1) Alarm Horn Check
Ensure battery is fully charged and emergency flasher system
is functional. Obtain radio security code. Disconnect battery cable
terminals. Disconnect anti-theft control module 6-pin and 10-pin
wiring harness connector. See ANTI-THEFT CONTROL MODULE LOCATION
table.
2) Reconnect negative battery cable. Connect voltmeter
negative lead to ground. Connect positive lead to anti-theft control
module 6-pin wiring harness connector terminal No. "5" (Red/Green wire
for Corrado SLC; Red/White wire for Passat). Observe voltmeter while
turning ignition to START position. If battery voltage is present, go
to next step. If battery voltage is not present, repair circuit to
ignition switch.
3) Remove ignition key. Disconnect negative battery cable.
Connect ohmmeter negative lead to ground. Connect positive lead to
anti-theft control module 6-pin wiring harness connector terminal No.
"6" (Red/Black wire for Corrado SLC; Violet/Black wire for Passat). If
continuity is present, replace anti-theft control module. If
continuity is not present, check wiring harness to starter for open
circuit.

procedure. Adjust linkage as necessary.
TESTING
VACUUM CHECK
Locate vacuum pump. See Fig. 7 or 8. Remove vacuum line from
vacuum pump. Push vacuum actuator diaphragm inward. Apply brake pedal
by hand until pressure is felt. Release brake pedal. If diaphragm
moves, repair or replace as necessary.

Volkswagen Rear Window Defoggers
Volkswagen; Cabriolet, Corrado SLC, EuroVan,
Fox, Golf, GTI, Jetta, Passat
DESCRIPTION & OPERATION
Ignition must be on for rear window defogger to operate.
Power to control switch is applied through fuse in fuse block. An
indicator light in the control switch comes on when the defogger is
turned on. Control switch also provides power to heating element in
both outside mirrors.
TROUBLE SHOOTING
DEFOGGER DOES NOT WORK
Check for blown fuse, defective defogger switch, open wiring
or poor connections. Check for breaks in rear window defogger grid.
See FILAMENT TEST under TESTING.
INDICATOR LIGHT DOES NOT WORK
Check for burned bulb, blown fuse, open wiring or poor
connection.
TESTING
SYSTEM TEST
Ensure and control switch are okay. Turn ignition and control
switch on. After a few minutes, feel glass for warmth. If glass is not
warm, use a test light to check for battery voltage at grid feed wire.
If no voltage is present, check control switch.
FILAMENT TEST
1) To locate breaks in grid filaments, connect test light
negative lead to ground side of grid. Touch opposite (positive) side
of grid with test light probe. If test light glows, grid line is okay.
Test light will glow dimmer as probe is moved toward ground side of
grid.
2) If test light does not glow, grid line is broken. To
locate break, move probe along grid line toward ground side of heat
grid until test light glows, indicating area of damage.

Volkswagen Power Door Locks
Volkswagen; Corrado SLC, Passat
DESCRIPTION & OPERATION
Power locks are an electronically controlled, vacuum operated
system. Components include bi-pressure pump, tubing and an activator
for each door. See Fig. 1, 2 or 3.
The power lock system operates from either passenger or driver's door
lock. If the key is inserted in either door or trunk lock and held in
the unlock position, all locks will be operated simultaneously. Power
lock system will not operate on door(s) or trunk lid if left
unlatched.Fig. 1: Power Door Lock System Vacuum Diagram &

Volkswagen Basic Diagnostic Procedures
Cabriolet, Corrado SLC, EuroVan, Fox, Golf,
GTI, Jetta, Passat GL, Passat GLX
INTRODUCTION
The following diagnostic steps will help prevent overlooking
a simple problem. This is also where to begin diagnosis for a no-start
condition.
The first step in diagnosing any driveability problem is
verifying the customer's complaint with a test drive under the
conditions the problem reportedly occurred.
Before entering self-diagnostics (if equipped), perform a
careful and complete visual inspection. Most engine control problems
result from mechanical breakdowns, poor electrical connections, or
damaged/misrouted vacuum hoses. Before condemning the computerized
system, perform each test listed in this article.
NOTE: Perform all voltage tests with a Digital Volt-Ohmmeter
(DVOM) with a minimum 10-megohm input impedance, unless
stated otherwise in test procedure.
PRELIMINARY INSPECTION & ADJUSTMENTS
VISUAL INSPECTION
Visually inspect all electrical wiring, looking for chafed,
stretched, cut or pinched wiring. Ensure electrical connectors fit
tightly and are not corroded. Ensure vacuum hoses are properly routed
and are not pinched or cut. See M - VACUUM DIAGRAMS article in this
section to verify routing and connections (if necessary). Inspect air
induction system for possible vacuum leaks.
MECHANICAL INSPECTION
Compression
Check engine mechanical condition with a compression gauge,
vacuum gauge, or an engine analyzer. See engine analyzer manual for
specific instructions.
WARNING: DO NOT use ignition switch during compression tests on fuel
injected vehicles. Use a remote starter to crank engine. Fuel
injectors on many models are triggered by ignition switch
during cranking mode, which can create a fire hazard or
contaminate the engine's oiling system.
