Accessing Trouble Codes

89-93 models (and later non-turbo/non-OBDII models)

Fuel Codes
Locate the diagnostic unit behind left strut tower and remove its cover.(see image) Connect selector cable to socket #2,which tests the fuel codes. Turn the ignition switch to the ON position(engine not running). Enter the diagnostic mode by pressing the push button on the diagnostic unit for at least 1 second, but not more than 3 seconds. The red LED light will start to flash,count the number of flashes in 3 flash intervals. The flashes will be seperated by 3 second intervals.Make note of all codes. If no codes are stored,the LED will flash 1-1-1,which means the fuel system is operating correctly.

Ignition Codes
To access the ignition codes,follow the above procedure,but with the selector cable connected to the #6 socket on the diagnostic unit. NOTE:Turbocharged models may have seperate codes for the turbo system and are accessse by hooking the selector cable to the #5 socket.

94 and later models with OBDII

The 850 turbo and 960 models are OBD II system which are only accessible with a scanner.

Clearing Trouble Codes

Once all faults have been corrected,turn the ignition switch to the ON position(engine not running).Recheck the codes,then depress the button for 5 seconds and release.After 3 seconds, the LED should light up.While the LED is lit,depress the button again for 5 seconds,when the button is released,the LED should go out.

Hello Laurentlu. Code 267 is cylinder 3 injector fault. Im guessing it is running roughly for you? A bad fuel injector will make your car run as if it has the flu. This code is for an american made volvo, but is probably the same for your petrol engine.
