Brake Light Switch: Testing and Inspection
NOTE: Before proceeding with this diagnostic test, verify the adjustment of the brake lamp switch to rule out misadjustment. If misadjusted, replace the
switch. It cannot be readjusted.
If the electrical circuit has been tested and the brake lamp switch is suspected of being faulty, it can be tested using the following method.
1. Remove the switch from the vehicle.
Fig.1 Switch Test - Released Position
2. With the switch in the released position (plunger extended), use an ohmmeter to test each of the three internal switches as shown. You should
achieve the results as listed in the figure.
3. Gently push the plunger on the brake lamp switch in until it stops.
Fig.2 Switch Test - Depressed Position
4. With the switch in this depressed position (plunger pushed in), use an ohmmeter to test each of the three internal switches as shown. You should
achieve the results as listed in the figure.
If you do not achieve the results as listed in both figures, the switch is faulty and must be replaced.
If the switch is found to be operating properly, do not reinstall it, replace the switch.
CAUTION: The switch can only be adjusted once. That Is during initial Installation of the switch. If the switch is not adjusted properly or has been
removed for some service, a new switch must be Installed and adjusted.
