ABS, HDC inactive, Air Susp Inactive faults - 2004 vogue

[nakedguy]

This week my dash has more lights than my xmas tree. The ABS light is on, the lcd is showing HDC inactive and Air Suspension inactive, also the traction control light is on to show that it is inactive.
This all comes after the track rod ends were done. I am wondering if it is all down to a failed ABS sensor as it is possible that one of those were damaged during the recent maintenance.
Can anyone shed any light?

Try turning your steering wheel from lock to lock. It can reset some of these faults. If that doesn't work, there's more to it.

Other thing to check is the condition of your battery. Alot of the electrics are sensitive to undervoltage, which is a sign that your battery is not keeping a full charge. Especially at this time of year when you have to have the heated seats, screens, steering wheel and lights etc on for just a short trip.

Highly recommend a battery check.
And or replace.

If this fault popped up immediately after the track rod end was changed it could be that the tracking is out causing the steering angle sensor to be picking up the wrong readings.
