ABS - 4WD - VDC WARNING LIGHTS

[hummer3t]

2013 QX56 153,000 miles. Driving to work these three warning indicator lights came on and remained on for the 20-minute drive. When I left work the lights remained on and during the 20-minute ride home they "all" turned off. Been over a week without a reoccurrence, until today. Today, all three warning lights came back on for the drive to and from work. Any ideas?

Here's the latest: the ABS & VDC Warning Lights seem to be permanently on, but the 4WD warning light is intermittent. Haven't found a solution, obviously it's an electrical issue, and fortunately I don't notice any change in the vehicle performance.

You won't get anywhere without a scan. There are only about a million things that can cause an ABS Christmas tree. If your scanner won't do ABS and transmission, most free scanners at the parts store will.

I didn't get any fault codes on my scanner, can't recall if it scans ABS or transmission. Will get back on this.

Had a scan completed today and got the following codes;
POWER TRAIN SYSTEM: P1557 Battery Temperature Sensor, Secondary DTC's P0725 Engine Speed Signal
ANTI-LOCK BRAKE SYSTEM: C1118 4WD Error, C1105 Rear Right Sensor 2

I thought it might be one thing easy to interpret.
but looks like we have to wait for VStar to chime in.

The C1105 is probably causing all of that except the P1557, which you can pretty much ignore. There's a problem with your righthand rear ABS wheel sensor.

Working on the ABS problem.
