Brake Lamp Switch
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before proceeding with this diagnostic test, verify the adjustment of the stoplight switch to rule out misadjustment. See BRAKE LAMP SWITCH
under ADJUSTMENTS. If the electrical circuit has been tested and the brake lamp switch is suspected of being faulty, it can be tested using the following methods.
- Remove the switch from the vehicle. See BRAKE LAMP SWITCH under REMOVAL & INSTALLATION.
- With the switch in the released position (plunger extended), use an ohmmeter to test each of the 3 internal switches. See Fig 1 . Switch should achieve the results indicated in the illustration.
- Gently push the plunger on the stoplight switch in until it stops.
- With the switch in the depressed position (plunger pushed in), use an ohmmeter to test each of the 3 internal switches. See Fig 2 . Switch should achieve the results indicated in the illustration.
- If switch did not achieve the results as shown in both illustrations, the switch is faulty and must be replaced.
