GENERAL INFORMATION
Computer Relearn Procedures
All Models
* PLEASE READ THIS FIRST *
The following general procedures are to be used if
driveability problems are encountered after power loss or battery has
been disconnected. These procedures may provide an aid in eliminating
these problems.
To reduce the possibility of complaints, after any service
which requires battery power to be disconnected, vehicle should be
road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may
require a relearn procedure after vehicle battery is disconnected.
Many vehicle computers memorize and store vehicle operation patterns
for optimum driveability and performance. When vehicle battery is
disconnected, this memory is lost. The computer will use default data
until new data from each key start is stored. As computer memorizes
vehicle operation for each new key start, driveability is restored.
Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during
relearn stage because vehicle acts differently then before being
serviced. Depending on type and make of vehicle and how it is
equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality
* Rough Or Unstable Idle
* Hesitation Or Stumble
* Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number
of drive cycles have been memorized. To reduce the possibility of
complaints, after any service which requires battery power to be
disconnected, vehicle should be road tested. If a specific relearn
procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select

"D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle
shifts into top gear.
* Cruise at light to medium throttle.
* Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally.
* Process may be repeated as necessary.
Manual Transmission
* Place transmission in Neutral position.
* Ensure emergency brake has been set and all accessories
are turned off.
* Start engine and bring to normal operating temperature.
* Allow vehicle to idle in Neutral for one minute.
* Initial relearn is complete: process will be completed during
normal driving.
Some manufacturers identify a specific relearn procedure
which will help establish suitable driveability during relearn stage.
These procedures are especially important if vehicle is equipped with
and electronically controlled automatic transmission or transaxle.
Always complete procedure before returning vehicle to customer.

1993 ACCESSORIES & EQUIPMENT
Volkswagen Cruise Control Systems
Volkswagen; Corrado SLC, EuroVan, Passat
DESCRIPTION & OPERATION
The cruise control system allows driver to maintain a
constant cruising speed above 22 MPH without depressing the
accelerator pedal. The cruise control system consists of a vacuum
pump, vacuum servo unit, vent valves and a control module. See Fig. 1
and 2.
The cruise control system is operated by placing RES/ON/OFF switch in
the ON position. Accelerate to desired speed and press the SET button.
This sets the cruising speed and stores it in memory. Pushing the SET
button again will increase the previous set speed until the button is
released.
Cruise control system will disengage temporarily when the
brake or clutch pedal is depressed. To reactivate system, slide the
RES/ON/OFF button to RESUME. The vehicle will automatically accelerate
to the previous set speed. To erased set speed from memory, slide the
RES/ON/OFF button to OFF.
WARNING: DO NOT shift into Neutral when cruise control system is
switched on.Fig. 1: Identifying Cruise Control System Components
