Circuit/System Description
The power steering control module (PSCM) continuously monitors the torque sensor input and output shaft sine wave frequency signals. As the steering wheel is turned and torsional twist is applied to the steering column shaft, the torque sensors input and output shaft sine wave frequency signals are processed by the PSCM to detect and calculate the steering torque.
Conditions for Setting the DTC
The PSCM detects open, short to ground or short between any of the torque sensor circuits.
Actions Taken When DTC Sets
• DTC C0545 is stored in memory.
• The driver information center (DIC) displays the SERVICE POWER STEERING warning message.
• No steering assist.
DTC C0550 00: EEPROM Checksum Mismatch . Your best bet , take your vehicle to a qualified repair shop.
Circuit/System Description
When the ignition is turned ON, the microprocessor runs a diagnostic program to detect an internal fault when power up is commanded. If an internal malfunction is detected, the control module will store a DTC C0550 in its memory.
Action Taken When the DTC Sets
If equipped, the following module specific actions may occur:
• The antilock brake system (ABS) indicator turns ON.
• The BRAKE warning indicator turns ON.
• The electronic brake control module (EBCM) disables the ABS/dynamic rear proportion (DRP)/traction control system (TCS).
• The driver information center (DIC) displays the power steering warning message No Steering Assist.
• The TCS indicator turns ON.
Check your engine oil using the oil dipstick located on the engine - you need to add oil to the fill line as shown on the dipstick. You should have the oil replaced regularly (every 3-6 months) and keep your eye on the level if the engine is leaking oil underneath or burning a lot of it.
If the system fails to turn on or activate, the StabiliTrak light along with one of the following messages will be displayed on the Driver Information Center (DIC): TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, STABILITRAK OFF, SERVICE STABILITRAK. If these DIC messages appear, make sure the StabiliTrak system has not been turned off using the StabiliTrak on/off button. Then turn the steering wheel clockwise from the nine o'clock position to the three o'clock position. If this clears the message(s), the vehicle does not need servicing. If this does not clear the message(s), then turn the vehicle off, wait 15 seconds, and then turn it back on again to reset the system. If any of these messages still appear on the DIC, the vehicle should be taken in for service.
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the left of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the
shift lever position indicator. See Automatic
Transmission Operation on page 3-23 for more
information.
If your vehicle’s DIC has these features, the compass
direction and the outside air temperature may also
display on the DIC when viewing the trip and fuel
information. The compass direction appears on the top
right corner of the DIC display. The outside air
temperature automatically appears in the bottom right
corner of the DIC display. If there is a problem with the
system that controls the temperature display, the
numbers will be replaced with dashes. If this occurs,
have the vehicle serviced by your dealer/retailer.
The DIC also allows some features to be customized.
See DIC Vehicle Customization on page 4-66 for
more information.

This is a known problem with the power steering which will probably require replacement of the power steering motor. The HHR uses an electric 12V DC motor to provide the power steering force, and they have started failing.
GM is recalling the Cobalt and other vehicles for this issue, but not yet the HHR. If you are out of warranty, you will probably be personally responsible for the cost of diagnostics and replacement.
You will probably need to contact your dealer unless you are able to replace the motor yourself. Sorry.
oh thats the change oil light expect it every 3500 to 4500 miles they glow.. you can usually reset it by holding down the trip button with the car off and then turn the key to the II position where everything lights up
