SOURCE: 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.

Check the battery Connection. Had the same problem in the 2000. Double check the code and search online.

Diagnostic Fault Code (DTC) P1686 has a generic description of "No SKIM Bus Nessage Received".
Diagnostic Fault Code (DTC) P1687 has a generic description of "No Instrument Cluster Bus Message"

P1688 is either not a valid code for your vehicle, or the manufacturer failed to provide specific information for it.
Basically, what is going on here is that you have a problem in your computer network communication bus. Or to put it more simply, the "phone line" is down. Your computers in your vehicle are having problems talking to each other.

"SKIM" stands for Sentury Key Imobilizer Module (AKA security module). The Instrument cluster and the SKIM are not communicating with the Powertrain Control Module (PCM) for sure, and possibly also not communicating with the Body Control Module (BCM). There may also be problems with other modules that share the same data lines.
This MUST be diagnosed with a scan tool that can access the entire computer network. You must find out which modules can communicate with the scanner and which ones cannot. This is necessary to determine the possible location of the fault.

I have a 1999 Jeep Grand Cherokee limited,V8 Quadra-trac which dies on the road; dash gauges drop; "no key" lite displays on dash. Restarts after cools. Two codes P 0443 and 0308 are showing? help


code p 0443 refers to evaporative emission (EVAP) canister purge valve ---circuit malfunction====causes ---wiring--- EVAP canister purge valve ---ECM
code p0308 refers to cylinder 8 ---misfire detected ====causes ---engine mechanical fault ---wiring----ignition/ fuel system--- injector---ECT/MAF sensor---ECM
I am thinking here that it restarts , not after cooling , but after the vacuum in the fuel tank has lessened and allowed fuel to be pumped to the injectors and the fuel pressure is re-established
if that is the case then a weak injector or partially blocked injector will misfire under those conditions
I would fix the purge valve so that the tank vents properly and the rest may go away

DTC's P1686 P1687


Code 1687 means the computer lost power, probably when you disconnected the battery. Code 1686 means the computer is not talking to the instrument panel.
It could be the cluster or a wiring problem. Since you disconnected the battery, the computer may have to re-learn its parameters to know what the base idle should be. You may have to try to drive it a few miles.

P1698 0n a 1999 jeep grand cherokee,, reset so the engine light is ,, dont pop back on agin untill u shut it if and start it agin, then it comes back on..p1698


Alot of times, this concern has to do with the solder joints on the Cluster. If you take it out and resolder those joints or have them resoldered by someone else, it might just fix your problem. Especially, if this code is accompanied by intermittent gauges and cluster operation.

With a code reader connected to the DTC connection, are there any trouble codes stored? Is there an engine light lit? You will need a code reader to at least start a diagnosis and also a fuel pressure gauge.

1999 jeep showing code p1686


P1686 is a SKIM (Sentry Key Immobilizer Module) no signal code. The keys have tiny chips in them that have to match the SKIM module for that vehicle, if they dont match then the engine will stop running after a few seconds. This is to keep theives from making a key and driving away with you vehicle.
First of all, do you have 2 keys? If so try the other one, if it works, then the other sentry key (the one that didn't work before) has bit the dust. If both do not work and both seem to have same symptoms, then it is quite possibly the module under the sterering wheel cover attached to back of ignition switch which reads the sentry key and if it gets signal from sentry key, then it sends a signal to pcm allowing start up to complete with no shutdown. If this unit is bad, unfortunuately just replacing it is no help, because after replacement a DEALER must then program both the unit and your keys. Make sure you give the dealer both keys, as both have to be reprogrammed to the new unit, if only one is done, the other will not work.
