If you search the topic here/google/whathaveyou you will find my posts... Since I bought my range it has done this.. 5 min into a drive I'll get all the lights and errors up.

Air suspension inactive/ HDC inactive/ DSC BRAKE ABS all illuminated.

Once you restart the car, codes reset and you're good to drive for another 5 minutes

I've had it at the dealer/indy shops, nobody can put their finger on the exact cause... Even after spending an hour on diagnostics...

After literally years of replacing bits here and there, researching how things communicate, I found MY fix...

No stored codes, but when the errors come up, test book throws codes for a wheel sensor, steering angle, yaw, few other things including ABS canbus

Everything functions fine for 5 minutes, but then the failure... After pulling sensors, cleaning them, shotgunning replacements I finally decided to pull my ABS module and take a look at the internals

Thank you for the tutorial, and accompany photos and explanation in detail.

I have had this combination of HDC, DSC, Trans Failsafe Prog and Air suspension inactive error, right after a short road trip of 2 hours & it was the end of trip car wash that painted my instrument panel an early Christmas lightshow 2023 (

How is your ABS module doing these days? Still running tip-top since your last modification?

very interesting
i have had that problem for a long time and got rid of it all to gether for quite a while but now its starting to come back again.
here is a post i posted three months ago, i live in australia so the weather is different.

OK you wont believe this
or am i the last one to know
The guy who lives across the road from me was over a few weeks ago. (he is a good mechanic)
He asked how the rover was going, I told him I was sick ok the three warning lights coming on. He said, have you cleaned the wheels lately
He said if he doesn’t clean the wheels on his holden he has all sorts of electrical faults, he has to clean them about every six month.
Come over he said
He got his pressure cleaner and squirted it through the wheels, cleaning the breaks etc.
A lot of dirt/dust washed out
The next three times I used the car, I had no warning lights, that never happened recently.
The lights still do come on, but after 40/50 km

Strange situation it seems but all these errors appearing seems to be linked to one single factor: Car Wash.

I can't help but link the ABS module malfunctioning due to moisture.

As my 2005 Rangie sat in the garage for the past 14 hours, and this morning when I started the engine, all errors have disappeared altogether.

I am contemplating on hunting down a used ABS module on eBay as a backup unit.

It could be the extreme daytime temperatures that I am currently facing at 40 degrees Celcius - ambient, and up to 65 degrees C internal cabin temp under the hot sun.

For now, it seems like this problem has gone away temporarily.
