Code 22: BRAKELIGHT Switch
WARNING: This page is about a different car, the 1994 Mitsubishi Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect brakelight switch connector. On models with cruise control, connect ohmmeter across switch terminals "A" and "B". See Fig 1 . On models without cruise control, connect ohmmeter across switch terminals.
- With brake pedal depressed (plunger extended), continuity should exist between switch terminals. With brake pedal released (plunger retracted), continuity should not exist.
- If Code 22 is stored and brakelight switch tests okay, check continuity between brakelight switch (Green wire) and terminal No. 18 of ECU. Inspect and repair circuit as needed.
