Haldex Infocentre ABS diagnostic connector

[engineer233]

My best idea was to move the battery switch so you don't grab it by mistake when in a hurry.

My best idea is to move the ABS on the circuit for the fuel solenoid.

Glad it worked for you. Good job !

Glad to hear you figured it out. I can find the 3 amp fuse on the right side of the steering column, good obvious since the light is on. Can't find the 15 amp on the left side or any side of the column. Have found several cut wires, haven't determined if they are for the radio.

It is there, near the steering column, but it is hard to find and get to, you need to shine a good light and get your body in there so that you can get your head all the way under.

Thank you. preparing to contort myself.

Found both fuses, both are good. ABS Still has light lit all the time, get no clicks when battery switch is on, and starter switch turned to run.. Having a hard time with the ABS troubleshooting TM. Wish it would show me a complete wiring diagram what wires go where, where the ecu is ect.. I have 4 wires coming from the abs light, 2 of them are cut off!

The wiring diagram is in the TMs. Are you using the -24 or the -23? The P2P also has a superb wiring diagram and pictures of each component. I would say a good start is to reconnect the two cut wires... That may be why your light is continuous and no-go on initialization.

-23, haven't installed the P2P yet but will next, I have it downloaded thanks. Problem is I can't find where the rest of the wire is that these cut off wires go to! Why the heck would they cut them off in the frist place? This was a radio truck, you'd think the wires going to the radio/s would be obvious.

 

[jonesal]

Here is the wiring diagram from P2P. Connect AND CHECK all the wires and then give it a try. I also suggest disconnecting and reconnecting all the ABS connectors, front to back, even at the EUC. Mine didn't work and it was just a corroded connection on one wire.



Good luck.

Thanks AL for all the help. It appears my yellow and purple wires are cut off from the light. Is the ECU the box mounted on the firewall in the engine compartment drivers side?

 

[jonesal]

No. It's on the frame above the middle axle.

Thanks Al. I followed the cable from the ECM/ECU. Apparently when they removed the radios from this truck they took the brutal approach cutting both thick cables coming through the firewall! Should be relatively easy to rectify. Of course when I went to print out the color schematic my computer that is locally hooked up to the color printer is DEAD. As in motherboard fried. It never ends does it?

 

[1 Patriot-of-many]

Luck wins out. Motherboard is fine, got out my Power supply tester, bad PS. swapped in a brand new PS and computer back up and running. Now to print off your suggestions and get to work.

Not to hijack the thread but I'm dancing on air! Identified which cable was the one(had five matching colored wires, other cable was for radio/s. Cut some of the sheathing back, stripped the wires, stripped the wires inside coming from the ABS light. One had a female plug on it had to crimp a male plug on one wire but unprofessionally used wire nuts and electrical tape for all the other connections. Got it done, hit the battery switch, then turned the starter switch to run. What did my ears hear? A front solenoid and a rear solenoid click then ABS light went out. YES! Fixed.

Sometimes it's just a simple fix that takes care of all our problems, but why is it they are always the hardest to find?

Hello, I went to check out my truck today. It does have a "Haldex" connector on the passenger side under the dash.

I bought a brand new Infocenter.

However, the connector on the truck is a four male pin connector. My Infocentre plug is two pin male and does not fit the connector. What is up with that?

In the package with the Infocentre that I bought, these is also an adaptor with two alligator clips, maybe I can hook them up to something?

Would love to get some pointers. Thanks

Did you ever get the "info centre" to work? I'd like to buy one as well, but being able to make it work is critical.

I did not get it to work, that it proved unnecessary in my specific case.
