Selector Switch Test (Response Code 1-1-3)
- Response Code 1-1-3 is obtained when selector is switched from OFF to ON, ON to OFF, or if brake or clutch pedal is depressed while selector is set to ON. If code cannot be obtained in any position, voltage is either constantly high (12 volts) or low (zero volts). If Codes 1-3-1, 1-2-3, or 2-1-3 are also present, there is voltage to selector switch. Go to BRAKE & CLUTCH PEDAL CHECK (RESPONSE CODE 1-1-3). If Codes 1-3-1, 1-2-3, or 2-1-3 are not present, go to next step and check voltage supply to selector switch.
- Check cruise control fuse No. 28 and replace as necessary. If fuse is okay, remove upper and lower steering column covers. Check voltage to cruise control selector switch by turning ignition on. Connect voltmeter (backprobe) between selector connector terminal No. 2 (Blue/Yellow wire) and ground. See Figure. If battery voltage is not present, check selector wiring. If battery voltage is present, go to next step.
- Connect voltmeter (backprobe) between selector connector terminal No. 1 (Gray/White wire) and ground. Put switch in ON position. If battery voltage is not present, replace selector switch. If battery voltage is present, selector switch is okay.
