Easy step by step guide on how to retrieve and define Saab OBD1 trouble codes.
Difficulty Scale: 2 of 10
Begin by parking the vehicle on level ground, engine off, with the parking brake
Step 1 - Saab has used the check engine light on
the instrument cluster to alert the driver that 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.
Step 2 - 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.
Step 3 - 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. The computer is ready to produce the stored trouble codes.
Step 4 - 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 pauses
and then blinks three more times, the code number would be 23. Some codes are a single
digit in the case the check engine light will only blink one set.
Step 5 - 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.
