Brake light switch, removing and installing/adjusting: Notes
Two different styles of brake light switch were used in production. For servicing purposes they will be referred to here as "old style" and "new style".
It is important to identify which style of switch is installed prior to servicing as each requires specific removal and installation/replacement procedures.
- On Diesel models and gasoline models with cruise control, Brake Switch -F- and Brake Pedal Switch (cruise control/DFI) -F47- are integrated. The following procedures apply to all models regardless of switch.
- Only "old style" switches can be removed and reinstalled/adjusted.
- "New style" switches must NOT be reused after removal. Always replace.
