Tip of the Month

How can a Customer regulate the Road Speed parameter settings?

In most cases there are (2) two levels of Road Speed settings. The Customer Road Speed (P1AOC) can be changed by Tech Tool and other tools. To better control the Road Speed setting use the Max Road Speed Limit (P1ALV or P1I09 on earlier vehicles). Only Tech Tool can change the Max Road Speed and the user ID is recorded. The other option is to activate the ECU password option.
