  • Cruise Control
  • Historically, cruise control is a feature intended to benefit the driver. Cruise control takes away the need to constantly monitor speed and helps drivers avoid driving too fast and potentially receiving a costly citation. In trucking, however, adaptive cruise control focuses on safety and fuel economy. Whereas cruise control is simply an engine function, it is now a safety feature driven by ABS and safety component manufacturers.

    Adaptive cruise control is an example of why technician training is an ongoing initiative. The technology became much more prevalent in model vehicles, leading to the need for technicians to understand how to diagnose and repair adaptive cruise control and similar emerging safety systems. Examining JPRO connection data, we found that at least three adaptive cruise control faults quickly became top-ten occurring faults in the late These faults are common across a variety of makes and models, which led us to determine why a new system on new vehicles caused so many instances of a fault, both active and inactive.

    Additionally we examined the effects and complications caused by this fault. Due to their high occurrence rate, this fault effects telematics systems and remote diagnostics platforms. The overload of data can lead customers to believe their trucks are in worse condition than their actual state, or if a fleet manager is designated to receive alerts each time a fault arises, he or she may become overwhelmed by the system and not realize the benefits it offers. A major concern is that the fault can inhibit other functions on the truck.

    In some instances, a regeneration may be prohibited until the adaptive cruse fault is corrected and cleared. This can be a costly experience if the driver requires a forced regen on the side of the road to get the truck moving again. Rather than force it on site, or have one forced with an application like Tripvision Uptime, fleets may have to call a mobile repair service. For three or more years, the faults occurred at a high rate, yet are mostly seen by the owners of newer trucks and dealerships or service centers who perform warranty repairs.

    As these vehicles began to age, fleets with longer trade cycles and service centers that commonly repair trucks after warranty periods end will begin to experience this issue and must be prepared to solve the problem.

    Fortunately, in most instances the solution to the adaptive cruise control is simple and could even be applied roadside, assuming the driver is relayed the proper instructions. Unlike cruise control in the automotive industry, adaptive cruise control on trucks utilizes a control switch that remains enabled upon startup, assuming it was activated before the truck shut down. We found these faults were overwhelmingly triggered shortly after a truck powered on and reached a speed equal or greater than five miles per hour.

    With drivers stopping for food, fuel, sleep, or any other reason multiple times during a trip, the likelihood of adaptive cruise switch remaining in the on position while the truck went from shutdown to driving again was high. The repair is simple — turn off the adaptive cruise control switch before allowing the truck to reach the five-mph mark. For technicians, it is best practice to turn this switch off before pulling a truck into the bay, else he or she risks triggering a fault that could inhibit other functions needed while in the bay.

    However, this safety system may not be as enjoyable as when you have complete control of your vehicle. Understanding how to disable the OnGuard collision safety system is not rocket science.

It is a 2A fuse located at the top of the PDC box on the left side.

    After that, reverse the process used in opening the box to lock it back in place. Simply put the cover back in place and tighten up those two thumbscrews to hold it back in place. After locking the box back in place, turn the battery disconnect switches on and get the power restored again to the coach. The simple steps above provide a way out of how to reset OnGuard collision safety system.

    Ensure to keep the removed fuse in a place where you can always access it safely. This is important in case there is a need to go back to the way it used to be; then, you can easily pick up the fuse and fix it back. The guidelines above can also be helpful in understanding Meritor Wabco OnGuard troubleshooting. To successfully disable the mitigation system, first of all, press the two arrows up and down on display. Ensure to hold them as you turn on the key. After that, release the two arrows up and down keys.

    While the key is still on, you can start the motor without turning off the key; then, the collision mitigation will go off immediately. Q: How do you turn off distance warnings on Cascadia? To turn off the distance warning on Cascadia, simply engage the CNCL button, which regulates the speed of a car.

    When this button is pressed once, it enables the system. To disable it, press it again. Once the CNCL button is pressed to disable the distance warning, you will not have any issue with the warning again as you drive. Q: How do you disable collision mitigation? It is pretty easy to understand how to disable a collision mitigation system in a car without breaking a sweat.

    Then, press and hold the button for about 2 seconds. After 2 seconds or thereabout, the system will release a beeping sound and display a message in the MID. This is also helpful for those asking how to disable the collision mitigation systems in Peterbilt diagnosis. However, it may require a little more insight. Q: What is adaptive cruise fault?

    You can also see an expert auto mechanic. Also, note that the cruise control switch is the answer to those asking how to disable the Bendix wigman system. It only requires switching off the control system. Q: How do I turn off lane departure warning? So, to successfully put off the warning system, kindly find the lane departure alert LDA button first.

    The switch has a design that looks like a car veering off its lane. After locating the button, press it to turn on the system; then, press it again to disable the LDA system. Once this is done, the warning system will successfully turn off. The process is quite simple, when next you need to turn off the lane departure warning in your car, simply remember the button by design in the similitude of a vehicle veering off its lane. Final Words Manufacturers of different vehicles design several control systems to enable drivers to have a safe and satisfactory driving experience; however, sometimes, these systems can be boring and distracting.

    That is why this article has addressed the issue of OnGuard collision safety system. Kindly refer back to the step-by-step guide to digest the procedures properly. Learn more:.

    Operator switches are used to control vehicle speeds.

    How To Disable Onguard Collision Safety System?

    The feature offers flexibility for different vehicle setups and can be tailored to optimize fuel economy or performance in any application. This means both owners and operators benefit from its use. It gives you the freedom to take your foot off the pedal while maintaining vehicle speed. Accelerate to your desired vehicle speed and switch to the set position.

    Each bump will increase or decrease your speed by 1 MPH. The speed chosen must be between 30 and mph. This can have a positive effect on fuel consumption. This will allow a little reserve speed for passing situations that require the use of the accelerator pedal.

    They both have maximum vehicle speed and droop parameters. These parameters can be tailored to provide the desired combination of performance, economy, and speed control. The Upper Droop controls fueling as you drive up a grade or accelerate and the Lower Droop controls fueling as you drive down a grade.

    Cruise Control

    If the Cruise Control and Road Speed Governor Droop parameters are setup differently, the vehicle will perform differently while using cruise. The Cruise Control AutoResume feature allows the engine to resume "cruising" after a clutched gear change is made. It is important to remember that when this feature is active, tapping the clutch pedal will still disengage Cruise Control. The control system can differentiate between tapping and a normal clutched gear change.

    Cruise will only resume if the engine is sure the operator used the clutch for shifting purposes.
