Thanks for your prompt reply - I feel helpless knowing this all comes down to an expensive loss... will urge her to report it and contact Isuzu - Yes, northern climate (PA - original owners), out of warranty by a year. Her insurance company won't even advocate for her, let alone consider financial remediation. Lord, you'd think we'd get what we paid for... |

I bought an Axiom for $7,000.00 within 3 weeks it started chugging, check engine light and reduced power light came on. I had to replace fuel pump, then carborator, then computer and a few other parts. Cost of $3500.00 thought that would be it. Ran for 3 good months, started stalling, check engine light and reduce power light on again. can't drive over 20mhp. now I'm told it is the wireing harness and might cost $1500-$4000 to fix. It is a piece of sssssshhhh.............tttttttt. I'm so mad. Cant afford to trade it in, cant afford to fix it anymore. Its just a driveway ornament. If I knew I would have bought something brand new.

Alex: Sorry to hear of the problems you have been having. I hope you did not buy a lemon vehicle. Still, I could use some more info on your situation, such as mileage and whether you took the car to an Isuzu dealer or a all-around mechanic, and any other pertinent info, such as why they think it is the wiring harness... I am doubtful about the diagnosis your mechanic gave you. When I experienced the symptoms you describe, it turned out to be a clogged EGR valve. This is a part you can remove with two bolts and clean with acetone and a wire brush. But the symptoms, CEL on, reduced power, sluggish performance, were essentially the same. But, there can be many causes. Luckily, I was able to drive my car to my local Autozone dealer and have them plug in their OBD SCAN Tool and tell me what the Check Engine Light code was. This is a free service at Autozone, and Advanced Auto Parts, too. Then I Googled the code and knew it was the EGR valve and then took it from there. So, before you torch your Axiom for the insurance money, why not get someone to check the CEL code for you and/or get a 2nd opinion from another mechanic? While it is possible that you could have a wiring harness problem, even the service manual I have does not suggest this as a possible cause, based on your symptoms. See if you can get the Check Engine Light code and post back here, so we can comment on that. But, I would not trust what you were told without some backup or a 2nd opinion By the way, the entire service manual is available online in PDF format for less than $20, and it details the troubleshooting procedures for this kind of problem in Chapter 6. Hope this helps... Bert, do you have any thoughts on this???. |

Some humble pie here: I poured over the Service Manual with your situation in mind, and it is very possible that there is a problem with the wiring harness that serves the PCM (Power Control Module), or the Multiplex Controller, which is why it would be important to know if there were any Diagnostic Test Codes set in your vehicle. Based on your description, it does sound like the Reduced Power Light is staying ON constantly after the vehicle is started, is that right? But, we do not know if there are any Diagnostic Test codes (DTCs) being set, without the SCAN TOOL scan I suggested earlier. Be aware that the Service manual says the following: "The RPL should not remain “ON” with the engine running and no DTC(s) set. A steady RPL with the engine running and no DTC(s) suggests a short to ground in the RPL driver circuit. An intermittent RPL may be caused by a poor connection, rubbed through wire insulation, or a wire broken inside the insulation." However, the problem can also be caused by a bad Multiplex Controller, or a bad PCM module, or in a best case scenario. a simple problem with one little wire leading from the Multiplex Controller to the RPL light in your dash's instrument cluster panel, or last but not least, a defective instrument cluster panel. (See diagram on page 1060 of the Service Manual below). Please look over the following three pages in PDF format. Download them and then post back here when you have them, so I can delete them, to keep my webmaster happy. I will leave them up for a few days for you: http://www.vivagen.net/Docs/2002_Isuzu_Axiom_US_Service_Manual_pg1060.pdf http://www.vivagen.net/Docs/2002_Isuzu_Axiom_US_Service_Manual_pg1061.pdf http://www.vivagen.net/Docs/2002_Isuzu_Axiom_US_Service_Manual_pg1062.pdf ********************* Bottom line, you should buy your own copy of the Service Manual online, then get a friend with a TECH 2 OBD SCANTOOL and lots of auto repair experience to check this out for you. You may be able to find and fix this problem yourself and save some $$$. Wouldn't that be great! I would hate to find out you have a loose wire that is easy to fix and the other guy missed it!!! Don't forget to post back here if you find a DTC code to share.

Replying to: bertbcfm (Jul 11, 2009 1:58 pm) I can't thank you enough - you're giving me the resources to help her. I didn't even know we had a State Insurance Commissioner... Funny, last Wednesday my husband paid a visit to the welding shop and apparently put this guy on notice, this morning he refused to touch the vehicle (finally got it up on a lift to look, with my girlfriend in attendance). Literally falling apart in rusty chunks - He said he wouldn't touch it if he couldn't guarantee her safety - (???). What I suspected all along, why did it take a visit from a man to 'compel' this guy's moral reasoning... I will let you know - thanks again. I'm so grateful I found this site.... Sherry
