瀚慖f any listed DTC is present, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) to diagnose that DTC prior to this diagnostic.
2. Replace the K17 Electronic Brake Control Module (EBCM) and verify the DTC does not reset.
瀚慖f the DTC resets, replace the module that set the DTC.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Circuit/System Description
The camshaft position actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is
operating. The camshaft position actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the camshaft position
actuator solenoid duty cycle by controlling the amount of solenoid ON time. The camshaft position actuator solenoid controls the advance or the
retard of each camshaft. The camshaft position actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Conditions for Running the DTC
* DTC P0010, P0013, P0016, P0017, P0018, P0019, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 is not set.
* The engine speed is greater than 560 RPM.
* The engine is operating for greater than 1 s.
* The engine coolant temperature is between -48 to +143掳C (-54 to +289掳F).
* The engine oil temperature is less than -48掳C (-54掳F).
* The engine must accelerate such that the camshaft position actuator system is commanded from the park position to the phased position. This
is considered a cam control cycle. There must be a minimum of 2 cam control cycles for at least 2.5 s each in the phased position.
* DTCs P000A, P000B, P000C, P000D, P0011, P0014, P0021, and P0024 run continuously once the above conditions are met for greater than
