Reading off input and output signals
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.
Using this function the values and status of the control module input and output signals can be continuously read off.
The following parameters can be read off:
- Vehicle speed, value
- Fuel level signal to needle, value
- Fuel level signal from sensor, value
- Engine coolant temperature (ECT), value
- Engine speed (RPM), value
- Generator (GEN) charge voltage D+, status
- Oil pressure in engine, status
- Fuel level warning lamp, status
- Service reminder indicator (SRI), status
- Outside temperature warning lamp, status
- 12 pulse vehicle speed signal, status
- 48 pulse vehicle speed signal, status
- Vehicle speed signal to speedometer, status
- Outside temperature, signal from sensor, value
- Outside temperature, signal from control module, value
- Fuel flow signal, value
NOTE:
When the lamp check function is carried out, the parameters low fuel level and service reminder indicator (SRI) are not updated.
To obtain the relevant value the 12-pulse and the 48-pulse vehicle speed signal should be read off when the front wheels rotate.
