Lost iACT/iQS

[MrSled]

Yes, tested with sled running. Nothing shows on the dash, nothing happens when I try and activate iQS with left hand control and no codes.

Sounds like its not loading when the key is on. I don't think its the switch. It takes about a min before you see the IQS screen load. If you have unplugged the box under the dash from the fuse box and it still don't see codes or anything try checking the fuse. My guess is the CDI is not seeing the IQS box.

When I unplug the module I get the no communication code. When I unplug any or all the shocks, no code. I get power to the module and the proper 60 ohms on the CAN lines and proper voltage. About 2.40 volts on low and about 2.54 on high CAN. That's back probing at the connector with it plugged into the module.

I am at a loss. Can you try someone else's IQ Box? Where are you located? I might still have my old box.

I'm in Ontario south of Barrie. I don't have access to another box. The dealer said they tried an new box but who know what they actually did.

See my post on page one when you first started this—- new dash is plug and play no programming needed—- that is what fixed my IQS issue—— I did switch hoods with my friends Tcat and Iact came up since it’s a cat hood …. Got a new dash and all good—-

Right!! They need to try a new box, then new gauge and then finally a CDI/ECU from an IQS. Not much left to try after that.

 

[j.e.1975]

The dealer claims they tried a used gsuge and a new gauge, new iQS module and a new handlebar control. The consensus after that is it has to be a wiring issue. I'm not finding any wiring issues. I'd like to swap the parts myself.

Did they swap the ECU/CDI? I had mine flashed for a tune and they removed part of my IQS. That tells me that's part of the system.

 

[j.e.1975]

They did not touch the ecu. I'm thinking it could be the ECU. I'm thinking about a PEFI stage 1 tune. I wonder if the tune would reflash my iQS back. Or can any dealer reflash the stock flash to correct the issue if it is the ecu.

 

[MrSled]

Mine was a Precision flash and when they updated it and reflashed I had it back. So maybe they could flash it back. Was it flashed before and maybe that’s why it’s gone?

 

[j.e.1975]

Stock tune as long as I've had it. Previous owner said it was stock from new.

I would give Precision a call.

 

[j.e.1975]

Yes. I'll update once I have more info.

I have another update. I unplugged the shocks to confirm if I get any codes from the shocks. No codes. jump ahead a couple days and a couple calls to dealers. The shocks won't give any codes unless the system tries to make an adjustment. So, tonight I fired up the sled and now I have some action. I get suspension DTC C1523, C1524, C1525, C1526, C1529 and C1530. These are stepper motor coil A and B faults for all 3 shocks. I don't think all 3 shocks are NG so I thinking it's the module.
Any suggestions or advice?

You are correct. The box is junk. I was telling you the sled has to be on to boot it into the gauge pod.
