Reading off diagnostic trouble codes (DTCs)

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.

HINT: If the starter motor does not run, the fault may be due to an internal fault in the gear-shift position sensor. In certain cases the transmission control module (TCM) has been unable to store diagnostic trouble codes (DTCs) because not all the conditions have been met.
