Stoplight Switch
Remove stoplight switch connector. Depress brake pedal (switch pin free) and ensure continuity exists between stoplight switch terminals No. 1 (Green/White wire) and No. 2 (Green/Red wire). Release brake pedal (switch pin pushed in) and ensure continuity exists between stoplight switch terminals No. 3 (Yellow/Red wire) and No. 4 (Yellow/Green wire). If continuity is not present as specified, replace stoplight switch.
