BRAKELIGHT Switch

NOTE: Brakelight switch consists of 2 internal switches: Cruise brake switch (dedicated to cruise control system) and brakelight switch (part of brakelight system).
  1. Disconnect brakelight switch 4-pin connector. Using ohmmeter, check continuity between all 4 terminals. With brake pedal released, continuity should exist between brakelight switch terminals No. 2 and 3. See Fig 1.
  2. With brake pedal released, continuity should not exist between brakelight switch terminals No. 1 and 4. If continuity is not as specified, replace brakelight switch.
