Car communication

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

The following can be read off using car communication:

Read diagnostic trouble codes (DTCs)

ME 7.0 engine management system contains approximately 135 diagnostic trouble codes (DTC). Each diagnostic trouble code (DTC) can give information on whether the fault depends on an open-circuit, short-circuit to supply voltage or short-circuit to ground. This gives a combined total of 405 different diagnostic trouble codes (DTCs).

The following output signals/components can be activated:

Activation

Injectors (sequentially)
Power stages/ignition coils (sequentially)
air conditioning (A/C) relay (compressor clutch)
Output signal engine coolant temperature sensor
Indicator lamp CRUISE
Econometer signal to the Driver information module (DIM)
Engine cooling fan (FC) (3 speeds)
Engine speed (RPM) to DIM
Electronic Throttle System warning lamp
EVAP canister shut-off valve
Turbocharger (TC) control valve
Canister purge (CP) valve
Fuel pump (FP) relay
Malfunction Indicator Lamp (MIL)
Heating front heated oxygen sensor (HO2S)
Heating rear heated oxygen sensor (HO2S)
Continuous Variable Valve Timing (CVVT) camshaft control valve
Interlock function (starter motor relay),USA/CDN only

Reading off plotter

Here curves and values for approximately 90 parameters can be read off. As before a maximum of 3 can be read at the same time.

Activating diagnostic functions

This is a new function for activating the different test phases in the following on-board diagnostic (OBD) systems:

Return Fuel Lacking System (RFLS)
Pulsed secondary air injection system (PAIR)
