Brake Lamp Switch

OVERVIEW






The brake lamp switch can be tested with an ohmmeter. The ohmmeter is used to check continuity between the pin terminals.

SWITCH CIRCUIT IDENTIFICATION
^ Terminals 1 and 2: brake lamp circuit
^ Terminals 3 and 4: RWAL/ABS module and Powertrain Control Module (PCM) circuit
^ Terminals 5 and 6: speed control circuit

SWITCH CONTINUITY TEST

NOTE: Disconnect switch harness before testing switch continuity.

With switch plunger extended, attach test leads to pins 1 and 2. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 3 and 4. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 5 and 6. Replace switch if meter indicates no continuity.
