Service Mode 03. DC Quick (Table dC Routines)
Once in the Service Mode, diagnostic routines can be selected from the DC Quick menu.
Procedure
- Enter the PWS Diagnostic mode.
- Using the DC Quick pull-down menu (upper-right side of Diagnostics Service Entry Screen), select the desired dC routine. Table 1 is a complete list of dC routines that are available from the DC Quick pull-down menu.
