I still have it with the wire I ran, should I hook back up the original wire before proceeding to check for the short to ground?

 

Yes, I would put it back to stock as a control so you can pinpoint the source of the fault.

Okay wiring is back to stock. When checking should I have the ignition on or off? I’m checking connectors infront of abs pump down to abs module correct?

 

When module is connected on stock wiring the fuse for the abs In the IPDM blows. When module is disconnected and new fuse is placed the fuse does not blow. Is this enough to condemn the module as faulty or could it be that the module is completing a circuit which is shorted to ground?

 

Two possibilities...

1) The module is internally damaged causing a short to ground.
2) The module is activating a relay and the load side of the relay has a short.

Which fuse exactly is popping in the IPDM? Can you give me the number and amp rating?

Also, when checking things like continuity and shorts to ground, it's best to have the ignition off. Ultimately it depends on what kind of trace is being done, sometimes it's best to have ignition power on when testing for voltage drop or current carry problems using a test light.

Thanks

The fuse popping is in the IPDM
it is fuse 83 a 15 amp

I began testing connector E118 with the ignition off doing a continuity test to ground. I started on pin 7 and got a reading of 23 m ohms this was with connector E 47 connected once I disconnected connector E 47 pin seven in connector E118 give me a reading of 0 ohms

 

That sounds right. Pin 7 on E118 is a relay control wire. The resistance value you saw was including the coil in the relay, which is why it disappeared when you pulled plug E47 from the VDC relay box. I don't know what the resistance spec is on the relay but 23mOhms is pretty big, no smoking gun yet.

Check pin 1 for short to ground. That is your ignition power (+12V) and runs to fuse #82 in the IPDM, which should be 10A. I don't see #83 mentioned in the circuit, but checking with my AI tool to confirm.

Seemed to fail to upload - regarding fuse

 

Is the fuse on 82 or 83 currently popped or removed?

Also, looking in my FSM copy (pg section), Fuse 83 is not used to power the ABS system, it's used to power the the TCM (transmission control module) & backup lamp relay. You problem may not be related to the ABS control module or Actuator/pump. It's probably your backup lamp relay or the TCM. That or there's a short at the IPDM.


Fuse #82 and #83 - both should be 10A

IPDM Type-1 layout

 

My mistake it’s fuse 82, second one down on top right section

Fuse was present and not blown when testing.

Fuse does not blow unless key is turned on, original wiring is connected and the abs module is hooked up. If the module is unhooked and I turn key it does not blow the fuse.

 

Ok, the power steering control unit is also on that fuse (#82). Need to look into that. So far it doesn't appear that you have a short in the wiring from the control side (ABS Control module). But there could be a short between the IPDM and ABS Actuator somewhere or something with the PS Control Unit, which I didn't even know these cars had. It could also be an internal short in the IPDM or internal short on the ABS control module. More testing needs to be done on the powers and grounds between these modules/actuators and the IPDM.

I will continue tomorrow. Was doing this on the side of my regular work. Clocked out for the night. I want to thank you again for your continued assistance, I wouldn’t be able to do it without your help.

Correct me if I’m wrong but what do you think about following the wire off the IPDM? The one that’s grounded and following that back to wherever it leads? Would you be able to provide that? I also attempted to scan the car and was unable to. This is new as I was able to scan it earlier this week when fixing a check engine light.

Even then I was unable to communicate with the abs module but was still able to communicate with pcm. Now I am unable to communicate with anything. I checked fuse for the data link and it was fine. I wanted to pull historical DTCs to see if I could get any info on the ABS or even the power steering but I was unable to even do that.
