Volvo trucks are the perfect vehicle for anyone who is looking to do more with their truck than just go from point a to point b.

Turn signals do not blink at all or blink quickly

Volvo trucks come equipped with a light control module which is responsible for controlling the lights on the vehicle and this includes the turn signals, brake lights, and so on.

Over time, there is a good chance that you may find that your Volvo truck’s turn signal is not working properly.

What you will find is that when you flip the switch to signal a right-hand turn you get nothing, or if you signal to go left then it may not work at all.

Another issue that you may find with your turn signal is that it may not work at all. If you’ve noticed a lot of bulbs going out on your Volvo truck, this could be the result of a failure in the light control module.

If you are an experienced mechanic and find that you can start to hear the bulb pop as well, then this could be the culprit.

This may not be a problem for you if your Volvo truck is just new, but you should take note of any lights that do not light up in the dash like the fuel gauge, temperature gauge, and so on.

If these lights were working properly, to begin with, and now they are not, chances are that this could be a result of the light control module.

Brake lights are inconsistent or have ceased working entirely

The brake lights on your Volvo truck are also controlled by the light control module. If you find that your brake lights are not working properly, this is definitely a sign that something is not right with your light control module.

About Light Control Module Volvo Truck

The light control module is for the lights and instrument panel on a Volvo truck. It controls the intensity, brightness, and direction of illumination.

The control module has a rocker switch with 2 positions; ON and OFF. There are also 3 round pushbutton controls around it that have the following functions:

next light (controls individual lights), left shade (controls left half of the center shade), and a right shade (controls right half of center shade).

In the VNL’s dashboard, the light control module is mounted on a metal plate. The wire harness is routed down to it and plugs into its connector.

The 3 pushbutton switches are located just left of the light control module. Two of them (left and right shade) are circular switches with indicators on them, while the last one (next light) is a small button located slightly lower than its predecessor.

Where Is the Light Control Module on A Volvo Truck?

The light control module is positioned just behind the VNL’s fuses in the middle of the dashboard. It may be behind one of the panels and will often be attached to a cable.

To find it, start by looking for the VNL’s fuses on either side of the dashboard. If there are no fuses on either side, then the light control module is most likely positioned at the back of a panel, underneath it, or just next to it.

The light control module is a small plastic box with wires coming out of it. It has the Volvo logo on the top of it and can be easily distinguished from other components on the dashboard.

On a few vehicles, there are two different-sized covers, which can be found on each side of the dashboard.

What Is the ACM In A Truck?

What Is the ACM In A Truck?

The ACM means Active Control Engine Mount in a truck. The Active Control Engine Mount is a device that’s used to isolate engine vibration.

This reduces stress on the remainder of the vehicle and increases the truck’s resale value. Recently, many manufacturers are starting to utilize the ACM in the passenger cabin to provide further isolation of the driver’s area.

Essentially, all it does is move the engine and power train away from the cabin. While this operates primarily as an anti-vibe device, it can have further benefits by lessening the impact of engine noise and vibration on passengers.

What Is A VEC Sensor on A Volvo Truck?

Volvo Enhanced Cruise (VEC) tracks up to 32 objects in front of the vehicle at distances of up to 500 feet using a radar sensor located under the bumper.

If a VEC-equipped Volvo detects an obstacle, the system provides for a gentle brake application, steering correction, or both.

The system is not yet available for production vehicles, but Volvo says it is a major step towards the automaker’s goal of implementing full-autonomy systems in its cars by 2019.

VEC is short for “Volvo Enhanced Cruise”.

What Is LVD In Volvo?

An LVD is a type of automated switch that enables truckers to use utilities and pleasure items throughout key-off times while maintaining the battery power required to start the engine.

Volvo has been a key player in the industry for a number of years, but they didn’t invent the idea of an LVD. There are many other types of automated switches and each brand has its own unique type.

However, Volvo’s LVDs is especially clever because they’re designed to keep an LVI from going out. Along with these so-called smart batteries, Volvo’s trucks have now made great strides in fuel economy.

What Does A Light Control Module Do?

The Light Control Module is in control of all of the vehicle’s lights. It performs a number of functions including controlling lighting levels, switching between daytime running lights and adaptive headlights, and controlling the position of the headlamp beams.

A Light Control Module is an integral part of any vehicle’s electrical system. It is the set of components that allows you to control the headlights, daytime running lights, fog lamps, and taillights. All vehicles with light-emitting diodes (LEDs) for lighting will have a Light Control Module.

In some vehicles, the Light Control Module is located in a box, as is common with vehicle safety equipment such as airbags and other critical systems.

In other vehicles, the module is incorporated into a circuit board with the appropriate connection points and may be mounted to the circuit board by adhesive or screws.

The function of a Light Control Module is to control all of the lighting functions which are usually accomplished by a bulb or circuit.

What Is SCR In Volvo Trucks?

What Is SCR In Volvo Trucks?

SCR is a sophisticated active emissions control technology that decreases exhaust nitrogen oxide (NOx) emissions to relatively close levels.

It works by injecting diesel exhaust fluid (DEF) into the exhaust stream, where it reacts with NOx to produce water vapor and harmless nitrogen gas.

This results in an 80-90% reduction in emissions of NOx, carbon dioxide (CO2), and other harmful pollutants such as particulates.

SCR is a Euro 6d-TEMP compliant technology and is a standard emission control system that can work in any climate where diesel fuel offers some degree of lubrication. It can also be used for other fuels such as biodiesel and NG, but it needs to be tuned for each fuel.
