2000 Grand Cherokee - New computer - P1685
 

I have been having issues with my 2000 Grand Cherokee V6 that several
shops advised would be replaced by installing a new computer. I was
having sporadic cylinder misfires, odd stalls, and a weird one where
I
would turn the key to the off position and remove the key and the
jeep
would keep running.

Anyways, I bought a new computer from a salvage yard and just
finished
installing it. THe Jeep starts up great, but then dies out with a
P1685 error. I know that that means SKIM error and that obviously
the
new computer doesn't recognize the key I use.


The question I have now is, what next? Do I have to take it to the
Jeep dealer to have the computer programmed? Or can I take it to my
local guy that I trust?


Any help is much appreiciated.


Thanks.

Not 100% on this. I believe it takes the dealership programmer to reset
the SKIM code.

That sucks. The closest dealer (by far) to me wanted to charge $1200
to replace the ECM in the first place which is why I went to a salvage
yard. I wonder if they'll still try to charge me the full amount if I
have my car towed in.

From what I read, you should get a
P0513 Invalid SKIM Key
or
P0633 SKIM Key Not Programmed

Sure you have every wire hooked back up with no bent pins?

If there was no feed you would get
P1686 No SKIM BUS Messages Received



Be Careful.. start it with the wrong key six times
and it will require a trip to the dealer.

I wonder if you have a simple steel key (no skim)
AKA, a Valet key, you should be able to get to the dealer.
(I would call to confirm this)



This might help.

801505 - POWERTRAIN CONTROL MODULE INITIALIZATION

Date: 03/02/05

Model Year(s): 1999-2004

Description: NOTE: The model years and vehicles above must
be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply. When a
Powertrain Control Module (PCM) is replaced on vehicles
equipped with the Sentry KeyT Theft Deterrent System, it
must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by
using the DRBIII® or StarSCANT Scan Tool to enter a PIN number.

When the PIN number is not available from the vehicle owner
or a Chrysler Group Scan Tool(s) is not available this can
be accomplished by writing the Vehicle Identification Number
(VIN) into the PCM using an after-market scan tool with a
"VIN Write Function". More information is available from
the scan tool manufacturer or the Equipment & Tool Institute.

NOTE: After performing this procedure with an after-market
scan tool on vehicles equipped with Chrysler Group's Next
Generation Controller (NGC), Diagnostic Trouble Code (DTC)
"P0633 - SKIM SECRET KEY DATA NOT STORED IN PCM" will be set.
This DTC will not effect vehicle or system performance and
cannot be erased.
