1993 to 1995 850's have the diagnostic connector beside the windshield washer fill. Click and read the Bay 13 link on how to read the 1993 to 1995 Diagnostic Connectors Check Engine codes and how to clear them.

THE USE OF THE FOLLOWING INFORMATION IS ENTIRELY AT THE USERS RISK

To retrieve the flash codes the following procedure can be adopted:
Connect an LED, with the correct polarity, in series with a 1k8 ohm resistor, between pin 16 (+) and pin X, where X is the pin corresponding with the module to be read. Connect a push to make switch between pin X and pins 4 or 5 (-).
The circuit can then be used in the same way as the pre '96 diagnostic sockets, situated in the engine compartment.
For:
Motronic 4.3 or Fenix 5.2, X = 3.
ECC , X = 6, Timer Type 4, X = 9.
Cruise Control, X = 13; 900 & S/V 90 ABS, X = 12 .

What the codes mean:
