Frozen Values

Frozen values

When the control module detects a fault in the system and a diagnostic trouble code (DTC) is set, six different parameters in the control module memory are frozen.
Exceptions to this procedure are the diagnostic trouble codes (DTCs) PSL/PSR-323, PSL/PSR-322, PSL/PSR-321, PSL/PSR-421, PSL/PSR-424. For these DTCs no parameters are frozen.
The parameters frozen for a diagnostic trouble code (DTC) are an individual selection of parameters in Volvo Scan Tool (ST) Scrolling values Volvo Scan Tool (ST) Scrolling Values.
