Pinpoint Test E: Flash Code 3 - Speed Control DEACTIVATOR Switch Circuit Failure

WARNING: This page is about a different car, the 2009 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connectors.
  1. E1 CHECK THE SPEED CONTROL DEACTIVATOR SWITCH SIGNAL 
    NOTE: The following step uses a test light to simulate normal circuit loads. Use only the test lamp or equivalent recommended in the Special Tool(s) . To avoid connector terminal damage, use the Rotunda Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test lamp probe directly on any connector.
    • Ignition OFF.
    • Disconnect: Speed Control Actuator C122.
    • Ignition ON.
    • While applying and releasing the brake pedal, measure the voltage between the speed control actuator C122-9, circuit CES09 (VT/OG), harness side the speed control actuator C122-10, circuit GD123 (BK/GY), harness side.

    • Is the voltage greater than 10 volts with the brake pedal released and 0 volts when the brake pedal is applied? 
    • Yes  : INSTALL a new speed control actuator. REFER to SPEED CONTROL ACTUATOR . REPEAT the self-test.
    • No  : GO to E2  .
  2. E2 CHECK THE SPEED CONTROL DEACTIVATOR SWITCH VOLTAGE SUPPLY 
    NOTE: The following step uses a test light to simulate normal circuit loads. Use only the test lamp or equivalent recommended in the Special Tool(s) . To avoid connector terminal damage, use the Rotunda Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test lamp probe directly on any connector.
    • Ignition OFF.
    • Disconnect: Speed Control Deactivator Switch C277.
    • Ignition ON.
    • Measure the voltage between the speed control deactivator switch C277-1, circuit CBP26 (BU/WH), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to E3  .
    • No  : VERIFY the SJB  fuse 26 (2A) is OK. If OK, REPAIR the circuit. REPEAT the self-test. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short.
  3. E3 CHECK THE SPEED CONTROL DEACTIVATOR SWITCH SIGNAL CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Measure the resistance between the speed control actuator C122-9, circuit CES09 (VT/OG), harness side and the speed control deactivator switch C277-2, circuit CES09 (VT/OG), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes  : INSTALL a new speed control deactivator switch. REFER to SPEED CONTROL DEACTIVATOR SWITCH . REPEAT the self-test.
    • No  : REPAIR the circuit. REPEAT the self-test.
