positive lead to anti-theft control module 10-pin wiring harness
connector terminal No. "7" (Red/Yellow wire for Corrado SLC;
Yellow/Red wire for Passat). Insert key in driver's door lock. Turn
key against stop and hold momentarily. Voltmeter should register 12
volts. Repeat procedure for passengers door. If voltage is correct for
each door, go to next step. If voltage is correct, repair door switch
or open circuit.
3) Door Lock Switch Check
Connect voltmeter negative lead to ground. Connect positive
lead to anti-theft control module 10-pin wiring harness connector
terminal No. "6" (Red/Black wire). Insert key in driver's door lock.
Turn key against stop and hold momentarily. Voltmeter should register
12 volts. Repeat procedure for passengers door. If voltage is correct
for each door, replace control module. If voltage is not correct,
repair door switch or open circuit.
ALARM HORN INOPERATIVE
1) Alarm Horn Check
Ensure battery is fully charged. 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) Connect ohmmeter negative lead to ground. Connect positive
lead to anti-theft control module 6-pin wiring harness connector
terminal No. "4" (Black/Yellow wire). If continuity is present,
replace anti-theft control module. If continuity is not present, check
for open circuit and repair as necessary. If circuit is okay, replace
alarm horn.
LIGHTS DO NOT FLASH
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) Connect voltmeter negative lead to ground. Connect
positive lead to anti-theft control module 6-pin wiring harness
connector terminal No. "1" (Black/White wire for Corrado SLC; Black
Yellow wire for Passat). Turn emergency flashers on. When lights flash

1992-93 BRAKES
Volkswagen Disc & Drum
Corrado SLC
DESCRIPTION
All models are equipped with front disc brakes. Rear brakes
are either disc or drum. Parking brake acts on rear brakes and is
cable-actuated. All models use pressure regulator between front and
rear brake circuits to avoid rear wheel lock-up during hard braking.
A vacuum power-assist servo is used to ease brake pedal
application. A vacuum check valve, located in vacuum supply hose,
prevents vacuum leakdown when engine is off.
SERVICING
Manufacturer recommends replacing brake fluid every 2 years.
BLEEDING BRAKE SYSTEM
CAUTION: Ensure fluid level in master cylinder is adequate at all
times during bleeding procedure. Use only DOT 4 brake fluid.
DO NOT use DOT 5 silicone brake fluid.
BLEEDING PROCEDURES
NOTE: Manufacturer recommends bleeding brake system using Pressure
Bleeder (US 1116). If a pressure bleeder is not available,
use standard bleeding procedure.
1) Exhaust vacuum reserve from power unit by depressing brake
pedal several times. On ABS-equipped vehicles, depress brake pedal at
least 20 times to relieve system pressure.
2) On all vehicles, fill master cylinder with clean brake
fluid. If master cylinder was replaced, bleed master cylinder before
bleeding wheel calipers. Connect bleeder hose to appropriate caliper
bleeder valve. See BRAKE BLEEDING SEQUENCE table.
