Retrieving Input Switch Codes
NOTE:
System input switch test should be performed if no trouble codes are stored when performing self-diagnostics. System input tests cycle each cruise control switch and sensor.
- Use scan tool or an analog voltmeter for code retrieval. Turn ignition off. Install scan tool or voltmeter. Turn ignition and cruise control SET switch on. Turn on cruise control main switch, and within one second, turn on RESUME switch.
- Operate each switch listed in INPUT SWITCH CODE IDENTIFICATION table and read input switch codes on scan tool or voltmeter. Repair or replace components as necessary.
