The brake lamp switch can be tested with an ohm-meter 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.
