- Keyless Entry Transmitter 2 Low Battery
DTC B3111 00
- Keyless Entry Transmitter 3 Low Battery
DTC B3112 00
- Keyless Entry Transmitter 4 Low Battery
Circuit/System Description
With each press of a keyless entry transmitter button, a message containing the current battery state of the transmitter is sent to the remote control
door lock receiver (RCDLR) along with the commanded keyless entry function.
Conditions for Running the DTC
A keyless transmitter button is pressed.
Conditions for Setting the DTC
The DTC sets after 3 consecutive low battery signals from the same programmed transmitter.
Action Taken When the DTC Sets
The keyless entry system is inoperative.
Conditions for Clearing the DTC
The DTC is cleared when a normal transmitter voltage signal is received from the programmed transmitter that set the DTC.
Diagnostic Aids
The keyless entry transmitter used in the 2-Way Advanced Remote Start System is unique to the system. When servicing or replacing a transmitter,
ensure that the correct transmitter is used. The correct transmitter part number can be found in the Accessory section of the parts catalog.
Attempting to replace a 2-Way Advanced Remote Start transmitter with a regular service part may result in a failure to program the transmitter.

DTC B153B 02
- Liftgate Open Switch Signal Circuit Short to Ground
DTC B153B 05
- Liftgate Open Switch Signal Circuit Open
Diagnostic Fault Information
Circuit/System Description
The full open switch is part of the gear motor assembly and will close and become active when the liftgate reaches the full open position. The full
open switch signal circuit is supplied battery voltage through a resistor and monitored within the liftgate control module. The liftgate control
module (LGM) provides a low reference circuit and when the switch contacts close, the signal circuit goes low and the LGM determines the switch
to be active.
Conditions for Running the DTC
* The system voltage is 9-16 volts.
* Power open or close operation is attempted.
Conditions for Setting the DTC

then DTC P0AFB will set.
Conditions for Running the DTC
* The engine is running or is in autostop mode.
* The 12 V system voltage is between 9.5-18 V.
Conditions for Setting the DTC
The ACCM detects that the hybrid battery voltage is greater than 415 V for 3 seconds.
Action Taken When the DTC Sets
The air conditioning is disabled.
Conditions for Clearing the DTC
* The DTC will pass when the ACCM detects a hybrid battery voltage less than 405 V for 3 seconds.
* A history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
Diagnostic Aids

Circuit/System Description
The drive motor generator battery has four hybrid battery temperature sensors. The hybrid battery temperature sensors are located on the top of the
hybrid batteries. The temperature sensor is a variable resistor that measures the temperature of the hybrid batteries. The control module supplies 5 V
to the signal circuit and a ground for the low reference circuit. The hybrid battery temperature sensor resistance changes with battery temperature.
The lower the temperature, the higher the resistance of the sensor. The higher the temperature, the lower the resistance of the sensor. The drive
motor generator battery control module (BECM) uses the battery temperature sensors to determine the hybrid battery temperature to control the
battery cooling fan operation.

DTC P071A
- Transmission Tow Mode Switch Circuit
Circuit/System Description
Tow/haul mode enables the operator to achieve enhanced shift performance when towing or hauling a load. When tow/haul mode is selected, the
tow/haul switch input signal to the body control module (BCM) is momentarily toggled to zero volts. This signals the transmission control module
(TCM) to extend the length of time between upshifts and increase transmission line pressure. Cycling the tow/haul switch again disables tow/haul
mode and returns the transmission to a normal shift pattern.
Conditions for Running the DTC
* No Transmission Mode Switch Signal DTC P1762.
* The engine speed is greater than 500 RPM for 5 seconds.
* The system voltage is 8-18 volts.
Conditions for Setting the DTC
The Tow Mode switch remains closed, low voltage, for 600 seconds.
Action Taken When the DTC Sets
DTC P071A is a Type C DTC.
Conditions for Clearing the DTC
DTC P071A is a Type C DTC.
Diagnostic Aids
If the electrical circuit tests are OK and the shift pattern is not occurring, there may be a mechanical/hydraulic condition that prevents operation.

Circuit/System Description
The heated oxygen sensors (HO2S) are used for fuel control and catalyst monitoring. Each HO2S compares the oxygen content of the surrounding
air with the oxygen content of the exhaust stream. When the engine is started, the control module operates in an Open Loop mode, ignoring the
HO2S signal voltage while calculating the air-to-fuel ratio. While the engine runs, the HO2S heats up and begins to generate a voltage within a
range of 0-1,275 mV. Once sufficient HO2S voltage fluctuation is observed by the control module, Closed Loop is entered. The control module

DTC P1A8B 00
- 42 Volt Inverter Temperature High
DTC P1A8B 11
- 42 Volt Inverter Temperature High
DTC P1A8C
- 42 Volt Inverter Overtemperature
Circuit/System Description
The Accessory Power Module (APM) controls the energy flowing between the high voltage, 300-volt, direct current (DC) and intermediate voltage,
42-volt, DC to support the Electric Power Steering (EPS). The APM receives a 42-volt enable command from the Hybrid Powertrain Control
Module (HPCM) over the high speed hybrid GMLAN communication circuit. APM functions will run only when the APM Enable is active on the
high speed hybrid GMLAN communication circuit.
Heat is generated in the 42-volt APM circuit solely through the demand for use of the EPS. The Engine Control Module (ECM) measures the
temperature of the Power Electronics Cooling Loop and commands the flow of 2 electrical coolant pumps. The APM transfers heat in the 42-volt
circuit to the APM Heat Plate which is then dissipated at the Power Electronics Front End Heat Exchanger.
Based on the severity of an overheat condition in the 42-volt circuit, the APM will make decisions ranging from notification of an over temperature
condition to the EPS to completely shutting down the 42-volt power conversion.
