GENERATOR SYSTEM CHECK
When operating normally, the generator indicator lamp
will come on when the ignition switch is in the ON posi-
tion and go out when the engine starts. If the lamp oper-
ates abnormally or if an undercharged or overcharged
battery condition occurs, the following procedure may
be used to diagnose the charging system. Remember
that an undercharged battery is often caused by acces-
sories being left on overnight or by a defective switch
that allows a lamp, such as a trunk or glove box lamp, to
stay on.
Diagnose the generator with the following procedure:
1. Visually check the belt and wiring.
2. With the ignition switch in the ON position and the en-
gine stopped, the charge indicator lamp should be on.
If not, detach the harness at the generator and
ground the ‘‘L’’ terminal in the harness with a fused,
5-ampere jumper lead.
If the lamp lights, replace the generator. Refer to
“Generator” in the On-Vehicle Service section.

If the lamp does not light, locate the open circuit
between the ignition switch and the harness con-
nector. The indicator lamp bulb may be burned out.
3. With the ignition switch in the ON position and the en-
gine running at moderate speed, the charge indicator
lamp should be off. If not, detach the wiring harness
at the generator.

If the lamp goes off, replace the generator. Refer to
“Generator” in the On-Vehicle Service section.

If the lamp stays on, check for a short to ground in
the harness between the connector and the indica-
tor lamp.
Important: Always check the generator for output be-
fore assuming that a grounded ‘‘L’’ terminal circuit has
damaged the regulator. Refer to “Generator” in the Unit
Repair section.

termittent fault will also be erased from memory. If the
fault that caused the DTC to be stored into memory has
been corrected, the Diagnostic Executive will begin to
count the ‘‘warm-up” cycles with no further faults de-
tected, the DTC will automatically be cleared from the
Engine Control Module (ECM) memory.
To clear DTCs, use the diagnostic scan tool.
It can’t cleared DTCs without the diagnostic scan tool.
So you must use the diagnostic scan tool.
Notice: To prevent system damage, the ignition key
must be OFF when disconnecting or reconnecting bat-
tery power.

The power source to the control module. Examples:
fuse, pigtail at battery ECM connectors, etc.

The negative battery cable. (Disconnecting the nega-
tive battery cable will result in the loss of other Euro
On-Board memory data, such as preset radio tuning.)
DTC Modes
On Euro On-Board Diagnostic (EOBD) passenger cars
there are five options available in the scan tool DTC
mode to display the enhanced information available. A
description of the new modes, DTC Info and Specific
DTC, follows. After selecting DTC, the following menu
appears:

DTC Info.

Specific DTC.

Freeze Frame.

Fail Records (not all applications).

Clear Info.
The following is a brief description of each of the sub
menus in DTC Info and Specific DTC. The order in
which they appear here is alphabetical and not neces-
sarily the way they will appear on the scan tool.
DTC Information Mode
Use the DTC info mode to search for a specific type of
stored DTC information. There are seven choices. The
service manual may instruct the technician to test for
DTCs in a certain manner. Always follow published ser-
vice procedures.
To get a complete description of any status, press the
‘‘Enter” key before pressing the desired F-key. For ex-
ample, pressing ‘‘Enter” then an F-key will display a defi-
nition of the abbreviated scan tool status.
DTC Status
This selection will display any DTCs that have not run
during the current ignition cycle or have reported a test
failure during this ignition up to a maximum of 33 DTCs.
DTC tests which run and pass will cause that DTC num-
ber to be removed from the scan tool screen.
Fail This Ign. (Fail This Ignition)
This selection will display all DTCs that have failed dur-
ing the present ignition cycle.
History
This selection will display only DTCs that are stored in
the ECM’s history memory. It will not display Type B
DTCs that have not requested the Malfunction Indicator
Lamp (MIL). It will display all type A, B and E DTCs that
have requested the MIL and have failed within the last
40 warm-up cycles. In addition, it will display all type C
and type D DTCs that have failed within the last 40
warm-up cycles.
Last Test Fail
This selection will display only DTCs that have failed the
last time the test ran. The last test may have run during
a previous ignition cycle if a type A or type B DTC is dis-
played. For type C and type D DTCs, the last failure
must have occurred during the current ignition cycle to
appear as Last Test Fail.
MIL Request
This selection will display only DTCs that are requesting
the MIL. Type C and type D DTCs cannot be displayed
using this option. This selection will report type B and E
DTCs only after the MIL has been requested.
Not Run SCC (Not Run Since Code Clear)
This option will display up to 33 DTCs that have not run
since the DTCs were last cleared. Since the displayed
DTCs have not run, their condition (passing or failing) is
unknown.
Test Fail SCC (Test Failed Since Code
Clear)
This selection will display all active and history DTCs
that have reported a test failure since the last time DTCs
were cleared. DTCs that last failed more than 40 warm-
up cycles before this option is selected will not be dis-
played.
Specific DTC Mode
This mode is used to check the status of individual diag-
nostic tests by DTC number. This selection can be ac-
cessed if a DTC has passed, failed or both. Many EOBD
DTC mode descriptions are possible because of the ex-
tensive amount of information that the diagnostic execu-
tive monitors regarding each test. Some of the many
possible descriptions follow with a brief explanation.
The “F2” key is used, in this mode, to display a descrip-
tion of the DTC. The “Ye s” and “No” keys may also be
used to display more DTC status information. This
selection will only allow entry of DTC numbers that are
supported by the vehicle being tested. If an attempt is,

