The Road Relay 4 also shows 75 seconds of data that includes mph, engine rpm and the brake and clutch activity for the last three hard stops. The earlier Road Relays could only show the number of panic stops in the last trip. If the truck is equipped with this Road Relay option, the hard stop information is available for downloading.Ĭummins is on their fourth reiteration of this dash mounted display device and it is called the Road Relay 4.

This display is a sophisticated trip computer that can also advise the driver of engine related problems. The Cummins electronic fuel injected highway engines have had the option of a “Road Relay” dash mounted display since 1993. This device can be programmed to enable the driver to reset all the trip information with the exception of the quick stop data.

This diagnostic code event records oil pressure and temperature, coolant pressure and temperature and any faults in the electronic systems such as fuel injector faults, open circuits, etc.Ĭaterpillar calls their trip computer the “Cat Driver Information Display.” This unit is a sophisticated device that monitors such items as average fuel mileage, instant fuel mileage, trip time, trip distance and other information that can assist in accident reconstruction. The ECM also logs a diagnostic code event at the time the quick stop event is recorded. Any subsequent quick stop events will replace the oldest one that is stored. It will record the engine hours, engine rpm, throttle position, clutch switch position, brake switch position, cruise control status, and vehicle speed for 44 seconds before the event and 15 seconds after the event in one-second intervals. An internal battery backs up the RAM memory and the stored information will remain in the memory for seven to ten years. although Caterpillar recommends a setting of 7 mph/sec.Ī quick stop event will be recorded in the RAM memory of the ECM if the threshold setting is reached.

The available settings are from 0 to 15 mph/sec. It can be set by the chassis builder, by the selling dealer, or occasionally, by the end user. The quick stop is set at a deceleration rate of 0 mph/sec./sec. The quick stop feature became available in November of 1995. The following is a brief overview of what information is available.Ĭaterpillar began installing electronic engine controls in 1993.Ĭaterpillar refers to a hard stop as a “quick stop” in their software. The information that can be retrieved from the engines electronic control module (ECM) varies from year to year and the manufacturer of the engine. These features began as simple trip recorders and evolved into the sophisticated systems that we have today. As the systems became more sophisticated, the engine manufacturers began adding features at the request of the equipment purchasers. The electronic engine controls were initially used to control the diesel fuel injection systems that were being installed to meet more stringent federal emission requirements.
