Saab: 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 tool No. 8393886, or equivalent, to ground No. 3 pin in three-pin test connector located on RH side of engine compartment.
On 9000 models, use a switched jumper lead to ground single pin socket on test box located on LH side of engine compartment.
On all models, turn ignition On. The Check Engine lamp will light.
Turn jumper lead switch on (grounding ECU pin 16). The Check Engine lamp will now go out.
Watch Check Engine lamp carefully. After approximately 2.5 seconds, it will flash briefly, signifying that first DTC will be displayed. Immediately turn jumper lead switch off as soon as lamp has flashed.
First error DTCs will now be displayed by a series of short lamp flashes. Error DTC starts and ends with a long flash. These long flashes are not part of DTC, but indicate beginning and end of DTC.
If test is run with engine off, DTC 12231 (no RPM signal) will be first DTC displayed. As soon as this DTC is displayed, turn ignition to Start position and hold it there until ECU acknowledges by flashing Check Engine lamp. The signal is being generated. At this point, let ignition key return to Run position so next DTC can be displayed.
With jumper lead switch set to off, same DTC will flash repeatedly. Any additional DTCs cannot be displayed until jumper lead switch has been operated as follows:
Turn jumper lead switch on.
After a short Check Engine lamp flash, turn 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, system will indicate this by a continuous series of long Check Engine lamp flashes, or by displaying DTC 12444.
To display DTCs again, starting from first DTC, proceed as follows:
Turn jumper lead switch on.
After two short Check Engine lamp flashes, immediately turn 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)
Clean battery terminals prior to connecting tester to ensure that the power supply lead clips make a satisfactory contact. Always connect power supply lead to the tester first and battery last.
Remove cover on LH side over space behind false bulkhead panel.
On models equipped with anti-lock brake system (ABS), remove ABS ECU and bracket.
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 DTCs stored in ECU memory.
Using ISAT System Tester (1990–93 LH 2.4 & 2.4.2, 1993–95 Trionic Engine Management System, 1994–95 Motronic 2.8.1 & 2.10.2, DI/APC & EZK Ignition Systems)
Connect SAAB ISAT tester, or equivalent, to the diagnostic connector located under the RH rear seat on 900 models, or under RH front seat on 9000 models, per manufacturer’s instructions. Never unplug connector from ECU or disconnect either of the battery leads before faults have been transferred to tester.
Using ISAT System Tester (1996–01 Motronic 4.1 & 5.2 & Trionic Engine Management Systems)
The new EPROM developed for the ISAT tool uses EPROM, a new command code system. It contains a system of menus in clear text, enabling the user to select the desired command directly on the keypad. The EPROM consists of eight main menus, each with sub-menus.
Connect a suitable ISAT tool to diagnostics socket pin 50, located under the LH side of the instrument panel. To access DTCs, select ‘‘READ FAULT CODES’’ from main menu.
***********************************************************
To clear DTCs from Check Engine lamp, proceed as follows:
Turn jumper lead switch on.
After three short Check Engine lamp flashes, turn jumper lead switch off.
The Check Engine lamp will now either flash in a continuous series of long flashes or display DTC 12444, indicating that contents of system’s memory have been erased.
After DTCs have been transferred from ECU memory to LH system tester, DTCs will be cleared from ECU memory.
To clear DTCs when using SAAB ISAT tester, or equivalent, follow tool manufacturer’s instructions.
