If you want "TUNE-UP" type information, see D - ADJUSTMENTS
for the adjustment procedures. If you are familiar with the
procedures, but need a quick way to find the specification, go to C -
TUNE-UP SPECS or C - SPECIFICATIONS for the specifications pertaining
to the vehicle.
When diagnosing driveability problems, first go to F - BASIC
TESTING. This article is here to help eliminate wasted diagnostic
time. If the basic systems are working properly, go to G - TESTS W/
CODES.
If the vehicle still is having a driveability problem or if
the vehicle has no self-diagnostic system, go to H - TESTS W/O CODES.
This article will help you diagnose the problem by symptom, locate the
symptom exhibited by the vehicle, and inspect or test the items which
may be causing the problem.
After finding which specific system or component requires
testing, use the I - SYS/COMP TESTS article to tests the systems and
components. We have also included (when available) pin voltage charts
and sensor range charts. These can be found in J - PIN VOLTAGE CHARTS
and K - SENSOR RANGE CHARTS.
Also included in this section are wiring diagrams and vacuum
diagrams. These can be found in L - WIRING DIAGRAMS and M - VACUUM
DIAGRAMS.
When all diagnostic tests have been performed and the problem
has been discovered, it may be necessary to replace or overhaul the
defective part. This information can be found in
N - REMOVE/INSTALL/OHAUL.
The content of each of these articles is outlined below. As a
summary of the driveability diagnosis, see ROUTINE OUTLINE in this
article.
A - ENGINE/VIN ID
This article shows how to identify the model and engine by
its Vehicle Identification Number (VIN). A model coverage chart shows
each model and engine, the fuel system, ignition system and engine
code. The engine serial number locations are also included in this
article.
B - EMISSION APPLICATION
These charts identify the emission systems and sub-systems
applicable to each model and engine combination.
C - TUNE-UP SPECS
This is a collection of quick-reference type specifications.
This article is helpful when you are familiar with proper adjustment
procedures and only need specifications. Included in this section are:
* Battery specifications.
* Fluid capacities.

1) Disconnect throttle valve switch connector. With ohmmeter
set on 200-ohm scale, attach probes to male terminals. Ensure throttle
valve switch is completely closed. With throttle valve closed, meter
reading should be zero.
2) Position throttle valve to 1/2 open position. Ohmmeter
reading should be infinite. Position throttle to fully open position.
Ohmmeter reading should be zero. If any reading is incorrect, perform
throttle valve switch adjustment. See D - ADJUSTMENTS article.
3) If correct specifications cannot be obtained, check
throttle shaft play, accelerator cable adjustment and throttle switch
actuating cam. If okay, replace throttle valve switch.
RELAYS
FUEL PUMP RELAY (CABRIOLET, GOLF GL/GTI & JETTA)
1) Ensure fuel pump fuse (No. 5) is okay. Remove fuel pump
relay (No. 2) from fuse/relay panel. See Fig. 6. With ignition on,
check for battery voltage between the following locations:
* Terminal No. 2 and ground
* Terminals No. 2 and No. 1
* Terminal No. 4 and No. 1
If voltage is not present, repair wiring and recheck fuel
pump operation.
2) With battery voltage present between terminal No. 1 and
terminal No. 5, lightly touch middle wire of ignition distributor
harness connector to ground. If voltage drops, replace fuel pump relay
and check Hall Effect sender.
3) If voltage does not drop, check Hall Effect sender. See
HALL EFFECT SENDER in F - BASIC TESTING ARTICLE. For fuel pump and
fuse number/location, see FUEL PUMP RELAY & FUSE NUMBER TABLE.Fig. 6: Identifying Fuse/Relay Panel (All Models Except Vanagon)

FUEL PUMP RELAY (FOX)
1) Ensure fuel pump fuse (No. 13) is okay. Remove fuel pump
relay. Note terminals numbers molded on fuse/relay panel. With
ignition on, check for battery voltage between the following
locations:
* Terminal No. 46 and ground
* Terminal No. 48 and ground
2) If voltage is not present, current is not reaching the
relay. Repair wiring. Check fuel pump operation. If voltage is
present, check for battery voltage between the following locations:
* Terminals No. 48 and No. 50
* Terminals No. 46 and No. 50
If voltage is not present, terminal No. 50 (ground circuit)
is open. Repair wiring. Check fuel pump operation.
3) If voltage is present, check for battery voltage between
terminals No. 50 and No. 51. If voltage is not present, the ignition
signal is not reaching fuel pump relay. Repair wiring. Check fuel pump
operation.
4) If no faults can be found and fuel pump operates when
relay is by-passed, replace fuel pump relay. For fuel pump and fuse
number/location, see FUEL PUMP RELAY & FUSE NUMBER table.
FUEL PUMP RELAY (CORRADO)
1) Ensure fuel pump fuse No. 18 is okay. Remove fuel pump
relay No. 12 from fuse/relay panel. See Fig. 6. With ignition on,
check for battery voltage between the following locations:
* Terminal No. 6 and ground.
* Terminal No. 2 and ground.
* Terminals No. 6 and No. 4.
2) If battery voltage is not present, check wiring and repair
as needed. Check fuel pump operation. With ignition off, connect
voltmeter between terminals No. 2 and No. 3. Turn ignition on. Voltage
should be present for one second. If voltage is not present for one
second, check wiring to ECU or replace ECU. Check fuel pump relay
operation. For fuel pump and fuse number/location, see FUEL PUMP RELAY
& FUSE NUMBER table.
FUEL PUMP RELAY (VANAGON)
1) Check terminal No. 30 and terminal No. 86 of fuel pump
relay for battery voltage. If battery voltage is not present, check
circuit for short or open circuit.
2) If battery voltage is present, remove relay and attach
ohmmeter probe to relay box terminal No. 85. Attach other probe to

articles, there will be a COMPONENT LOCATION MENU title in
the article main menu. These articles will also have the
original legend available on the first graphic.Fig. 1: Identifying Tie-Off Symbols
4) If the wires are not drawn all the way to another
component (across several pages), a reference will tell you their
final destination.
5) Again, use the legend on the first page of the wiring
diagram to determine the grid number and letter of the referenced
component. You can then turn directly to it without tracing wires
across several pages.
6) The symbols shown in Fig. 1 are called tie-offs. The first
tie-off shown indicates that the circuit goes to the temperature
sensor, and is also a ground circuit.
7) The second symbol indicates that the circuit goes to a
battery positive parallel circuit. The third symbol leads to a
particular component and the location is also given.
8) The lines shown in Fig. 2 are called options. Which path
or option to take depends on what engine or systems the vehicle has.Fig. 2: Identifying Option Symbols
