NOTE: Ignition checks are divided according to fuel system.
SPARK TEST
1) Using an ohmmeter, check resistance of each spark plug
wire. See HIGH TENSION WIRE RESISTANCE table. Check for a strong Blue
spark at coil wire and at each spark plug wire by holding wire
terminal 5/16" from ground while cranking engine.
2) Disconnect and inspect all related ignition system
connectors and harness. Clean or repair if necessary. If related
connectors and harness are okay, remove negative battery cable.
Disconnect secondary and primary leads from ignition coil.
3) Using ohmmeter, check primary resistance between primary
terminals of coil. Check secondary resistance between coil secondary
terminal and primary positive terminal. Replace coil if readings are
not within specifications. See IGNITION COIL RESISTANCE table.

(1) - Ignition coil pack, new for 1993, is located on
left side of cylinder head. When ignition coil is
triggered, spark is supplied to 2 spark plugs at
one time. One spark plug fires during compression
stroke and the other plug fires during exhaust
stroke (waste spark). Ignition coil specifications
are not available from manufacturer.ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ DISTRIBUTOR
Hall Effect Sender
1) Remove coil secondary wire and attach to ground.
Disconnect Hall Effect sender harness connector at distributor. Using
an LED Test Light (US 1115), check for voltage between outer terminals
of connector. See Figs. 2 and 3. With ignition on, light should be on.
If light is on, go to next step. If light is not on, check wiring for
short or open circuit. If wiring is okay, replace ignition control
unit.
2) Reconnect Hall Effect sender harness connector. Pull back
Hall Effect sender boot to expose contact terminals. Connect LED Test
Light (US 1115) probe to center contact and battery positive terminal.
See Fig. 2. Observe test light while cranking engine. If test light
blinks, Hall Effect sender is okay. If light does not blink, replace
Hall Effect sender.Fig. 2: Testing Hall Effect Sender (Typical)

GENERAL INFORMATION
Gear Tooth Contact Patterns
* PLEASE READ THIS FIRST *
The following article is for GENERAL INFORMATION purposes
only. Information does not SPECIFICALLY apply to all years, makes and
models, but is to be used as a general reference guide.
INSPECTION
PRELIMINARY INSPECTION
Wipe lubricant from internal parts. Rotate gears and inspect
for wear or damage. Mount dial indicator to housing, and check
backlash at several points around ring gear. Backlash must be within
specifications at all points. If no defects are found, check gear
tooth contact pattern.
GEAR TOOTH CONTACT PATTERN
NOTE: Drive pattern should be well centered on ring gear teeth.
Coast pattern should be centered, but may be slightly toward
toe of ring gear teeth.
1) Paint ring gear teeth with marking compound. Wrap cloth or
rope around drive pinion flange to act as brake. Rotate ring gear
until clear tooth contact pattern is obtained.
2) Contact pattern will indicate whether correct pinion
bearing mounting shim has been installed and if drive gear backlash
has been set properly. Backlash between drive gear and pinion must be
maintained within specified limits, until correct tooth pattern is
obtained.

INTRODUCTION
PRELIMINARY INFORMATION
Before diagnosing symptoms or intermittent faults, perform
steps in the F - BASIC TESTING article in this section. Use this
article to diagnose driveability problems existing when a hard fault
code is not present or vehicle is not equipped with a self-diagnostic
system.
NOTE: Some driveability problems may have been corrected by
manufacturer with a revised computer calibration chip or
computer control unit. Check with manufacturer for latest
chip or computer application.
Symptom checks can direct the technician to malfunctioning
component(s) for further diagnosis. A symptom should lead to a
specific component, system test or an adjustment.
Use intermittent test procedures to locate driveability
problems that DO NOT occur when the vehicle is being tested. These
test procedures should also be used if a soft (intermittent) trouble
code was present, but no problem was found during self-diagnostic
testing.
NOTE: For specific test procedures, see the I - SYS/COMP TESTS
article in this section. For adjustment procedures, see the
appropriate D - ADJUSTMENTS article. For Engine Performance
related specifications, see appropriate C - SPECIFICATIONS
article in this section. See the following menus:

FUEL & TEMPERATURE GAUGE TEST
NOTE: Volkswagen Tester (VW 1301) is required for resistance
tests. Tester settings are numerical. Settings do not
indicate resistance in ohms. Manufacturer does not supply
resistance values in ohms.
1) Disconnect wire from fuel tank or temperature sending
unit. Connect VW Tester (VW 1301) between wire and ground. Turn
ignition on and allow 2 minutes for gauge reading to stabilize. Use
FUEL GAUGE TESTING or TEMPERATURE GAUGE TESTING table to compare gauge
reading. Gauge should be within one pointer width of specification.
2) If gauge needle does not move, check continuity between
sender wire and gauge. If needle moves but does not match
specifications, replace gauge. If gauge works correctly with tester
but not sending unit, replace sending unit.
