This filing is one of 10 Toyota notifications from 1998 in this archive.

Issue
The brake assist system — which reduces brake pedal effort during hard braking — contains a defectively manufactured sensor that detects brake pedal depression. The defect causes brake assist to activate during normal braking operations, applying greater braking force than the driver intended.
Corrective action
On all vehicles, the sensor serial number is verified and, where applicable, the sensor is replaced with a conforming part.
