Diagnostic Fault Information
Circuit/System Description
The hybrid battery current sensor is mounted inside the drive motor generator battery assembly. The positive high voltage cable that goes to the
positive contactor relay passes through the current sensor. The current sensor detects the amperage that flows in and out of the hybrid batteries. The
drive motor generator battery control module supplies and monitors a 5 V reference signal to the current sensor. The current sensor returns a signal
between 0 and 5 V to the drive motor generator battery control module. The current sensor signal is in proportion to the amperage going in and out
of the drive motor generator battery. A signal voltage of the current sensor greater than 2.5 V indicates that the drive motor generator battery is
being discharged and a signal voltage less than 2.5 V indicates charging. The hybrid battery current sensor has 3 measurement ranges in order to
maintain accuracy. The ranges are low, medium and high. The measurement ranges of the current sensor have some overlap with each other. The
low range measures from -22 to +22 A. The medium range measures from -52 to +52 A. The high range measures from -250 to +250 A.

Diagnostic Fault Information
Circuit/System Description
The system contains twenty battery modules. Each module contains two 7.2 V cells for a total nominal system voltage of 288 V. Each battery
module is rated at 14.4 V direct current (DC) and all the modules are connected together in series. The drive motor generator battery is also referred
to as the hybrid battery.
The drive motor generator battery control module has several methods of monitoring the total voltage values of the hybrid batteries. The drive
motor generator battery control module monitors the calculated battery voltage and the terminal voltage. The calculated voltage represents the sum
of the voltages from the 20 individual battery measurements, and the terminal voltage represents the total DC bus voltage as measured on the output
side of the high voltage contactor. The drive motor generator battery control module compares these two voltage readings and looks for a
difference. The drive motor generator battery control module also monitors the terminal voltage for both over voltage and under voltage conditions.
Conditions for Running the DTC
* The ignition is ON.
* The 12 V battery voltage is 9-18 V.
* The high voltage contactors are closed.
Conditions for Setting the DTC
P0ABB
The drive motor generator battery control module detects a 50 V difference between the hybrid battery pack calculated voltage and the hybrid

DTC P1A07
- Battery Energy Control Module 5-Volt Reference Circuit
Diagnostic Fault Information
Circuit/System Description
The hybrid battery current sensor is mounted inside the drive motor generator battery assembly. The positive high voltage cable that goes to the
positive contactor relay passes through the current sensor. The current sensor detects the amperage that flows in and out of the hybrid batteries. The
drive motor generator battery control module supplies and monitors a 5 V reference signal to the current sensor. The current sensor returns a signal
between 0 and 5 V to the drive motor generator battery control module. The current sensor signal is in proportion to the amperage going in and out
of the drive motor generator battery. A signal voltage of the current sensor greater than 2.5 V indicates that the drive motor generator battery is
being discharged and a signal voltage less than 2.5 V indicates charging. The hybrid battery current sensor has 3 measurement ranges in order to
maintain accuracy. The ranges are low, medium and high. The measurement ranges of the current sensor have some overlap with each other. The
low range measures from -22 to +22 A. The medium range measures from -52 to +52 A. The high range measures from -250 to +250 A.
Conditions for Running the DTC
* The ignition is ON.
* The 12 V battery is 9-18 V.
Conditions for Setting the DTC
P0AC0
One of the following conditions exists:
* The drive motor generator battery control module detects greater than 5 A on the current sensor after a successful high voltage system power
down and after the contactors have opened.
* The drive motor generator battery control module detects an increase in total pack voltage greater than 10 V and the current sensor measures
less than a 0.5 A increase.
