Saab Code Retrieval
Accessing Diagnostic Trouble
Codes
Using Check Engine Lamp
(1988-92 LH 2.4, 2.4.1 & 2.4.2) Read the following procedure carefully before turning ignition on.
On 900 models, use a switched jumper lead No. 8393886 to ground No.
3 pin in the three-pin test connector located on the right side of
engine compartment.
On 9000 models, use a switched jumper lead to ground the single pin
socket on the test box located on the left side of engine compartment.
On all models, turn ignition on. The check engine will come on. Turn
the jumper lead switch on (grounding ECU pin 16). The check engine
light will now go out. Watch the check engine light carefully. After
approximately 2.5 seconds, the check engine light will flash briefly,
signifying that the first diagnostic trouble code will be displayed.
Immediately turn the jumper lead switch off as soon as the check engine
light has flashed. The first error DTC’s will now be displayed by
a series of short flashes of the check engine light. The error DTC
starts and ends with a long flash of the light. These long flashes
are not part of the DTC, but indicate the beginning and end of the
DTC.
If the test is run with the engine off, DTC 12231 (no RPM signal)
will be the first DTC displayed. As soon as this DTC is displayed,
turn the ignition key to the Start position and hold it there until
the ECU acknowledges by flashing the check engine light. The signal
is being generated. At this point, let the ignition key return to
the Run position so the next DTC can be displayed. With the jumper
lead switch set to off, the same DTC will flash repeatedly. Any additional
DTC’s cannot be displayed until the jumper lead switch has been operated
as follows: Turn the jumper lead switch on. After a short flash of
the check engine light, turn the jumper lead switch off. The next
DTC (if any) will then be displayed.
Repeat this procedure to display a third stored DTC, if any. If a
third fault has not been detected, or all faults have been corrected,
the system will indicate this by a continuous series of long flashes
of the check engine light, or by displaying DTC 12444. 9. To display
the DTC’s again, starting from the first DTC, proceed as follows:
Turn the jumper lead switch on. After two short flashes of the check
engine light, immediately turn the jumper lead switch off. The DTC
for the first fault will now be displayed.
Using LH System Tester
( 1985-92 2.2 LH & 1988-92 2.4 LH) Prior to connecting tester, clean battery terminals to ensure that
the power supply lead clips make a satisfactory contact. Always connect
power supply lead to the tester first and battery last. 1. Remove
cover on left hand side over space behind false bulkhead panel. 2.
On models equipped with anti-lock brake system (ABS), remove ABS ECU
and bracket. 3. On all models, connect test lead between vehicle ECU
and wiring harness. Use a couple of suitable ties to hold ECU and
test connector together. Connect power supply lead to tester and to
prevent it from being pinched, run it between door and body where
there is a break in the seal. Connect tester leads to battery, negative
terminal first, then the positive terminal. Select “TEST MODE” feature
on LH system tester and read any diagnostic trouble codes stored in
ECU memory.
Using ISAT System Tester
(1990-93 LH 2.4 & 2.4.3,1993-95 MOTRIONIC ENGINE MANAGEMENT SYSTEM,
1994-95 MOTRONIC2.8.1 & 2.10-2, DI/APC & EZK IGNITION SYSTEMS) Connect SAAB ISAT tester, or equivalent, to the diagnostic connector
located under the right hand rear seat on 900 models, or under right
hand front seat on 9000 models, per manufacturers’ instructions. Never
unplug connector from ECU or disconnect either of the battery leads
before faults have been transferred to tester.
Clearing Trouble Codes
To clear DTC’s from check engine lamp, proceed as follows:- Turn the jumper lead switch on.
- After three short flashes of the check engine light, turn the
jumper lead switch off.
- The check engine light will now either flash in a continuous series
of long flashes or display DTC 12444, indicating that the contents
of the system’s memory has been erased. After diagnostic trouble
codes have been transferred from ECU memory to the LH system tester,
DTC’s will be cleared from ECU memory.
To clear DTC’s when using SAAB ISAT tester, or equivalent, follow
tool manufacturer’s instructions.
