Overview

The center of the electric motor control system is a microprocessor called the PCM . The PCM receives inputs from sensors and other electronic components. Based on information received and programmed into its memory, the PCM generates output signals to control various relays, solenoids, and actuators. This vehicle uses two PCM connectors.

The PCM stores information in keep alive RAM (a memory integrated circuit chip) about vehicle operating conditions, and then uses this information to compensate for component variability. Keep Alive Memory (KAM) remains powered when the ignition is off so this information is not lost.

The Vehicle Battery Power (VBPWR) is a PCM -supplied power source that supplies regulated voltage (5 to 12 volts) to vehicle sensors that run off 12 volts but cannot withstand VPWR voltage variations. It is regulated to VPWR minus 1.5 volts and is voltage limited to protect the sensors. VPWR is the primary source of PCM power. VPWR is switched through the PCM power relay and is controlled by the PCM . The VREF is a positive voltage (about 5 volts) that is output by the PCM. This is a consistent voltage that is used by the three-wire sensors. The Signal Return (SIG RTN) is a dedicated ground circuit used by the sensors and some of the other PCM inputs.

Symptom Chart

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices.

REFER to: DIAGNOSTIC METHODS .

In most circumstances, the PCM sets Diagnostic Trouble Codes (DTCs) to help guide with diagnostics. Refer to the DTC Chart in DTC Chart Powertrain Control Module (PCM) before using the symptom chart. The Condition column lists the vehicle condition. The Source column list a detailed vehicle condition. The Action to column lists the action be performed to determine the cause of the condition. Each action lists the components that can cause the system and the individual components in that system. The components are listed in order of disassembly. Use the list of components and the required action to focus on disassembly inspections for the root cause of the concern.

Refer to SYSTEM WIRING DIAGRAMS for schematic and connector information.

Normal Operation and Fault Conditions

The Ambient Air Temperature (AAT) sensor is a negative temperature coefficient thermistor which senses the outside air temperature. The PCM sends a 5-volt signal to the Ambient Air Temperature (AAT) sensor. Based on the voltage level, the PCM determines the outside temperature. The PCM sends this information to the BECM to the climate control system. When the PCM senses a signal voltage high or voltage signal low, the PCM sets a DTC .

The motor electronics coolant temperature sensor is a temperature-sensitive device called a thermistor. The resistance value of the motor electronics coolant temperature sensor varies with temperature change. The PCM provides a signal voltage to the motor electronics coolant temperature sensor. The PCM monitors the voltage across the motor electronics coolant temperature sensor to determine the temperature of the electric motor coolant. The PCM sets a DTC if voltage on these inputs are above or below a calibrated threshold.

WARNINGTo prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

The PCM monitors the DC to DC Converter Control Module (DC/DC), PTC heater, the A/C compressor module and the TCM high voltage circuits. The high voltage interlock system verifies these connectors are properly connected. The PCM sends a 5-volt reference signal to each connector, in series and monitors the voltage return. The PCM high voltage interlock sense input checks for continuity of the high-voltage system interlock circuit. The interlock circuit must have continuity before high-voltage is supplied to the vehicle. The interlock circuit voltage travels through each of the high-voltage components and high-voltage cables and back to the PCM. The PCM sets a DTC if voltage on these inputs are above or below a calibrated threshold.

There are 2 APP signals in the sensor. Both signals, APP 1 and APP 2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 APP signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and two signal circuits (a total of 6 circuits and terminals) between the PCM and the APP sensor assembly. The APP signal is converted to pedal travel degrees (rotary angle) by the PCM . The software then converts these degrees to counts, which is the input to the torque based strategy. The PCM sets a DTC if voltage on these inputs are above or below a calibrated threshold.

The battery pack coolant temperature sensor is a temperature-sensitive device called a thermistor. The resistance value of the battery pack coolant temperature sensor varies with temperature change. The PCM provides a signal voltage to the battery pack coolant temperature sensor. The PCM monitors the voltage across the battery pack coolant temperature sensor to determine the temperature of the electric motor coolant. The PCM sets a DTC if voltage on these inputs are above or below a calibrated threshold.
