Have replaced 2 bad rear wheel speed sensor. The OBDII codes are 600 and 720. and could not erase them using OBDII or battery disconnect. The service manual references using the DRBII for erasing DTC codes in OBDII and DRBII. THe DRBII scanner is dealer only and I am not ready for that exposure as yet.

The problem is that it is driving me to a CAB replacement that I need to confirm at $680. cost.
There are additional warning lights that confirm the CAB but want to make sure the Sensor did not correct the problem.

 

If it's a code you can't clear, then it's a continuously happening problem creating the code

 

Removed the brake, brake wear and engine lite dtr's with my OBDII scanner. Still had the ABS, BAS/ESP lite on. Read the manual about you can clear with DBRIII or disconnect the battery. In the small print it mentioned more than one trip might be needed.
So I disconnected/reconnect my battery and took it for a ride. at 25MPH the three went off and all have stayed off. One issue corrected with the codes in place the Shift into gear was heavy. With the 1st three codes eliminated the shift was normal.

The only thing left is the spoiler and it appears to be the panel switch that does not wring out. looks like a bear to get the radio out with out the right tool.

If your checking circuits in the system, the limits switch signal is a ground not an open that triggers the BCM to stop the spoiler both up and down.

I have externally run the motor both ways and checked it out both ways.
