07 and 08 JK - Antitheft System - Engine No Crank/No Start Condition - July 08

Antitheft System - Engine No Crank/No Start Condition

NUMBER: 08-007-08 REV. A

GROUP: Electrical

DATE: July 04,2008

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 08-007-08, DATED MARCH 04, 2008. THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.

DO NOT ORDER PART NUMBER 05026070AP UNTIL JULY 21, 2008. ALL OTHER PART NUMBERS ARE AVAILABLE NOW.
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM

OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also referred to as the Sentry Key Remote Entry Module (SKREEM).

MODELS:
2007 - 2008 (JK) Wrangler

NOTE :This bulletin applies to vehicles built on or before May 05, 2008 (MDH 0505XX).

SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the remote keyless entry (RKE) system will not operate. This condition may be due to an electrostatic discharge (ESD) from the ignition key into the Wireless Control Module (WCM), causing the WCM to electronically lockup. This condition may occur more frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is more easily produced. This condition is corrected by the replacement of the WCM.

Lance,

Thanks for posting this. My 07 Rubi did this last week, I had no idea what was going on. I called the dealer, they did not mention anything about a TSB being issued, in fact they didn't even have a fix or a suggestion about a fix. They wanted me to have it towed to the dealer for diagnosis, which I could have. Before I did that, however, I tried the battery unhook just on a whim. That reset the module, I guess, 'cause everything works again. I wonder if it is going to happen again...if it does, I guess I'll have it towed in then so they can see what is happening. I don't know if they can tell if the module is bad unless nothing is working.

If it happens again you do want to take it in so they can replace the module. From what I understand the new module is not susceptible to electro static discharge like the original one.

In your opinion, would it be worth scheduling a service visit based on the fact that it happened once already, even though everything is working now?

If you have the lifetime warranty still it should be covered by that. If you are not under warranty (like me). Then just keep a fuse puller in your glovebox and pull M13 out of the fusebox for 30 seconds if it happens to you.

Mine has done it once in the three years I've bought it.

I just came across this post, and wish I would have found it sooner.
I had this happen to me a few Fridays ago after work. Had it towed.
The dealership said they fixed it, stating "it was an issue with the key losing programming" I picked up jeep Saturday, drove fine all day Sunday. Go to start car for work Monday and same issue. Made dealership tow it on thier dime. They took a day and a half to say it was the same/similar issue. Fix was no charge(niether was tow).
Last service invoice shows:
Job#1 68001702-AA Key Blank

So I called service and talked to the clown(service manager) who was handling my issue. He stated that he replaced the WCM the first time. The 2nd he had to replace the chip in main key that was used (I left both keys and told him to make sure they both work). So far its working without issue.

Is there another alternative to pulling the fuse, if it happens again?

Keep in mind that the " lifetime warranty " is on the power train only. Also I have been warned by the service manager at my stealership that Chrysler is checking records to insure you have preformed all of the "Required maintenance" and voiding the warranty if you have failed to do so.

FN POS

Happened to me today. Remote wouldn't work so I opened it with the key. Alarm went off and wouldn't stop so I disconnected the battery. Finally got it to start and went home for lunch with all the idiot lights on. After lunch, tried to start it and nothing. Disconnected and reconnected the battery, tried all the remote buttons on both keys, nothing. Called the tow truck and went off to the stealership. $100 to look at it and then $300+ for what they called a Win (?) module to get the POS to recognize the key. Then maybe they can find out if there is more "damage".

Glad I found this thread about the TSB, maybe it will save me some $.

Wanna drop a SBC and a Warn OD in my '48 Willys and use it for a DD. At least I could fix it.

FN computers...

I had this happen two nights ago, on my 2008 JK Unlimited, which was made in January 2008.
Of course it did it at night in the Publix parking lot, when it's about 25 degrees. I googled the problem on my phone, and found the TSB, and the one I read mentioned pulling the IOD fuse, with the key removed, waiting 30 seconds, then replacing it. I tried that twice, and no luck.
I had to call my Brother up there, since I had no 10mm or 12mm to disconnect the negative cable.
We did that, and when we reconnected it, the horn chirped, which means the computer thinks the alarm was tripped before the battery was disconnected.
That got it running just like normal, and after 2 days, no signs of it again.
I brought it to the local dealership to have them check it out, since I don't fancy it happening again. Of course, after 3 hours waiting, and likely because I disconnected the battery, no codes were stored in the ECU, and they couldn't duplicate it. Of course if no codes were stored, how did it know to chirp the horn when it was reconnected? Hmmm.....

Anywho, I figure if it does it again, I call the roadside service #, and have them tow it, so they can actually see the failure.
I tried mentioning the TSB to the Service Advisor, but like most, they blow off any suggestion the customer gives, and won't do squat if they can't replicate the issue.

Yes, I'm just guessing that unless it is a customer pay, with out a code to report they would have trouble getting the factory to cover it.... Not that they go out of the way to do anything much for us.....

Mine did this yesterday for the first time. I got a little red light above the temp gage that made me think something was running hot, but a quick check of the owners manual showed it to be the alarm sentry. The jeep would not start or unlock the doors. I disconnected the battery cable for a few seconds and all is fine now. (Other than the fact that it happened at all)

I had a problem today in my 2010 with 13000 miles like this on the way to work this morning I stoped at the gas station to get some things it ran great and when I came out and tried to start it it was dead? I called service and then roadside assistance and they sent a tow truck while I was waiting I remembered to pull the superchips tune and check for any DTC codes I pulled a code that said loss of signal to the security module of coarse they couldn't get to it today so hopefully tomarrow I will find out what the problem is? They even had the balls to say a rental car was no covered and I said WHAT you have got to be kidding I bought a new car thinking it would be dependable I already lost a day of work and 400 bucks! They finally covered the rental car. I was thinking about disconecting the battery I should of tried it I would hate to think how much it would suck if this happend out on the trail?

This is what happened to mine a couple weeks ago. Stuck in Walgreens parking lot for 4 hours. Called roadside #, they came and towed it. 3 days later got it back. Stealership said they replaced the WCM and reprogrammed both my keys. Hasnt happened since. By the way, it was about -cold as shit degrees outside. I didnt pay a dime for any of it. 2008 with 30k

I had the red light over the temp gage light up and my TPS low tire waning was on. As soon as I turned off the jeep everything was dead until I disconnected the battery for a few seconds. After the one time, no more issues, but it was a very cold day when it happened. We don't' have many of those in Southern California.

Does disconnecting the battery get you going each time?

the first couple of times disconnecting the battery would allow it to start. the last time it happened disconnecting the battery didn't work, and i had to leave the jeep at work. the next day the battery was completely dead. after recharging the battery it started right up and has run for a few days just fine. the more i read about it the more everything points to the TIPM.

Have you talked to the dealer yet? Even if you have to pay them, there is a point when you just want your jeep to work.
