Saab Trouble Codes OBD1

Saab has used the check engine light on the instrument cluster to alert the drive the car has encountered a malfunction of the engine or emission systems. Once activated the check engine light will flash a one or two digit code. Like most pre ODB11 operating systems the first set of blinks will be the first digit of the trouble code, there will be a brief pause as the computer gets ready to blink out the second digit of the trouble code. To activate this code retrieval mode a switched ground wire must be connected to the computer pin # 16. This can be done several different ways but the most common method is locating the diagnostic connector which is near the right side of the engine. 

Once this is completed turn the ignition key to the "on" position. The check engine light will flash rapidly two or three times and then pause. This is now telling you the computer is ready to produce the stored trouble codes. Turn the grounded lead to the "off" position (remove the ground from the circuit) this will enable the computer to produce the first digit of the trouble code, pause and then produce the second digit of the trouble code. For example, if the check engine light flashes twice and then pause and blink two more times the code number would be 23. Some codes are single digit in the case the check engine light will only blink one set. 

To clear trouble codes after the repairs have been made remove the negative battery cable for two minutes and reconnect or turn the jumper lead to the "on" position, after three short blinks of the check engine light turn the switch off the light will blink 12444. This means there are no more codes stored in the computer’s memory and the system is reset.
