3176 DIESEL TRUCK ENGINE OEM SYSTEMS Caterpillar

If the check engine light is on and the engine does not respond to changes in throttle position, the vehicle should be driven to a dealer ONLY if the oil pressure gauge indicates normal engine oil pressure.

If equipped, turn on the cruise on/off switch, operate the vehicle using the set/resume cruise control switch to raise and lower the engine rpm.

The cruise control mode is operational from 0 km/h (mph) up to the vehicle speed limit (VSL) when the 3176 control unit does not respond to changes in throttle position. Maximum engine rpm will be the programmed engine rpm at the vehicle speed limit (VSL). Cruise control must be reselected after each gear change.
