Attention:
Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS. If the customer has not commented about this condition or the EI does not show in GMVIS, disregard the bulletin and proceed with diagnostics found in published service information. THIS IS NOT A RECALL -- refer to Service Bulletin 04-00-89-053B for more details on the use of Engineering Information bulletins.
Condition
Important
If the customer did not bring the vehicle in for this issue, DO NOT proceed with this bulletin.
Some customers may comment that the power steering is inoperative or the vehicle is hard to turn. This condition may have been noticed immediately after the vehicle was jump started.
Cause
GM Engineering is attempting to determine the root cause for the concern of the Electric Power Steering (EPS) system fuse blowing. GM Engineering has a need to obtain information first hand during the diagnosis and repair. As a result, this information will be used by Engineering to "root cause" the customer's concern and develop/validate a field fix.
Instruction
Important
Do not replace the 60 amp EPS fuse until all requested steps have been followed.
Before diagnosing the vehicle, discuss with the customer if the vehicle was recently jump started and by whom (i.e. customer, roadside service, etc.)
Important
DO NOT remove or replace the fuse at this time.
1. Verify the condition. Note the condition and continue.
2. Check if DTC C0176 is set.
3. Visually check if the 60 amp EPS fuse is blown. Do not remove the fuse to verify.
4. Look for visible signs at the EPS bolt at the UBEC location for attempts at jump starting. Note the condition and continue.
5. Proceed to the vehicle interior and inspect the EPS harness from the EPS pass-thru grommet to the two-way connector at the EPS unit and look for any trapped, pinched or chafed wires. Note the condition, but do not repair at this time. Continue to the next step.
6. Proceed to the exterior and review the routing of the EPS harness from the UBEC to the grommet pass-thru fro the same conditions listed in Step 5. Note the condition, but do not repair at this time. Continue to the next step.
7. Contact a GM engineer for further instructions. Have all of the above information available when contacting the engineer.
If the engineer is unable to take your call, please leave the following information in a message:
- Technician name
- Dealer name and phone number
- Complete vehicle VIN and Repair Order (RO) number
If the engineer is unable to return the call within one hour, proceed with the diagnosis and repair based on information found in SI.
