July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Code 10, Stoplight Switch On Constantly

  1. Turn ignition off. Disconnect EBCM harness connector from EBCM. Turn ignition on. Measure voltage between EBCM harness connector terminal No. 8 (Green/White wire) and ground.
  2. If reading is less than 10 volts, replace EBCM. See RWAL ELECTRONIC CONTROL MODULE  under REMOVAL & INSTALLATION. If reading is 10-15 volts, replace or adjust stoplight switch or repair short to voltage in Green/White wire.
