Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
| Variable Effort Steering Actuator Supply Voltage | C0450 02 | C0450 0B | C0450 02 | C0450 0B |
| Variable Effort Steering Actuator Control | C0450 02 | C0450 0B | C0450 02 | C0450 0B |
Circuit/System Description
The electronic brake control module (EBCM) controls the current through the Variable Effort Steering (VES) actuator located on the steering gear. The current used to control the VES actuator is between 0 and 1 Amp. At low speeds and in parking lot maneuvers the current is applied to the actuator causing the orifice to open increasing fluid flow and reducing the steering effort. At high speeds the orifice is commanded closed by reducing current through the actuator and restricting fluid flow increasing steering effort. The EBCM monitors and compares the Commanded and Feedback Current parameters to detect malfunctions in the VES system.
Conditions for Running the DTC
- The ignition is ON.
- Ignition voltage is greater than 8 volts.
C0450 0B
The actuator current exceeds 150mA.
C0450 02
If the solenoid feedback voltage is greater than 80 percent while the actuator is commanded ON.
Action Taken When the DTC Sets
- The driver information center (DIC) will display SERVICE POWER STEERING message.
- Vehicle speed will be limited to 80 mph.
Conditions for Clearing the DTC
- The condition for setting the DTC is no longer present and the DTC is cleared with a scan tool.
- The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
Diagnostic Aids
The vehicle may need to be driven to view full VES Actuator Commanded and Actuator Feedback Data parameters.

Circuit/System Testing
| IMPORTANT | It is recommended that Component Testing is performed before Circuit/System Testing when diagnosing the VES actuator because the module will default and does not supply voltage to the sensor when the DTC is set. |
- Ignition OFF, disconnect the harness connector at the VES actuator. IMPORTANT: In order to ensure correct test results, the J-35616 test lamp must be used to perform the following steps. Failure to use the J-35616 test lamp may result in inaccurate test results and potential misdiagnosis.
- Ignition ON, verify that a test lamp illuminates between the control circuit terminal 1 and ground. If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance.
- Ignition OFF, connect the test lamp between the control circuit terminal 1 and the control circuit terminal 2.
- Ignition ON, verify the test lamp briefly illuminates for approximately 1 second, then turns OFF. If the test lamp is always ON, test the control circuit terminal 2 for a short to ground. If the circuit tests normal, replace the EBCM. If the test lamp is always OFF, test the control circuit terminal 2 for a short to voltage or an open/high resistance. If the circuit tests normal, replace the EBCM.
- If all circuits test normal, test or replace the VES actuator.
Component Testing
- Ignition OFF, disconnect the VES actuator harness connector terminal 1 and 2.
- Measure for 2.5-10 ohms of resistance between the VES actuator terminals. If not 2.5-10 ohms of resistance, replace the VES actuator.
- Measure for infinite ohms of resistance between each VES actuator terminals and the VES actuator housing. If less than the specified range, replace the VES actuator.

The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive, cam-driven.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir
- Mounted to the front of the dash panel
- Mounted to the inner fender
- Mounted to a bracket on the engine
The 2 basic types of power steering gears are listed below
- A recirculating ball system
- A rack and pinion system
In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft. A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod move the other tie rod.
In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the direction of the vehicle's front wheels.
The power steering pressure hose connects the power steering pump union fitting to the power steering gear and allows pressurized power steering fluid to flow from the pump to the gear.
The power steering return hose returns fluid from the power steering gear back to the power steering fluid reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid cooler.
In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the right and left chambers in order to assist in right and left turns.
Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to 1 side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or left.
Variable Effort Steering System Description and Operation
The variable effort steering (VES) system varies the amount of effort to steer the vehicle as wheel speed changes or lateral acceleration occurs. The electronic brake control module (EBCM) controls an actuator located in the steering rack and pinion. The actuator consists of an electromagnetic coil and a normally open pintle valve. The valve regulates an orifice that bleeds inlet pressure through a return passage to regulate the amount of pressure available for steering assist. The EBCM commands current from 0-1 amp to the VES actuator which varies the amount of effort required to steer the vehicle. At low speeds, 1 amp of current is commanded to the VES actuator and the pintle valve is fully closed which provides maximum pressure and maximum steering assist for easy turning and parking maneuvers. As speed increases, current is decreased and the pintle valve opens the orifice, decreasing available pressure providing firmer steering and directional stability. The VES system uses the steering wheel position sensor input to calculate lateral acceleration during abrupt driving maneuvers. The system also uses the antilock brake system (ABS) wheel speed sensor inputs to determine vehicle speed. The EBCM is constantly monitoring these inputs to achieve the desired current to the VES actuator. The EBCM has the ability to detect malfunctions in the VES actuator or the circuits to the actuator. Any malfunctions detected will cause the VES outputs to be disabled, and the actuator will return to an open state. The EBCM will command the driver information center (DIC) to display the SERVICE STEERING SYS warning message via the high speed GMLAN serial data circuit.
