2003 Chevrolet Suburban
5.3 V8
dash lights = yes after occurs the problem
codes = C0237
Transmission rebuilt
Done to repair = neutral safety switch speed sensor all
tech = jk
question = i have code C0237 this codes comes when i am driving around
30 mph and i go over i bump the brake light abs and rear speed
sensor this has speed sensor on the transfer case you can drive the truck
in the highway but as soon you go over i bump all this light comes
on any suggestion i disconnect all the speed sensor the abs module the
transmission module i move the pcm to a better place still the problem
there
JK:
There are 2 vehicle speed sensors (vss) on the transfer case. 1 on left, 1 on rt.,
furthest to the rear. Inspect those wires VERY carefully. Also inspect the wires all the
way back to the pcm under the hood. If all look ok, would suggest running new wires to
both sensors. Have had a couple trucks with similar concern, the wires test good,
pulling on wires does not should a broken wire, and had to run new wires to repair. Not
sure why, but that is what fixed them.

Chevrolet Suburban Tahoe ABS Codes
I have a 2003 Tahoe that the ABS will come on just as you near a complete stop. What should I look for?
2003 Chevrolet Tahoe 5.3
I did replace the left front wheel bearing approx 1 year ago. It did not fail, but did have a little movement. Problem
seemed to start about a month later.
This is a 4x4.

GM Tech JK:
The most common cause for this is a bad front wheel speed sensor, or the mounting surface of the sensor to the
hub has some corrosion on it, thus making the air gap between the sensor and reluctor wheel in the bearing too
great.
I asked about the turning because if that were the case, then i would suspect a faulty harness to one on of the
front sensors. The wires break inside the insulation and cause this problem when slowing as turning.
I would suspect that the problem is in the other side that has not been replaced. You can remove the speed
sensor, clean the mounting surfaces of any rust. Removing the sensor to do this would also indicate a bad
sensor if you remove the sensor and the outer sleeve of the sensor stays in the hub.
