Pinpoint Test Ad: Stability System Active Too Long Concern
Normal Operation and Fault Conditions
The ABS module uses information from the wheel speed sensors, RCM and PSCM to determine when stability control intervention is necessary to help stabilize the vehicle. The ABS module uses the EBB unit (electric boosted vehicles) or the HCU (vacuum boosted vehicles) to modulate the brake fluid pressure to the brake calipers and continues to monitor the sensor and module input until the instability event has been corrected. Once the sensors and modules indicate the instability event has been corrected, the ABS module deactivates the EBB unit (electric boosted vehicles) or the HCU (vacuum boosted vehicles). Under inflated tires, wheels and tires that do not match VC label specifications, suspension and steering damage, and one or more sensor failures contribute to the ABS module setting this DTC.
DTC Fault Trigger Conditions

|---|---|---|
| ABS C006B:00 | Stability System Active Too Long: No Sub Type Information | Sets when the ABS module detects the ABSESC or RSC function has been active for longer than the various sensors indicate is necessary. |
