Electronic Brake Control Systems - Max-TRAC Traction Control System: Description: Notes

CHANGES, CAUTIONS, CORRECTIONS 

• MAX-TRAC OPERATIONAL NOTE  - System is designed to improve vehicle control during acceleration  , when road conditions are such that rear wheels may tend to spin while accelerating. This is a separate system and does not  operate during brake application. On 1973 models, system is designed to operate at ZERO MPH (1971-72 systems did not operate under TWO MPH). It is necessary to switch the system "OFF" when performing any service that requires spinning rear wheels.
• MOBILE RADIO EQUIPMENT NOTE:  If a telephone, citizens band radio or other transmitting device is installed, antenna or antenna lead wire must be at least three feet away from controller (to avoid possibility of signal interference which could cause Max-Trac to operate when not desired).

Purpose of system is to aid driver in maintaining directional stability and maneuverability during acceleration and/or cornering by automatically limiting engine power to value required for maximum acceleration without excessive rear wheel slippage. System uses ignition switch, stop light switch, stop light, ignition circuit, and consists of four major components:
