I need the ABS wiring diagram and plug pinout for a 99 chev venture van 3.4 250000 km I am now tracking a ABS light what are the voltages when you check wheel sensors and any other checks
Hammertime if you read this thank you for the help with the air bag problem. checked all the wires (after disconnecting all air bags) and found them good. the problem was under drivers seat the connections were loose someone before had taken seats out and NOT put the locks back in the connectors

To help you with what diagrams you need, what is the trouble code(s) that you are getting for the ABS system?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

All those codes are pointing to the LR speed sensor.
Did you inspect the harness and connector for damage or water intrusion?
The wheel speed sensor resistance is 1,030-1,180 ohms at 68 degrees F.
The wheel speed output signal is an AC voltage signal. If you connect your meter to the wheel speed sensor and rotate the wheel with it off the ground, you should see a voltage greater than 100 mV AC. The faster you spin the wheel the higher the voltage amplitude and the shorter the frequency.
The wheel speed sensor uses a twisted pair of wires. The LR speed sensor wiring uses one red and one black wire. They both go to the Electronic Brake and Traction Control Module (EBTCM) to connector C1 pin B2 and A3. They will be easy to find at the EBTCM connector because they are twisted.
I would post a diagram of the circuit, but I am getting leery of using the diagrams from the information source that I use. They are copyright protected and I don't want them knocking on my door.

The connector for the wheel speed sensor is on the hub bearing assembly. You can't miss it.
The EBTCM is located on the left side of the instrument panel above the parking cable bracket.
