#PIE0070B: EI10105-Engineering Information-Electronic Stability Control (ESC) Message Displayed in Driver Information Center (DIC), DTC C0460 Set - (Aug 4, 2010)


Subject: EI10105 -- Engineering Information --Electronic Stability Control (ESC) Message Displayed in Driver Information Center (DIC), DTC C0460 Set


Models: 2009-2010 Chevrolet HHR

Equipped with Electronic Traction Control (RPO NW9)


Attention: Proceed with this PI ONLY if the customer has commented about this concern AND the EI number is listed in GWM IVH. If the customer has not commented about this condition or the EI does not show in GWM IVH, disregard the PI and proceed with diagnostics found in published service information. THIS IS NOT A RECALL -- refer to Service Bulletin 04-00-89-053C for more details on the use of Engineering Information PIs.

--------------------------------------------------------------------------------
This PI is being revised to update the Instructions. Please discard PIE0070A.
--------------------------------------------------------------------------------

Condition
Important: If the customer did not bring their vehicle in for this concern, DO NOT proceed with this PI.

Some customers may comment that the Service Electronic Stability Control (ESC) message appears in the Driver Information Center (DIC).

Cause
GM Engineering is attempting to determine the root cause of the ESC message. Engineering has a need to gather information on vehicles, PRIOR to repair, that may exhibit this condition. As a result, this information will be used to "root cause" the customer's concern and develop/validate a field fix.

Instructions
Note: This EI is only concerned with those cases where the DTC C0460 is responsible for the service ESC message. Multiple DTCs may be present, but C0460 must be one of them.

For first time occurrences of this condition to correct DTC C0460, refer to Brakes-Antilock Brake System-Diagnostic Information and Procedures in SI. Follow the procedure ending with Steering Angle Sensor Centering and clearing the DTCs. Road test the vehicle to ensure that steering angle is reading correctly. Call the engineer listed below for additional information if required.

If the vehicle has returned to the dealership for service for the same issue more than once, and before any codes are cleared, capture a snapshot (F3 on EBCM menu) of the EBCM VSES Data with a manual trigger and the trigger point set to end. Make sure to record the enhanced DTC data for each code set after driving the vehicle at 88 km/h (55 mph) or more in a relatively straight stretch of road for a minute. E-mail the snapshot file to dave.orth@gm.com. For instructions on emailing snapshots, refer to Corporate Bulletin Number 07-07-30-010B. Please call the engineer listed below for further instructions.

Below is additional information about C0460 set in the EBCM for HHR vehicles equipped with ESC (VSES).

The steering angle sensor (SAS) is a relative sensor and requires a two stage initialization that happens at each ignition cycle. The first stage is accomplished when the steering wheel is moved a few degrees in either direction (the steering angle will jump from the default value to the true value when this is complete). The second stage of the initialization happens usually when the vehicle speed reaches 15-20 km/h (9-12 mph) if the vehicle is driven in a straight line (when complete, the VSES Failed value found under VSES data changes from yes to no).

The EBCM automatically adjusts the steering angle when the vehicle is driven to compensate for a steering angle that is not zero when the vehicle is driven in a straight line. This steering angle can be adjusted up to 15 degrees without setting a DTC.

Common Causes for Particular C0460 DTC Symptom Codes:

Symptom Code 4B
This is commonly set when there is a short or open circuit present when the vehicle is keyed up. The fault will no longer be current if the short is not present at a later ignition cycle. This scenario usually also sets one or all of the following DTCs: U2142, U2143, U1500, C0292 39. A chaffing point has been identified on some vehicles on the harness on the female side of the X203 connector about 101 mm (4 in) from the connector.
This is also set when a new SAS has been installed. If a new sensor is installed it will be necessary to perform the SAS centering (calibration) procedure before the fault will clear.

Symptom Code 42
This code can be set if there are tires with different rolling diameters or there is a problem with a wheel speed sensor. Taking a snapshot of the VSES data while driving the vehicle in a straight line at highway speeds is a good way to identify this condition. Wheel speeds should be within 1.6 km/h (1 mph) in those conditions.
This code can also be set (sometimes in conjunction with the 5A symptom code) if the steering angle is not reading 0 when driving the vehicle in a straight line. If this is the case, perform the SAS centering (calibration) procedure.

Symptom Code 5A
The most common cause of this fault is identified by checking the enhanced DTC information item 4 DTC Subcode. If the value of the subcode is 20, then the EBCM has attempted to adjust the steering angle more than the 15 degree limit. This fault cannot be cleared unless a SAS centering (calibration) procedure is done first. By performing the calibration you will have also provided a new reference point for the 15 degrees of allowable adjustment. It is a good idea to test drive the vehicle to ensure that the steering angle reads 0 after the centering procedure is done to ensure there are no steering wheel alignment issues. If an alignment is required the centering procedure and test drive should be performed after the alignment.

Symptom Code 72
This most common cause of this code is a short or open circuit that occurs after the vehicle has been keyed up. This scenario usually also sets one or all of the following DTCs: U2142, U2143, U1500, C0292 39. A chaffing point has been identified on some vehicles on the harness on the female side of the X203 connector about 101 mm (4 in) from the connector.

Symptom Code 71
This code can be set if the steering angle sensor has been damaged internally and is often set in conjunction with the 72 symptom code.

Note: If the SAS Centering (calibration) procedure will not complete, it can be due to a damaged sensor or a sensor that will not communicate with the EBCM. It could also be due to an open or short circuit in the wiring.

#11-05-25-001: Electronic Stability Control (ESC) Message Displayed in Driver Information Center (DIC), DTC C0460, C0280 or C0196 Set - (Mar 30, 2011)


Subject: Electronic Stability Control (ESC) Message Displayed in Driver Information Center (DIC), DTC C0460, C0280 or C0196 Set


Models: 2009-2011 Chevrolet HHR Equipped with Engine RPO LE8 or LE9

Equipped with Electronic Stability Control System (RPO JL4)
--------------------------------------------------------------------------------

Condition
In rare cases, customers may comment that the Service Electronic Stability Control (ESC) message appears in the Driver Information Center (DIC) and/or the ESC system activates (modulates brakes and/or limits engine torque) at inappropriate times.

When diagnosing the condition, the technician may find Diagnostic Trouble Code (DTC) C0460, C0280 or C0196 Set.

Cause
This condition may be caused by the steering angle being inadvertently recalibrated. The condition may also be the result of the steering angle sensor (SAS) not being properly centered after an alignment or other repair.

The amount of steering deviation from the proper center location and the type of driving conditions encountered will determine which DTC or DTCs will set. The known DTCs that can be set by this condition are: C0460 5A, C0460 42, C0280 and C0196.

Correction
Use the following steps to correct the condition:

Use SPS to update the EBCM software. Technicians are to reprogram the EBCM using the Service Programming System (SPS) with the latest software currently available in TIS2WEB.
Recalibrate the SAS. Use the scan tool to recalibrate the SAS (see EBCM/special functions for Non-SS) in SI.
When using a Tech 2® or a Multiple Diagnostic Interface (MDI) for reprogramming, ensure that it is updated with the latest software version.

During programming, the battery voltage must be maintained within the proper range of 12-15 Volts. Only use the approved Midtronics® PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
