Input Switch Code Inspection

System input tests should be performed if no DTCs are stored when performing self-diagnostics. System input test cycles each cruise control switch and sensor.
Turn ignition off. Connect scan tool or voltmeter to DLC. Turn ignition on. While holding cruise control switch in SET/COAST position, depress end of switch to ON position. Within one second, move switch up to RES position.
Operate each switch listed in CHECK RESULTS CODE IDENTIFICATION table, and read input switch codes on scan tool or voltmeter. Repair or replace components as necessary.
