Read and Understand Volvo Diagnostic Codes On 1992-1995 Volvos

This video will show you where the diagnostic port is located on pre 1996 Volvos’ and how to retrieving codes on 1992-1995 Volvos, pre OBD 2. Also this video will show you how to clear the check engine light on 1992 – 1995 Volvos. This is also know as reading ‘blink codes’ on a Volvo. Listed below is the information retrievable from different slots, when recording this video I was in the A2 slot. A1 Transmission B1 Climate Control A2 Fuel System B2 Cruise Control A3 ABS B5 SRS A5 TCU (Transmission Control) B6 Power Seat A6 Ignition System A7 Combined Instrument
