Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello & Welcome to JA,
Very good picture, these blue clips are connect assurance clips that make sure that connector is locked into place. Pull them straight out & then you can squeeze the connector lock to remove the connector.
This is the connector body you are working with.The outward clip is what is holding it. Use a small screw driver & flex it toward the connector to remove.
No,the blue clip that is removed keeps the lock of the connector from being unlocked.
You will need to insert the small screw driver beside this to press in the lock on th connector.
Neither , the locking clip is just below #2 / great pics.
Look closely at the connector & The small upper pic.
You want to unlock that outer lever to remove the connector.
I am sorry to hear that you have had so much problem,but I have seen a lot of problems with these vehicles. They are real cute vehicles ,but as in many new productions (in my opinion) they have not lived up to what I would consider a dependable vehicle,but that sometimes takes a few years to work the kinks out.
JA does not allow email so we can discuss this here.
Power Steering Control Module Programming and Setup
The Power Steering Control Module (PSCM) requires no programming or setup procedure. Most of the modules & computers do require programming ,but this one does not. The first path to repairing your power steering problem would be to scan the system for fault codes Here is a bulletin for some of the problems.
07-02-32-007B: Diagnostic Tips for Power Steering Inoperative/Steering Wheel Hard to Turn, Power Steering Message Displayed on DIC, DTCs C0176, C0475, C0476, C0550, U2105, U2107 Set - (Aug 6, 2009)
This bulletin is being revised to update the information for DTC C0475. Please discard Corporate Bulletin Number 07-02-32-007A (Section 02 -- Steering).
The following diagnostics might be helpful if the vehicle exhibits the condition(s) described above. Use the appropriate recommendation based on what symptom has occurred.
Review Corporate Bulletin Number 05-02-32-002D to assure you do not have a blown 60 amp steering fuse. The fuse can be blown during improper jump starting of the vehicle on the HHR and ION. Check for this particularly for tow in conditions. DO NOT replace the steering column unless an internal short has been identified in the column that is causing fuse to blow.
This condition is often the result of excessive lock-to-lock turns of the steering wheel, causing the thermal protection in the power steering control module (PSCM) to take the steering motor temporarily off line. This is a normal operating characteristic of the system. DO NOT replace the steering column for this condition. Refer to Corporate Bulletin Number 06-02-32-002C for additional information.
Inspect the motor harness connection to the PSCM. If no connector problems are found, replace the steering column ONLY as this is an internal controller issue.
Check the connection between the EPS motor and the power steering control module (PSCM) by ensuring the harness connector is properly seated. If the connection is normal, replace ONLY the EPS motor.
Note: If the DTC resets immediately following motor replacement, replace the steering column.
Although the code(s) appear in the PSCM, these are communication codes and are not the result of a problem with the column operation or the control module. If the codes are in history, clear the codes and re-key the vehicle a few times to see if they come back. If they reappear, look for a communication issue from the BCM U2107 or ECM U2105 (wiring, connector, etc.) as the root cause. If the codes do not reappear after a test drive, return the vehicle back to the customer. DO NOT replace the steering column.

Your speedometer not working, one would need to start with a fault code to begin the diagnosis. This can be a faulty VSS (vehicle speed sensor) ,wiring ,or computer.
If there is no vehicle speed sensor signal,this will cause a check engine light & the transmission to shift hard.
Here is a pic of the VSS for automatic trans.
Inspect the wiring very closely.Sometimes you will find the harness to be damaged ,causing the problem.
You are very welcome,I hope it all comes together for you.
The P0700 is a TCM (transmission control module code)
