Hello,

I Have GC 2012 limited v6.

A week back, all a sudden the battery dead and I have replaced it.
Three days back, it started to give me hard time to switch on. Either the car will switch on and off directly. or keep trying to switch on (Long crank) , after around 2-4 trial, it will work.

I think -but not 100% sure - no problem if the car is hot (e.g. switched off recently). only when I park for long time.


I have done some researches over the Internet and understood that the issue is in Fuel pump relay in the TIPM. Is that true ?

Please advise what is a reliable solution for the problem ?
I did not take it to the car dealer till now, it is weekend at this part of world.

 

Hello, After going through the post and some other over other forums, I concluded:
The TIPM has some faulty issues with relays. In my case, the fuel pump relay is faulty. To solve the problem, I have to follow one of these solutions:
1- Jumpering M25 with M7 (TIPM Bypass) e.g. http://store.verticalvisions.com/pro...her/TIPM1.html
Cost: 20 usd

2- Use an external relay e.g. http://www.verticalvisions.com/docum...1308000399.pdf
Cost 200-300 usd with car dealer

3- replace the whole TIPM with the new one 68244870AA
Cost 1000-1500 with car dealer

4- Fix the faulty relay with a new one. I think it is risky
Cost: 5usd for the relay + manpower fee

MY questions:
1- How can I be 100% sure it's fuel pump relay problem ?
2- Which one of the above option you recommend me ?
3- If I purchase the new TIPM (68244870AA) .. can I just replace it with my self (or with a help of a mechanic, not the car dealer) ?
or I have to go to the company for re-programming or something like that ?

Thanks ))

 

Research, research, research. Try google or bing. This TIPM problem has been discussed extensively on a lot of websites.

 

dave, did you see my reply ?!

 

Yes I did. Check out jkforum.com. They have a good thread about installing a new one without programing. It will do it itself if proper procedures are followed.

 

thank you. I will search there.

Anyway, the car is with the dealer now for checking, they will call me tomorrow for more information about the cost.

 

dealer fixed it by replacing it with an external relay for around 200 usd
