Outline
^ There are two on-board diagnostic functions: Condition Detection Mode, which indicates trouble in the system; and Operation Mode, which checks for and indicates correct operation of the input signals to the control module.
^ The two functions can be done by using either of the following methods:
1. Checking the output of the data link connector by using the SST (NGS set)
2. Checking the flashing pattern of the cruise set indicator light





Operation Order
Use Condition Detection Mode or Operation Mode or both to inspect the cruise control system. Either diagnostic function can be done before the other. If one diagnostic function does not locate the trouble, carry out the other function.
