Wiring diagram for TCS module

I'm looking for TCS/ABS module wiring diagram (Pontiac Trans Sport SE, Dec/1995, with Airbag). The Service Engine Soon light is off, but TCS lamp come on when I start driving.
Does anybody know how Traction Control System works? OBD2 scaner gives one error code- "torque out of range" only.
Does anybody know how to manualy disable TCS?

Sorry for poor my english.

You can manually disable the TCS with a switch. The switch is located near the rear fan control switch, in the middle, under the radio.

I will have a look in my service manual an see if I find something for you.

Thanks, Niklas,
I have service manual too, but I want to disable or repair this option. The switch near the rear fan control switch only switches system on another mode, but not disable it. Maybe dear LMP have a wiring diagram?

Well, I am refering to the GM Factory service manual, which contens all wiring diagrams as well as charts for DTCs.

I guess you have read DTC P1571 Traction control desired torque out of range? with a scanner, reading from the PCM (powertrain control module)? In that case DTC 124 should be stored in the EBTCM (electronic brake and traction control module). I guess you have not scanned the EBTCM.

DTC P1571 indicates a problem with the desired torque input to the PCM. The problem is either a wiring problem, or a bad PCM. I can email a copy of the DTC chart and related pages if you send me your email address.

Thank you very much, Niklas,

my e-mail adress- [email protected]. Any suggestions, information or links from you would be great.
Just as you say- I have read DTC P1571, but I don't have scaner (interface and software) for EBTCM. Have you got it or wiring for it? I have got OBD2 wiring and software from www.pontiac-interface.de.

See you, Arturas

I have sent you an email with the pages from the service manual that I think will help you. Yes, I do have software also for the EBTCM (ABS with TC control module) and I will email this to you as well. The EBTCM is hooked on the same wire (pin M) in the OBD connector, so your existing interface should work.

Thanks, Niklas, but I don't receive your e-mail for the meantime. Repeat please to another mailbox- [email protected]. I know that my PCM (16183247) hooked on EBTCM by OBD connector (M), but I have software for diagnostic ABS control module ('91-'94) only. I'm waiting... Thanks