DIAGNOSTIC INFORMATION AND PROCEDURES
SYSTEM DIAGNOSIS
DIAGNOSTIC AIDS
If an intermittent problem is evident, follow the guide-
lines below.
Preliminary Checks
Before using this section you should have already per-
formed the “Euro On-Board Diagnostic (EOBD) System
Check.”
Perform a thorough visual inspection. This inspection
can often lead to correcting a problem without further
checks and can save valuable time. Inspect for the fol-
lowing conditions:

Engine Control Module (ECM) grounds for being
clean, tight, and in their proper location.

Vacuum hoses for splits, kinks, collapsing and proper
connections as shown on the Vehicle Emission Con-
trol Information label. Inspect thoroughly for any type
of leak or restriction.

Air leaks at the throttle body mounting area and the
intake manifold sealing surfaces.

Ignition wires for cracks, hardness, proper routing,
and carbon tracking.

Wiring for proper connections.

Wiring for pinches or cuts.
Diagnostic Trouble Code Tables
Do not use the Diagnostic Trouble Code (DTC) tables to
try and correct an intermittent fault. The fault must be
present to locate the problem.
Incorrect use of the DTC tables may result in the unnec-
essary replacement of parts.
Faulty Electrical Connections or Wiring
Most intermittent problems are caused by faulty electri-
cal connections or wiring. Perform a careful inspection
of suspect circuits for the following:

Poor mating of the connector halves.

Terminals not fully seated in the connector body.

Improperly formed or damaged terminals. All connec-
tor terminals in a problem circuit should be carefullyinspected, reformed, or replaced to insure contact
tension.

Poor terminal-to-wire connection. This requires re-
moving the terminal from the connector body.
Road Test
If a visual inspection does not find the cause of the prob-
lem, the vehicle can be driven with a voltmeter or a scan
tool connected to a suspected circuit. An abnormal volt-
age or scan tool reading will indicate that the problem is
in that circuit.
If there are no wiring or connector problems found and a
DTC was stored for a circuit having a sensor, except for
DTC P0171 and DTC P0172, replace the sensor.
Intermittent Malfunction Indicator Lamp
(MIL)
An intermittent Malfunction Indicator Lamp(MIL) with no
DTC present may be caused by the following:

Improper installation of electrical options such as
lights, two way radios, sound, or security systems.

MIL driver wire intermittently shorted to ground.
Fuel System
Some intermittent driveability problems can be attrib-
uted to poor fuel quality. If a vehicle is occasionally run-
ning rough, stalling, or otherwise performing badly, ask
the customer about the following fuel buying habits:

Do they always buy from the same source? If so, fuel
quality problems can usually be discounted.

Do they buy their fuel from whichever fuel station that
is advertising the lowest price? If so, check the fuel
tank for signs of debris, water, or other contamina-
tion.
IDLE LEARN PROCEDURE
Whenever the battery cables, the Engine Control Mod-
ule (ECM), or the fuse is disconnected or replaced, the
following idle learn procedure must be performed:
1. Turn the ignition ON for 10 seconds.
2. Turn the ignition OFF for 10 seconds.
