GENERAL INFORMATION
DaimlerChrysler Computer Relearn Procedures
INTRODUCTION
Vehicles equipped with engine or transmission/transaxle
computers may require a computer relearn procedure after the vehicle
battery is disconnected. Vehicle computers memorize and store vehicle
operation patterns for optimum driveability and performance. When the
vehicle battery is disconnected, this memory is lost, resulting in a
driveability problem. Depending on the vehicle and how it is equipped,
the following driveability problems may exist:
* Rough or unstable idle.
* Hesitation or stumble.
* Rich or lean running.
* Poor fuel mileage.
* Harsh or poor transmission/transaxle shift quality.
Default data is used until NEW data from each key start is
stored. As the computer restores its memory from each new key start,
driveability is restored.
Driveability problems may occur during the computer relearn
stage. To accelerate computer relearn process after battery removal
and installation, specified computer relearn procedures should be
performed. See appropriate procedures under specified manufacturer.
COMPUTER RELEARN PROCEDURES
ALL MODELS
NOTE: Read all procedures listed to determine why each procedure is
to be performed before proceeding.
Vehicle Driveability Computer Relearn Procedure
Manufacturer does not provide a specified computer relearn
procedure for obtaining proper driveability. If vehicle battery was
disconnected or Powertrain Control Module (PCM) was replaced, driving
the vehicle will enable the PCM to perform a computer relearn
procedure for obtaining proper driveability. Inform customer that
driveability may differ from what they are accustomed to until the PCM
completes the computer relearn procedure.
NOTE: If Powertrain Control Module (PCM) was replaced, the correct
vehicle mileage and Vehicle Identification Number (VIN) must
be programmed into the PCM to prevent Diagnostic Trouble
Codes (DTCs) from being set in the Anti-Lock Brake System
(ABS) module and Supplemental Restraint System (SRS) module\
.
To program PCM and clear DTCs from ABS and SRS modules,
proceed to appropriate procedure listed. If replacing
Powertrain Control Module (PCM) on models equipped with a
Smart Key Immobilizer Module (SKIM), the secret key data must\
also be updated to enable engine starting. To update secret
key data, proceed to appropriate procedure listed.
Programming PCM & Clearing DTCs From ABS & SRS Modules
Connect scan tool to Data Link Connector (DLC) below driver's\
side of instrument panel. Using scan tool, enter correct VIN and
mileage into PCM. Using scan tool manufacturer's instructions, clear

Smart Key Immobilizer Module (SKIM) to the PCM.
NOTE: If 3 attempts are made to enter the SECURED ACCESS MODE using
the incorrect Personal Identification Number (PIN), the
SECURED ACCESS MODE will be locked out for one hour. To exit
this locked-out mode, leave ignition switch in the ON
position for one hour with all accessories turned off. It may
be necessary to monitor battery state and connect a battery
charger.
