2004 Volvo V70 L5-2.5L Turbo VIN 59 B5254T2SECTION Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code information
Condition
The automatic transmission checks that lock-up is not engaged or slips by comparing the rpm signal from the transmission speed (rpm) sensor to the engine speed. The signals must then show the same calculated speed (rpm). If the control module detects that the engine speed (RPM) signals do not correspond with the programmed values, it means that lock-up is slipping or does not engage in the locked position. The diagnostic trouble code (DTC) is stored.
