Anyway, the lights still pop up but I assume that's because they have to either be cleared or maybe the steering wheel sensor has to be recalibrated. Will try clearing while I'm re-flashing GST map today. If not I'll see if I can get it recalibrated.

And btw, given how far out of alignment I was, I'm pretty sure it was the issue. The dealer did clear the codes after the install. These lights came up the next day almost immediately following the coilover install. Btw the steering wheel was out almost 45 degrees, lol

Hey so update guys. All the lights turned off by themselves on the second drive since alignment

Oh, yeah. I can't really claim full marks for my prediction given that I failed to mention cycling the ECU a few times afterwards. Phui. But happy for you.
