DTC B1024 11

- Circuit Board Temperature Sensor Above Maximum Threshold

Circuit/System Description

The audio amplifier monitors the internal circuitry for excessive temperature. When the amplifier senses an internal circuitry temperature greater

than 95掳C (203掳F), the amplifier will set DTC B1024 11 and shut down until the internal circuitry cools below 90掳C (194掳F).

Conditions for Running the DTC

* Radio ON.

* Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

The audio amplifier detects an over-heat condition greater than 95掳C (203掳F) of the internal amplifier circuitry.

Action Taken When the DTC Sets

The audio amplifier will shut down and all speakers will be inoperative.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.

* A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred.

Diagnostic Aids

Extended use or extremely high volume especially in warm weather conditions may cause this DTC to set. Under these conditions it may be normal

for this DTC to set to prevent permanent damage to the audio amplifier circuitry.

DTC Descriptor

DTC P0BFD

- Drive Motor 1 Phase U-V-W Correlation

DTC P0BFE

- Drive Motor 2 Phase U-V-W Correlation

Circuit/System Description

The drive motor generator power inverter control module (PIM) contains two motor control modules (MCMs) and the hybrid powertrain control

module (HPCM). Each MCM operates its respective drive motor generator based upon HPCM commands. Each MCM controls the speed, direction

and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate

bipolar transistors (IGBTs). Each drive motor generator operates utilizing 3-phase alternating current (ac) electricity. Each IGBT operates a single

phase of the drive motor generator. Each phase is individually identified as U, V and W. Each MCM monitors the current of each phase in order to

detect PIM overcurrent conditions.

Because all the motor generator phase circuits are electrically joined together, they should each flow about the same amount of current. The MCM

performs a mathematical calculation to verify that the phase current sensors are accurate. If the U-V-W phase current sensors indicate about the

same amount of phase current, the sum of the calculation should be near zero. If the U-V-W phase currents are not similar, this DTC will set.

Conditions for Running the DTC

* The ignition is ON.

* The High Voltage contactor relays are closed.

Conditions for Setting the DTC

The sum of the 3 phase current sensors is greater than 75 A.

Action Taken When the DTC Sets

* DTCs P0BFD and P0BFE are Type A DTCs.

* The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P0BFD and P0BFE are Type A DTCs.

DTC P06B4

- Sensor Positive Voltage Circuit 2 Low Voltage

DTC P06B5

Circuit/System Description

The drive motor generator power inverter module (PIM) contains two motor control modules (MCM) and a hybrid powertrain control module

(HPCM). The MCMs share an internal 15 volt reference power supply in order to operate the drive motor sensors processors. This fault is handled

inside the PIM and no external circuits are involved.

Conditions for Running the DTC

* The control module runs the program to detect an internal fault when the key is ON.

* Ignition voltage is 8-18V.

Conditions for Setting the DTC

P06B1 or P06B4

The reference voltage is less than 12 V for 1 second.

P06B2 or P06B5

The reference voltage is greater than 18 V for 1 second.

Action Taken When the DTC Sets

* DTCs P06B1, P06B2, P06B4 and P06B5 are Type B DTCs.

* The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P06B1, P06B2, P06B4 and P06B5 are Type B DTCs.

DTC Descriptor

DTC P0BFD

- Drive Motor 1 Phase U-V-W Correlation

DTC P0BFE

- Drive Motor 2 Phase U-V-W Correlation

Circuit/System Description

The drive motor generator power inverter control module (PIM) contains two motor control modules (MCMs) and the hybrid powertrain control

module (HPCM). Each MCM operates its respective drive motor generator based upon HPCM commands. Each MCM controls the speed, direction

and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate

bipolar transistors (IGBTs). Each drive motor generator operates utilizing 3-phase alternating current (ac) electricity. Each IGBT operates a single

phase of the drive motor generator. Each phase is individually identified as U, V and W. Each MCM monitors the current of each phase in order to

detect PIM overcurrent conditions.

Because all the motor generator phase circuits are electrically joined together, they should each flow about the same amount of current. The MCM

performs a mathematical calculation to verify that the phase current sensors are accurate. If the U-V-W phase current sensors indicate about the

same amount of phase current, the sum of the calculation should be near zero. If the U-V-W phase currents are not similar, this DTC will set.

Conditions for Running the DTC

* The ignition is ON.

* The High Voltage contactor relays are closed.

Conditions for Setting the DTC

The sum of the 3 phase current sensors is greater than 75 A.

Action Taken When the DTC Sets

* DTCs P0BFD and P0BFE are Type A DTCs.

* The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P0BFD and P0BFE are Type A DTCs.
