I just got my IS back from the body shop this week, with it i got a whole new set of triggered CEL codes,

C0278

C1225

C0200
C0205
C0210
C0215

C1246

C1201


All these codes are ABS related so i think it can be narrowed down to 1 simple fix, if anyone can help me get these dash lights to turn off, My Emergency Brake light is always on, my trac off light is constantly blinking, and my check engine light is on

215 is a bad thermostat.
200 -210 is injector issue. check connections. otherwise it may be bad injectors.
1225 check connections at the throttle body.
1246 maybe a lose timing belt.
1201 is fuel pressure issue.

I'm not sure why you're not taking it back. If it didn't do this before you sent it to them, they fucked something up.

Usually when I see a bunch of unrelated CEL's I think there's a bad ground somewhere.

those codes don't match up to the ones I'm pulling, this is for a 2003 is300

Dooh well that's probably different.

Where was the repair? Was the car welded on? The ABS block under the hood is pretty much just as bunch of solenoids and valves. The actual electronics are under the dash. You could probably get those codes if you forgot to plug in some of the connectors under the dash.,

yes the car was welded on, it ran a high sidewalk curb, damaged the lower rad support on the passenger side so some cutting and welding was done, also the interior was completely redone,

what exactly under the dash would cause some of these issues?

The ABS block is near the impact area, it could be the issue but I highly doubt it was damaged, all the ABS and Skid Control electronics are inside...

Im getting a code for the master cylinder pressure sensor.

The way i see it it has to be something really simply...


c1201 is for malfunction in engine control system / ABS & TRAC ACTUATOR ,

then the 4 ABS wheel speed sensor codes,

the code for the brake actuator,

And the code for the ABS Solenoid...


can anyone put the dots together? im gonna try replacing all 4 wheel speed sensors maybe??? just replace everything until it works lol? i think i can find a parts car

Did you pull the ground before welding?

The connectors and ABS controller are right about where the clutch pedal would be under the dash. If you pull the lower dash cover and look up, you can see it. It's right about where the left knee is.

Sorry I forgot you had just C codes, not P...

Did you have these ABS codes when you dropped it off?

No, don't think it was throwing any ABS codes before it got dropped off, the car was in a small collision passenger side fender and lower rad support, then went straight to the body shop, never noticed until the car was fully finished.

yes the battery was pulled out during the welding, ill peek under my dash and check but I'm pretty sure none of those electronics were ever touched.

You're pretty much on your own here. Most people can't even read ABS codes much less fix them.

It sounds like something you did during the repair broke this so, I'd focus on that. Check the harnesses, check the grounds. I suspect you popped the ABS controller or cut/melted a harness.

Thanks for the insight, though i doubt something was damaged during the repair, most likely it was damaged during the little fender bender. I've checked the harnesses, Ill check the grounds again, I've reset the ECU and the codes come back, One thing that i find strange is that my E-shift still works, even with the speedometer not working,

Ill drive up to a parts car today and start replacing all ABS electronics one at a time then Ill report back later if any success.

These codes aren't coming from the ECU. They're coming from the ABS controller. Probably through the MX bus but that's just a guess.

In your shoes, I've get a volt meter and make sure all the power lines to the ABS controller and ABS unit under the hood are hot. I'd make sure the grounds are good too.

I had a subaru parts car that was in an accident, something pressed on the lid of the ABS unit under the hood 1/4". It was enough to ruin the ABS unit. Still that was an all in one unit. The electronics and plumbing was all in one box. On the IS the under-dash box is all the electronic for this I believe.
