Both abs and traction control light stays on also spedo not working have checked all related fuses all ok have tried to scan with both snapon solus and launch x431 niether will communicate with abs ecu but will go into eng managment have you any ideas.The car is a 2000 vectra 2.2 petrol with abs/tc system thanks sash

have scanned for trouble code --check and test brakes--abs sensors--connectors --wiring and hubs

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

Probably not, but they are related to each other. Each system uses components of the other systems to function. So if one system fails the others can not work right.
Have the body computer scanned for trouble codes to proceed with testing.

this dealer is a joke abs maybe faulty sensor traction control try check the fuse on the fuse box if is blow replace if nothing happens needs a computer diagnostic

It is safe to drive. You need a scan tool to get a code out of it. Could be as simple as a wheel speed sensor going bad. All of these lights will work together normally. The traction control uses the ABS to gain traction, and the Brake Assist System is part of the stability control. Also uses the ABS.

Assuming you have right hand drive cougar, you can access the fuse box right under the glove box under dash. Use a torch and you will find a small pull down clip and when you pul it down it drops the whole fuse box. This is a common problem with Cougars. To my knowledge fuse is not the culprit, however its good to check. Most of the issues are related to ABS module. It is placed in the engine bay where it exposed to heavy vibrations (poor design) and some times the module will crack and sometimes it just electronic issue. Get the car scanned for fault codes and that will tell you what is the exact issue. If it turns out to be the ABS module you can get the module repaired if its not cracked or broken or buy a second hand one from wreckers if you can find one under $100 or $150. New one will cost a fortune. Let me know how you go, I can further assist in getting the module repaired, etc. FYI there is no need to remove or replace ABS unit if the ABS module is faulty. You dont need to touch it at all, just take out the ABS module (ECU).

The abs light , when on turns off the traction control thats why that light is on,once the abs is repaired the traction light will go out, you need to first have the computer scanned for codes, the codes for the abs are stored in the abs computer, these codes will tell you what part of the system is not working. most of the time its a wheel speed sensor but scanning the codes is needed to find out,

Chances are it is a bad ABS sensor. Need to get scanned to know for sure and which one.
Not much i know but I hope that helps.

Repair your vehicle right away. Just click on the link I attached 1997 Acura Cl Workshop Service Repair Manual

I assume tht is traction control. Check fuses ,eeven abs fuses ,traction control is part of abs. If fuses ok will need scan tool to find cause of lite going on. Most common are abs sensors and broken abs wires. And if abs tone ring is part of axle shaft some rock may have damaged teeth of ring .
