The on off on off on method worked great on older chrysler vehicles, but its not reliable on the OBD2 systems.

all vehicles sold in the us as of 1996 are OBD2 compliant "on board diagnostics second generation" this is a universal system across all vehicles.

take your vehicle to your local parts store and ask them to scan it for you, most part stores wont even charge for the quick scan, dont let them erase the codes because there is other information in the system that will be useful for diagnostics.

get the code list and drop me a line and i will help you out.

1998 grand Cherokee 5.2 engine starts good and idles fine but vehicle will not exceed 100 km an hour

The ignition module will be suspect as well as the engine sensors. Use a code reader or have a diagnostic test done to pinpoint the cause.

1998 Jeep cherokee 4x4 4.0L turn's over will not start.

You need to connecth the car computer to a code reader. In return the code reader will give you error codes that tell you what is wron with the car.
If you have tested all the rest, it is probably a problem with the car computer control module.

Do it Yourself: Reprogramming the Remote Keyless Entry (RKE)

Normal 0 21 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabla normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Jeep Grand Cherokee Alarm System (1993-1998)

I would try reprogramming the Remote Keyless Entry (RKE) transmitters before looking for anything else. Make sure the batteries in the RKE transmitters are good and replace them if in doubt. Here's the procedure for programming the RKE transmitters.

Up to 4 Transmitter Identification Codes (TIC's) can be programmed into the receiver at any given time.

1. Open the driver's door of the vehicle. Leave it open through the programming procedure.
2. Move the mechanical door lock lever to the LOCK position.
3. Insert the ignition key and turn it to the RUN position.
4. Turn the ignition to the RUN position. Within 20 seconds, aim a transmitter at the receiver dome and press the lock button, for at least 5 seconds. Once the receiver accepts the programming code the driver's door will unlock.
5. Once the first transmitter has been programmed, additional transmitters (up to 4) may be programmed into the receiver. Within 20 seconds of the previous transmitter programming, move the mechanical door lock lever to the Lock position. Aim another transmitter at the receiver dome and press the LOCK button for at least 5 seconds. The door lock will cycle again.
6. To lock the programmed codes into the receiver, the ignition must be turned off and back on within 20 seconds after programming the last transmitter's code. At that time, all previous codes are erased from the module.

If the alarm still doesn't work correctly, you probably have a bad Alarm Module. If you wanna download this procedure, clic the image.


Enjoy Jeep.

Jeep Grand Cherokee Limited P0700 diagnostic problem

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.
