New ABS sensor - still getting fault
#1
#4
I cleared the codes (have the Delphi DS150 scanner). Went out and did a drive will scanning. Would't you know, the brand new out of the box ABS sensor is bad. In fact, the original scanner looked good when watching the data (nice smooth speed curve) but was giving the code. Today I am going to swap in the old sensor and swap sides, see if it follows the sensor to rule out wiring or bearing issues.
I don't think it is a bearing issue though, the truck only has 130k on it and it is rear wheel issue, which usually don't give bearing wobble issues. And there is the fact that the data is smooth.

Update.
Swapped left and right, fault code came back - still on the left.
Swapped the slabs ecu with my other 03 - no fault for the left rear but there are three unknown faults - 135, 137, 138
Wireing from the plug near the fuse box to the frame rail is does not have the wire loom intact, thinking maybe there is some noise in the signal (although the data does not show it). Going to try the SRD500070 pn ECU, see if the higher level fault tolerance solves the problem, otherwise I am going to have to replace the wire harness.
BTW, faulty ecu works fine in the donor rover.

You may be sadly disappointed to find that a donor harness may have the same problem. Just run a pair of wires from each sensor to the control unit. Takes about 20 minutes to do.

Sounds like you have done this, where did you route the new wires to, through the firewall and directly to the ECM?

These cars are notorious for connector issues. There are two big connectors that are orange and grey near the expansion tank that are very problematic.
