Pinpoint Test O: DTC U3000:63

Normal Operation

The adaptive cruise control system is enabled when the vehicle speed is set and the Cruise-Control Module (C-CM), which is a radar unit, determines the distance and relative speed of the vehicle that is in the path of travel. The C-CM commands the ABS module over the High Speed Controller Area Network (HS-CAN), which controls the brakes, to automatically apply the brakes to slow the vehicle to maintain a safe distance to the vehicle in front. The brake lamp control circuit is pulled low by the ABS module which controls the brake lamp relay. This activates the brake lamps when the brakes are applied for the adaptive cruise control system.

- DTC U3000:63 (Control Module: Circuit/Component Protection Time-Out) - set by the C-CM as a continuous memory and on-demand DTC if the C-CM detects too many collision mitigation by braking activation requests.

This pinpoint test is intended to diagnose the following:
