NOTE: This diagnostic trouble code applies only to ABS systems equipped with DSTC.

The pre-pressure valve in the brake booster sends a signal to the ABS control unit regarding the pressure in the braking system and the driver's intentions (if the driver depresses the brake pedal, the AYC control must be disconnected). If the control unit registers a faulty signal from the pre-pressure valve, diagnostic trouble code ABS-00B0 is set.

Substitute Value

Stabilizing function blocked.
