Default 92 Bonneville SSEI ABS Pinout

Hey guys,

I am Working on the Teves Mark IV system on my car. Simple system yet very little detail over the internet regarding GM way to use it. (Wire colors, Pinouts, Schematics)

Lots and lots for BMW, Ford and so on.

Anyways, so my question is, can someone supply me a pinout of the Valve Module Connector and the Pump connector? ECBM connector to!

Thanks guys!

**Trying to Jumper bleed the damn thing!**

I moved your thread as this pertains specifically to your car!

You just made me cry...

Its pretty much any GM vehicle with a Teves Mark IV system.. Putting my thread in such an obscure location for such a specific and impossible to find (been browsing for 2+ hours with NOT 1 result linking to a GM vehicule!!) is made my real sad.

I really need the Pinout on the wire harness for the Valve Module and Pump.

I can find Ford and BMW pinout diagrams but they use a different shape/from connectors which make it useless. I really need a GM type!

Thanks!!

you must use a bi-directional scan tool to run the "auto-purge" process on the unit.

OTC and others make scan tools that can do this. The Teves Mark IV system that these cars have was very common and was in many GM vehicles
You should be able to find a shop that can do it.
My concern with just jumping things is a guess that the signaling isn't simply high and low. But maybe current driven rather than voltage. Thus jumpering pins wouldn't be sufficient.


And your right ill move it back sorry

Almost, but not true. There are workarounds. I just need the pinout. I am strapped for cash and have brought it to two garages already. I have new calipers, cylinders, all four flexes and master cylinder checks out OK. ABS never has worked when I bought the car so doing the redneck way of braking real hard in gravel multiples simply wont work.

I simple don't have the time for wait a round for a tech 1 unit or money to spend any where else.

To be more specific about my problem. Front Left and Rear Right do not bleed properly. They dribble. Sounds right since the brake lines are diagonally crossed. This means there is air before the calipers/cylinders.

Pedal goes to the floor but if I press hard enough, FR and RL wheels lock up. I simple have no braking power to the FR and RL.

Thanks!!

It'* all about grounding. The Valve Module is a constant +12VDC and has 2 valves per line/wheel; 1 inlet, 1outlet. Inlets valves are naturally open and fail safe open. Outlet valves are naturally closed and fail safe close. Grounding them either opens or closes the valves.

To manually jumper bleed the Module, you must jumper start the pump and let cycle for 20 seconds to build up pressure. Then purging is a simple process of grounding the required pins for the outlets valves (this will open them). Then to close again to let the pressure build for another 20 seconds. This is a 60 second process. Repeat if necessary.

I hope this shines some light on the subject.
