Car Communication

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The following can be read off during 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).

Activation

The following output signals/components can be activated:

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 Can and Driver information Module
Engine cooling fan (FC) (High or low speed)
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)
