DTC Table, ABS And TRACS
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.
Faults can be of two kinds, intermittent or permanent. Intermittent faults are temporary, sometimes recurrent faults. Permanent faults are as the name implies.
NOTE:
Switch ignition off before connecting or disconnecting connector or test box. Otherwise the control module may be damaged.
