help me plz

 

I'm having a hard time following you but...


When you say "and immo light on dash.", are you saying that the Sentry Key Immobilizer light in the upper left hand side of the instrument cluster is on?


If so, and you do have the Sentry Key Immobilizer System, I'd say that is the root cause of your problems. That light on the instrument cluster is telling you the SKIS system has either detected a malfunction or is inoperative and will not allow starting the engine.


If you are getting a "NO BUS' in your odometer the Sentry Key Immobilizer Module may be corrupting the CCD Bus.


Read through this data to learn more abut the system.

 

hi
i have done these:
1.check wire and connectors
2.replace cps
3.check all fuse and relay
4.check key & immobilizer
but it has previous problems,such as:
1.no Gage
2.no bus
3.immo's light is on yet
4.no connect to pcm
plz help& advice me

 

It would appear that your Sentry Key Immobilizer System (SKIS) is causing the problem.


Access the Sentry Key Immobilizer Module (SKIM) and unplug the electrical connector. Turn the ignition switch to ON/RUN and see if the instruments come back to life. If so, I would suspect that the SKIM is corrupting the CCD Bus. Your engine won't run with the SKIM disconnected.


Below are pics of the SKIM and its connector, and instructions on how to get at it.


The problem for you is if it is the SKIM you'll need a new one and you'll need to have the PCM programmed to the new SKIM.


Another option is to leave the SKIM disconnected and get another PCM that is NOT programmed for SKIS. Or, remove your PCM and send it to a shop that can de-program it. Then you can operate your Jeep without SKIS.


SKIM Installed:





The SKIM itself:





SKIM Connector unplugged:





Instructions: Remove the battery negative post connector during this process then reconnect to test.

 

tnx.
could be decode pcm?
how can i file flash pcm?
i don't have access here

 

You'll have to remove your PCM and mail it to a shop that can do the job. You may have to send it to the U.S. to get it done (?). Check the internet for a PCM repair shop.
