HELP: 4wd and VSC/ABS codes

[slothy49]

Well, I’m lit up like a Christmas tree. It’s been well below freezing the last couple days and the cars been sitting outside through it. Went into town today using 4wd to help with icy roads, as I came to a stop my ABS, VSC, TC, and E Brake lights came on. I DID NOT engage the center diff lock. Scanned through, and I have all these codes coming up. Not sure if any have been there or if they’re all new. I know how to wrench but my diagnosis skills are near zero hahaha. 4wd still engages and disengages. Haven’t tried going into 4lo or locking the center diff. Any insight on this, or where should I start?

Codes:
C0210: Rear Speed Sensor RH Circuit
C1223: ABS Control System Malfunction
C1246: Master Cylinder Pressure Sensor
C1252: Hydro-Booster Pump Motor
C1340: Open Circuit in Center Differential Lock Signal (During Center Differential Lock
ON)

obviously a 2001 0r 2002.. Briefly had one with those lights on but not all those codes and it was an abs sensor. you show a rear sensor issue. The rear sensor is easy to check, its one bolt, I would pull it, and if its soaked in oil then you have an axle seal going out and the sensor might not be getting the right signal from the abs ring covered in oil. They built this rig to trigger multiple lights so you cant ignore them, but that does not mean you really have a problem with all of them. But why the other codes at the same time I dont know, I would clear codes and see if come back

Checking the fuses, also wires in the wire loom to the rear hatch wouldn't hurt. I saw a post a while back where, the ecu ig 10 amp fuse kept blowing due to short in the rear hatch wiring.
