Well, Jon,

In trying to respond I deleted your photo. I think that instead of clicking Quote, I clicked Edit, and proceeded to type assuming I was creating a new post that quoted yours. Instead, I was editing your post, and the first thing I did was to delete the photo so it wouldn't take up space in the quotation in my post! Obvioiusly, I'm dangerous with moderator tools at my disposal.

Your photo shows the safety strap for the hydraulic engine mount, which is not an electrical conductor. I believe it just prevents catstrophic separation of the mount.

Please post the photo again if you get a chance. I'm very sorry I messed up!

Cheers,

Don

 

 

Hmm, been doing some mental aerobics, trying to deduce what would happen if the engine’s ground cable was indeed missing.

I've seen this on other vehicles. The typical symptom is the starter cranking speed is slow. With the proper ground path interrupted, current will find some other route to ground, such as via the transmission and driveshaft, metal fuel lines, etc.

But Jon did say the starter cranked okay when the relay was jumpered. That suggests the ground path is adequate, even if not perfect.

For some quick troubleshooting, you could attach a temporary ground cable. One side of jumper cables would be perfect. No need to crawl underneath. Connect one clamp to a convenient bare spot on the engine. Connect the other end to a good ground on the chassis. See what happens.

 

Do you still have the 'Steering Column locked' message on the dash?
If so, I think this may be your problem. I have the same messsage and no start since the battery lost voltage after sitting without the car being used for a few weeks. I have read that the Steering Column lock needs to be calibrated using JDS in my case but maybe IDS in yours? I can't confirm this fix yet as I'm having difficulty installing the software onto a dedicated laptop even though it is running XP Pro, SP3 as required. You can install on a virtual machine though if you have a later laptop; I don't :-(.

 

hey mate. Yes still locked. I am running ids legacy in a virtual machine. Problem is once ive read codes all modules lose serial comms. So I camt reset anything.

 

@JonTheHorrible

Any updates? Wish I had something concrete to suggest but am drawing a blank.

Did you see this recent thread? Some of the symptoms were similar:

Got me wondering what would happen if you tried unplugging various modules one at a time. I was thinking the RECM, but the parking aid module is another candidate. Just thinking out loud. Maybe a module has failed in such a way it’s interfering with the data bus and causing the no comm. Unplugging the RECM won’t “fix” anything (and obviously the engine won’t start), but if the no comm clears up, you’d know where to investigate further.

 

Hey mate. No nothing to report. I have been unpligging modules. Tried the rear ecu and the ans so far. Will be trying the steering module this qeekend when I get a chance.

I have a feeling it might be that. But have had a lot of feelings it might be something only to find it wasnt so far.

 

When I bought the car, the passenger carpet was a little sticky. Turns out this could be a leak from my heater. Google suggests I lift the carpet and sill cover and check the connection there, esp to the SCP bus. This is pretty close to the starter. It is possible that when I plugged the batter in without the starter connected, to lock the doors to leave the car overnight, it may have been the path of less resistance to a spike. I am going to wait til it stops raining (has been raining for 4 days, welcome to Sydney) and clean and dry this area. Maybe that will clear up the possible "noise" on the network and let me clear codes etc.

A long shot, again makes sense, again something that seems like a smoking gun, but I've had a lot of smoking guns that proved not to be a problem. I miss my car, Uber is draining my bank!

 

Is the PCM (aka ECM) OK? On some/all of these cars it's roughly vertical above there, behind glove box / through firewall. They hate being wet!

 

Another thought, of unknown value:

When you were changing the starter, was it raining? If so, did you have the front end raised for access?

More thinking out loud, but if the front end was tipped up and the car sat like that for some time, rain may have run down a different path than normal. Perhaps water collected in a normally dry location? The PCM comes to mind, as suggested above.

 

Hey thanks guys. It had been raining amd rained lightly on and off during the 7 hours or so it was raised. Im going to pull up the carpet and look at that wiring and ecu today. I just got a decent obd for it that seems to have cleared some codes already. So my passenger window works now but nothing else noticeable. Although it has proved comms with a lot of modules. And I know now my cluster is ok too.

I have contact cleaner, bonding silicon tape and a heat gun at the ready for the junctuon box there. Let's hope I clean it all and repair any corrosion and it suddenly I start seeing some different results.

The IDS software is crazy. In case it happens to anyone else, don't ever enter your vin manually then click go. Always press enter after typing insteadi. Hours wasted waiting only for it to say I entered an incorrect vin of ?????????????????? Every time.

 

Do I understand correctly that the no-comm issue has been resolved (or at least improved significantly) by getting a different scanner? If so, that is great news. Here's hoping for more good news in the near future.

 

More narrowed down really. I cant see the steering lock modulator or the rear ecu on the network.

 

im missing the rear ecu and steering lock module from scans. But we had heavy rain and now im missing lots. Bit of water in the boot too.

Its sporadically showing a few modules then they vanish. Looks like its kaput 😞

Currently enquiring about a 2003 v6 online instead. Its 2700 dollars. Likely a lot cheaper than fixing mine

 

the column lock is a slave of the cluster. cluster has to be configured to ignore it at least on x202 and later.

 

Thanks mate. Mines an x200. But yes the cluster still has a final say in things. The cluster tests fine. Its something to do with front to rear wiring or possible a borked rear ecu I reckon. Im taking my time over it now as it's run out of registration. Just hoping for a weekend where I can either fix or definately identify the problem now.
