DTC P0521
- Engine Oil Pressure (EOP) Sensor Performance
DTC P0522
- Engine Oil Pressure (EOP) Sensor Circuit Low Voltage.
DTC P0523
- Engine Oil Pressure (EOP) Sensor Circuit High Voltage
Diagnostic Fault Information
Circuit/System Description
The engine oil pressure (EOP) sensor changes voltage based on the engine oil pressure. The EOP sensor is a 3-wire sensor comprising of the signal
circuit, the low reference circuit and the 5-volt reference circuit. The engine control module (ECM) supplies 5 volts to the EOP sensor via the 5-volt
reference circuit and provides ground via the EOP low reference circuit. The ECM monitors the signal circuit of the EOP sensor to determine the
EOP sensor voltage is within the normal operating range of approximately 1-4 volts. When the engine oil pressure is high, the EOP sensor voltage
is high and the ECM senses a high signal voltage. When the engine oil pressure is low, the EOP sensor voltage is low and the ECM senses a low
signal voltage. The ECM sends the EOP information to the instrument panel cluster (IPC) via GMLAN serial data message.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
P0521

DTC P0455
- Evaporative Emission (EVAP) System Large Leak Detected
Circuit/System Description
The ECM tests the Evaporative Emission (EVAP) System for a large leak or restrictions to the purge path in the EVAP system. When the enabling
criteria has been met the ECM commands the EVAP canister vent solenoid valve ON and the EVAP canister purge solenoid valve ON, allowing
vacuum into the EVAP system. The ECM monitors the fuel tank pressure (FTP) sensor voltage to verify that the system is able to reach a
predetermined level of vacuum within a set amount of time.
Conditions for Running the DTC

Conditions for Clearing the MIL/DTC
DTC P0455 is a Type B DTC.
Diagnostic Aids
* Inspect for a loose, missing, damaged, or incorrect fuel fill cap.
* Inspect for a damaged fuel filler neck seal surface.
* A blockage or restriction in the EVAP purge solenoid valve, purge pipe, EVAP canister, or vapor pipe, can cause this DTC to set.
* The EVAP system can be filled with smoke more quickly and completely by opening the system opposite the end where the smoke is
injected. For example, when injecting smoke at the service port remove the fuel fill cap, or temporarily leave the vent open, until smoke is
observed, then close the system and continue testing. If using a fuel cap adapter at the filler neck, use the J 41413-VLV at the service port to
allow the system to fill faster.
* To help locate intermittent leaks using the J 41413-200, move all EVAP components while observing smoke with the J 41413-SPT.
* Individual components can be isolated and tested using adapters in the J 41413-300.
* A condition may exist where a leak in the EVAP system only exists under a vacuum condition. This type of leak may be detected by using
the scan tool Purge/Seal function to create a vacuum in the EVAP system and then observe the FTP parameter for vacuum decay.

DTC P0963
- Line Pressure Control (PC) Solenoid Control Circuit High Voltage
Diagnostic Fault Information
Circuit/System Description
The line pressure control (PC) solenoid is part of the control solenoid valve assembly which has no serviceable components. The normally high line
PC solenoid regulates and directs the PC solenoid oil pressure to the pressure regulator valve and isolator valve. Increasing line PC solenoid
pressure increases transmission line pressure. The transmission control module (TCM) varies the current to the line PC solenoid through a low side
driver. Decreasing the current to the line PC solenoid increases line PC solenoid oil pressure by closing OFF the solenoid exhaust port. Increasing
the current to the line PC solenoid decreases line PC oil pressure by opening the solenoid exhaust port. Line PC solenoid power is supplied by the
TCM through a high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is
detected, the HSD will turn OFF. When the fault is corrected the HSD will reset.
Conditions for Running the DTC
* The engine speed is greater than 400 RPM for 5 seconds.
* The ignition voltage is 8.6 volts or greater.

DTC P1A21
- Hybrid Battery Contactor Control Sequence Incorrect
Circuit/System Description
The drive motor generator battery control module is also referred to as the battery energy control module (BECM). The drive motor generator
battery control module will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is
communicated from the drive motor generator battery control module to the hybrid powertrain control module (HPCM) through serial data. The
hybrid powertrain control module is the host controller for diagnostic trouble code (DTC) information.
The hybrid powertrain control module controls the operation of the high voltage contactors through communication with the drive motor generator
battery control module. The hybrid powertrain control module utilizes a pulse width modulated (PWM) contactor system request circuit and
redundant serial data to command the high voltage contactors Open and Closed. Under normal operating conditions, the drive motor generator
battery control module opens and closes the high voltage contactors based only upon the hybrid powertrain control module command. This
diagnostic identifies when the drive motor generator battery control module has opened the high voltage contactors when the hybrid powertrain
control module is commanding them closed.
Conditions for Running the DTC
* The vehicle power mode is RUN.
* Ignition voltage is 9-18 V.
* The vehicle has passed a successful precharge and the high voltage contactors have been closed this ignition cycle.
* The hybrid powertrain control module is commanding the drive motor generator battery control module to keep the high voltage contactor
closed.
Conditions for Setting the DTC
The drive motor generator battery control module reports that the contactors are open when the hybrid powertrain control module contactor system
request circuit and the serial data message both indicate a closed request.

DTC Descriptor
DTC P1A21
- Hybrid Battery Contactor Control Sequence Incorrect
Circuit/System Description
The drive motor generator battery control module is also referred to as the battery energy control module (BECM). The drive motor generator
battery control module will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is
communicated from the drive motor generator battery control module to the hybrid powertrain control module (HPCM) through serial data. The
hybrid powertrain control module is the host controller for diagnostic trouble code (DTC) information.
The hybrid powertrain control module controls the operation of the high voltage contactors through communication with the drive motor generator
battery control module. The hybrid powertrain control module utilizes a pulse width modulated (PWM) contactor system request circuit and
redundant serial data to command the high voltage contactors Open and Closed. Under normal operating conditions, the drive motor generator
battery control module opens and closes the high voltage contactors based only upon the hybrid powertrain control module command. This
diagnostic identifies when the drive motor generator battery control module has opened the high voltage contactors when the hybrid powertrain
control module is commanding them closed.
Conditions for Running the DTC
* The vehicle power mode is RUN.
* Ignition voltage is 9-18 V.
* The vehicle has passed a successful precharge and the high voltage contactors have been closed this ignition cycle.
* The hybrid powertrain control module is commanding the drive motor generator battery control module to keep the high voltage contactor
closed.
Conditions for Setting the DTC
The drive motor generator battery control module reports that the contactors are open when the hybrid powertrain control module contactor system
request circuit and the serial data message both indicate a closed request.
Action Taken When the DTC Sets
DTC P1A21 is a Type A DTC.
Conditions for Clearing the DTC
DTC P1A21 is a Type A DTC.
Diagnostic Aids
* The drive motor generator battery control module will set Contactor System Status parameter to OPEN when the Contactor System Request
Circuit Command parameter percent duty cycle is 65-75 percent.
