System Coverage and Components
The documentation details the technical specifications for the accelerator control system and the full suite of cruise control electronics. Inside, you will find component breakdowns for the accelerator wire, bracket, and pedal assembly. It outlines the mechanics behind the vacuum pump, air valve, and release valve components responsible for maintaining set vehicle speeds. Furthermore, the manual breaks down the Intelligent Cruise Control (ICC) sensor aiming parameters, laser beam adjustment metrics, and vehicle-to-vehicle distance control diagnostics using the CONSULT-II interface.
Specification and Calibration Data
Precise reference values drive accurate diagnostics. This manual provides comprehensive torque charts for the accelerator and ASCD actuator components, ensuring exact mechanical tolerances during assembly. For electrical troubleshooting, it lists terminal reference values for the ICC control unit, radar sensor, and warning chime circuits. Pinout tables and continuity requirements help verify signal integrity across the CAN communication line and ASCD pump circuits. Pedal assembly and cable bracket torque values are documented in both Nm and lb-in units. Because working on advanced driver-assist systems involves complex electronics, these reference materials are intended for certified technicians equipped with proper diagnostic tools to maintain critical vehicle safety standards.
