Should I be worried? Why would that light be on? Compare Car Insurance.

The Honda Pilot's all-wheel-drive system is pretty clever, with variable torque distribution between its front and rear axles, as well as between the left- and right rear wheels. It generally works well and ensures strong traction on difficult roads - but some issues have been reported over the years. Their modes of operation are very similar, though, with the newer i-VTM4 essentially just adding more intelligence to the rear-axle torque distribution algorithms for improved agility and better stability in extreme driving conditions. But what if something goes wrong? First, let's look at what VTM-4 is. However, it's important to note that there is a clear distinction between the gauge-display-mounted VTM-4 or i-VTM4 warning light, and the confirmation light inside the dashboard-mounted VTM-4 switch, to the left of the audio system. The VTM-4 warning light in the Honda Pilot's instrument cluster should only illuminate when starting up the engine, following which it should extinguish within a second or so.

The benefits of the system are superior all-weather handling, exceptional performance in sand, snow, and mud, and neutral, accurate steering and handling under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems. Today i-VTM4 is available on Honda Pilot and Passport SUVs, and is standard on Ridgeline pickup, giving all all-wheel drive customers the peace of mind and capability that comes with the sophisticated system. The system progressively distributed optimum torque between the front and rear axles, and dynamically distributed engine torque between the left and right rear wheels. ATTS not only offered enhanced traction management similar to a limited-slip differential, but the active torque vectoring of overdriving the outside wheel helped significantly reduce understeer, giving the front-wheel drive Prelude Type SH handling characteristics more commonly associated with all-wheel drive cars. For the Acura MDX and Honda Pilot, engineers sought an all-wheel drive system that would automatically distribute torque to all four wheels as needed, but in a compact and lightweight package. During normal operation the clutches were disengaged, allowing the rear axles to freewheel, delivering all engine power to the front wheels. Mounted alongside the front transaxle, the torque-transfer unit receives torque from a helical gear that is attached to the front differential's ring gear. From there, a short horizontal shaft and hypoid gear set within the torque-transfer unit's case send power to the rear drive unit though a lightweight driveshaft. Controlling the torque split between the rear wheels are two hydraulically operated clutch packs, one for each rear wheel. The clutch packs are activated with an electric motor that powers a single hydraulic pump for each pack. The i-VTM4 Electronic Control Unit ECU controls a pair of linear solenoids by selectively sending pressure to the packs, which controls the amount of power sent to each rear wheel. Together, the clutch packs control the front-to-rear torque split, and when controlled independently, they can send all the rear-wheel torque to a single rear wheel. Determining how much torque to send to the rear wheels, and how much to distribute to the left and right, falls to the input of multiple sensors. The i-VTM4 ECU monitors steering angle, lateral g-forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts, while the engine ECU provides information on engine rpm, airflow and transmission gear-ratio selection, and the VSA ECU provides wheel-speed data.

Are you a proud owner of a Honda Pilot? This advanced technology enhances the performance and drivability of your Honda Pilot, especially during challenging weather conditions or off-road adventures. In this guide, we will walk you through everything you need to know about using the VTM-4 system on your Honda Pilot. The VTM-4 system is an intelligent four-wheel drive system developed by Honda. It works in conjunction with the Vehicle Stability Assist VSA system to provide enhanced traction and stability on various terrains. When engaged, it distributes torque between the front and rear wheels to optimize grip and prevent wheel slippage. Unlike traditional four-wheel drive systems, the VTM-4 system in the Honda Pilot is fully automatic and requires no driver intervention. It constantly monitors road conditions, wheel speeds, and steering input to determine the appropriate torque distribution.

The car feels low on power and shudders above 55 mph. The ECO light also doesn't turn on anymore. I did a quick search and this seems to be a code for an oil pressure switch on the firewall-side of the engine that deals with VCM. I'm hoping that throwing on a new switch will fix it and this isn't some serious VCM-related engine issue.

AVS Forum. The entire experience is seamless. Don't even try to keep driving. Toyota Rav4. When driving on a curving road in wet weather, i-VTM4 continues to help maintain maximum traction and stability by constantly adjusting how torque is routed. Compare renters insurance quotes. February 7, If it starts to flash pull over and turn off your engine. Furthermore, i-VTM4 uses input from the push-button-operated Intelligent Traction Management system to further refine the operation through four different modes: Normal, Snow, Mud and Sand.

Jerry partners with more than 50 insurance companies, but our content is independently researched, written, and fact-checked by our team of editors and agents. Conventional all-wheel drive systems seek a compromise between front and rear-wheel drive by routing power to the front and rear at the same time to increase stability. American Honda Collection Hall. Heated leather seats make it comfortable, but cheap plastic abounds in the interior of the Dodge Challenger. Intelligent Traction Management allows the driver to select the operating mode that best suits the driving conditions, altering i-VTM4, electronic throttle, transmission shift behavior and VSA using the following parameters:.
