Summary
This preliminary bulletin provides a procedure to reprogram the power steering module to correct the customers concern of the MIL on and a drop in power steering assist.
Condition/Concern
Malfunction Indicator Lamp (MIL) on and a drop in power steering assistance.
DTC C0544 with fault byte 5A and/or DTC U0415 with fault byte 75 set that does not clear.
DTC C0544 with fault byte 5A and/or DTC U0415 with fault byte 75 sets and does not clear if the Steering Angle Sensor alignment procedure is performed incorrectly. If the car is driven in this condition, as speed increases the driver will experience the car attempting to steer to the left or right (depending how which offset to left or right was set during the alignment procedure).
While steering at low speeds (parking lot), the driver will experience power steering assist for only a fraction of a turn left or right (dependent on offset) and a drop in power steering assist (full manual steering).

Reprogramming
GM Diagnostic/Programming (TIS2Web)
Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.
To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.
You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.
The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.
The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.
The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.

Service Bulletin File in Section: – Bulletin No.: PI0800D Date: December, 2014 PRELIMINARY INFORMATION Subject: DTC C0544 and/or U0415 Set and Will Not Clear, Malfunction Indicator Lamp (MIL) On Models: 2013 Buick LaCrosse, Regal (RPO NJ1) 2012 Chevrolet Volt Built After VIN Breakpoint CU119678 2013 Chevrolet Equinox 2013 Chevrolet Malibu (RPO NJ1) 2013 GMC Terrain Equipped with Electric Power Steering This PI has been revised to update step 7. Please discard PI0800C. Condition/Concern Some customers may comment on a Malfunction Indicator Lamp (MIL) on and a drop in power steering assistance. Technicians may find DTC C0544 with fault byte 5A and/or DTC U0415 with fault byte 75 set that does not clear. DTC C0544 with fault byte 5A and/or DTC U0415 with fault byte 75 sets and does not clear if the Steering Angle Sensor alignment procedure is performed incorrectly. If the car is driven in this condition, as speed increases the driver will experience the car attempting to steer to the left or right (depending how which offset to left or right was set during the alignment procedure). While steering at low speeds (parking lot), the driver will experience power steering assist for only a fraction of a turn left or right (dependent on offset) and a drop in power steering assist (full manual steering). Recommendation/Instructions To clear the DTC(s), it will be necessary to flash the Electric Power Steering Control Module (EPS) to a different software. • Identify DTC C0544 DTC with fault byte 5A and/or DTC U0415 with fault byte 75 is set. • Try to clear the DTC(s) with the service diagnostic tool. • Confirm DTC C0544 and/or DTC U0415 is still set as current. To reprogram the Electric Power Steering Control Module (EPS), follow the procedure below: 1. Verify the battery voltage is more than 12 volts but less than 16 volts before proceeding with reprogramming. The battery must be fully charged BEFORE reprogramming a control module. 2. During reprogramming, the battery voltage must be maintained within the proper range of 12-15.5 volts. CONNECT the approved Midtronics® PSC 550 Battery Maintainer (SPS Programming Support Tool (EL-49642) to the vehicle or the GR8 (EL50313) in the power supply mode. Notice: It is essential that the TIS terminal, MDI, Tech 2® and/or Scan Tool are updated with the latest software available. 3. Verify that the devices being used are updated with the latest available software version BEFORE beginning the reprogramming event. 4. BEFORE beginning reprogramming you MUST refer to Control Module References in SI for the appropriate Programming and Setup procedures. 5. If a wireless connection will be used for reprogramming, a secure service department connection MUST be used. DO NOT use any public WiFi connection from the customer lounge. 6. Reprogram the Electric Power Steering Control Module with the special VCI number provided by the Techline Customer Support Center (TCSC). Contact TCSC for instructions. Use Service Programming System (SPS) with the latest calibrations available on TIS2WEB. Refer to the SPS procedures in SI. 7. When the Electric Power Steering Control Module (EPS) VCI reprogramming is complete, clear codes, key off ignition, open and close door and allow vehicle’s network bus to go to sleep (wait 3 minutes). 8. Place ignition into Run (engine not running) power mode. 9. Reprogram the Electric Power Steering Control Module (EPS) again using Service Programming System (SPS), selecting “Replace and Reprogram” then selecting EPS programming in Support Controllers. 10. After reprogramming is completed, key off ignition, open and close door, allow vehicle’s network bus to go to sleep (wait 3 minutes). 11. Start the car. 12. Perform the steering angle sensor centering and steering endstop learn procedure. Refer to the Steering Angle Sensor Centering and Software Endstop Learning within Power Steering Control Module Calibration in SI. 13. Turn off the vehicle and let the Electric Power Steering Control Module (EPS) go to sleep (3 minutes). 14. Start the vehicle and perform a diagnostics check. The DTC C0544 and/or DTC U0415 should no longer appear. 15. Test drive the vehicle.
