Read-Outs With Volvo Diagnostics

Read-outs with Volvo Diagnostics




Data on any faults and other information can be read out with the Volvo ST connected to the DLC on the console in front of the gear lever. The Volvo ST communicates with the control module via a standardized communications program.

You can use the Volvo ST to:
- Read out and erase posted DTCs, the counter and frozen values.
- Read out control module input and output signal values and status continuously.
- Read the control module ID.




The DLC is common to both Volvo Diagnostics and the less sophisticated diagnostic system OBD II, On Board Diagnostics II (OBD II some markets only, USA/CDN).

Connecting the Volvo ST:
- Ignition off.
- Install memory module
- Connect Volvo ST by leads to DLC in console in front of gear lever.
- Ignition on
- Switch power on to Volvo ST.
- Select language, model, function group.
- Select system.
- Select operation (read, erase, DTCs, activate components etc.).





To activate Volvo Diagnostics:
- Ignition must be on.
- Battery voltage must be normal.
- Speed of all wheels must be less than 10 km/h (6 mph).
- The control module must not have activated ABS, EBD or TRACS.
Once the control module has activated Volvo Diagnostics, the ABS warning light will start flashing at a frequency of 2 Hz.
When activation of Volvo Diagnostics ends, the warning light stops flashing and the control module returns to its normal position for ABS, EBD and TRACS.
