Obd-1 Codes for the 93-95 Ford Probe, Mx6 & 626
The OBD-1 computer system was used in the 93-95 Ford Probe, Mx6 & 626
- To check for OBD-1 codes, use a paperclip and insert it into the 10 and ground pins in the diagnostics box under the hood by the battery.
- Make sure the engine is turned off .
- Once the paperclip is inserted, turn the key to the “on” position, but do NOT start it.
- Start to read the codes, quick flashes are single digits, and slightly longer flashes represent 10’s or 100’s (Example: 2 long flashes and 3 short flashes would be code 23)
