Volvo OBD1 Trouble Codes
The following trouble codes are specific to Volvo.
Volvo Trouble Codes Access
Without OBD Scan Tool
To start, the Ignition key must be at position II, engine not running. Open the hood. Locate the two diagnostic sockets just inboard of the washer fill cap. The ‘A’ connector has a jumper that is stored in the lid of the ‘A’ diagnostic connector. The jumper is used for both diagnostic connectors.
Listed below is the information retrievable from the various connections.
- 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
Volvo Trouble Codes Clearance
All trouble codes must be cleared from the ECU’s memory after repairing the faults. Otherwise, code(s) would remain in the ECU’s memory indefinitely and would appear along with a new code in the event of a future problem. To clear the trouble codes, proceed as follows:
- Push and hold the button for 6-7 seconds
- Release, and as soon as the LED comes on push and hold the button for another 6-7 seconds.
- Now push the button for 1 second and read the codes again, you should get 1-1-1 (no faults).
