Test H: Flash Code 3 - DEACTIVATOR Switch Circuit Failure

  1. Disconnect speed control actuator 10-pin harness connector C122. Measure voltage between speed control actuator harness connector C122 terminals No. 9 (Red/Light Green wire) and No. 10 (Black wire). See Figure . If 10 volts or less exist, go to next step. If more than 10 volts exist, replace speed control actuator. See SPEED CONTROL ACTUATOR  under REMOVAL & INSTALLATION.
  2. Disconnect deactivator switch 2-pin harness connector C277. Measure resistance between deactivator switch terminals (component side). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace deactivator switch. See SPEED CONTROL DEACTIVATOR SWITCH  under REMOVAL & INSTALLATION.
  3. Measure voltage between ground and deactivator switch harness connector C277 Light Green/Red wire terminal. If more than 10 volts exist, repair open in Red/Light Green wire. If 10 volts or less exist, repair open in Light Green/Red wire.
