Volkswagen Pin Voltage Charts
Corrado SLC
INTRODUCTION
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at ECU/ECM determines whether ECU/ECM is
receiving and transmitting proper voltage signals. Charts may also
help determine if ECU/ECM harness has an electrical short or open.
NOTE: Unless stated otherwise in testing procedures, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. Voltage readings may vary
slightly due to battery condition or charging rate.

Volkswagen Maintenance Reminder Light Reset Procedures
EGR MAINTENANCE LIGHT (IF EQUIPPED)
EGR light comes on at 15,000 mile intervals to indicate EGR
servicing is required. After checking EGR system, reset mileage
counter. See RESETTING MILEAGE COUNTER.
OXYGEN SENSOR WARNING LIGHT (IF EQUIPPED)
Oxygen sensor (OXS) light comes on at 30,000 mile intervals
to indicate oxygen sensor replacement. After installing new sensor,
reset mileage counter. See RESETTING MILEAGE COUNTER.
RESETTING MILEAGE COUNTER (IF EQUIPPED)
1) On some Rabbit and Pickup models, remove instrument panel
cover plate. Reach into opening at top left corner of speedometer and
pull release arm to reset counter. See Fig. 1. Left arm resets EGR
counter, right arm resets oxygen sensor.
2) On Vanagon models, locate mileage counter under spare tire
or under driver's floorboard (in-line with speedometer cable). Using a
pointed instrument, depress reset button. Ensure light is out.
3) On all other models, locate mileage counter (in-line with
speedometer cable) and push White reset button. See Fig. 1. Ensure
light is out.Fig. 1: Resetting Mileage Counters

negative battery cable. Remove luggage compartment floor covering and
fuel pump access cover. Disconnect wiring harness and fuel lines from
fuel pump.
2) Using Wrench (3217), loosen fuel pump screw cap. Remove
flange and sealing ring from fuel tank opening. Loosen fuel pump by
twisting it to left. Remove fuel pump from fuel tank.
3) When installing fuel pump, ensure that fuel gauge sending
unit is not bent. Sending unit must be installed with a frontal angle
of 5 degrees. Align mark on flange with fuel tank. To complete
installation, reverse removal procedure.
FUEL PUMP CHECK VALVE
FUEL RAIL & INJECTORS
Removal & Installation (Corrado SLC)
1) Remove ignition wires. Remove hose from mass airflow
sensor. Disconnect hose to fuel evaporative (frequency) solenoid valve
at throttle body.
2) Disconnect throttle position sensor and idle air control
valve. Disconnect accelerator cable from throttle body. Disconnect and
plug coolant hoses at throttle body.
3) Disconnect hose from air intake heated tube. Detach fuel
lines at cylinder head cover and remove from fuel rail. Disconnect
vacuum hose from fuel pressure regulator. Remove upper intake
manifold.
4) With upper intake manifold removed, disconnect wiring
harness from fuel injector(s). Pry off retaining clip(s) from
injector(s). To install injectors, lubricate "O" rings with fuel. To
complete installation, reverse removal procedure.
