What to Do When the Check Engine Light Comes On: A Guide for Hino Truck Drivers

The check engine light is a crucial warning system in your Hino truck. It indicates that there's an issue requiring attention, ranging from minor to serious problems. Here's a step-by-step guide on what to do when this light illuminates on your dashboard.

Step 1: Stay Calm and Assess the Situation

• Immediate Reactions: Don’t panic. The check engine light doesn’t necessarily mean your truck is about to break down. It’s a warning to alert you to an issue that needs attention. 

• Observe Symptoms: Check if there are any noticeable changes in your truck’s performance, such as strange noises, vibrations, or loss of power.

Step 2: Check for Obvious Issues

• Fluids and Levels: Check your engine oil, coolant, and other fluid levels. Low levels can trigger the light.

• Electrical Connections: Inspect for any obvious loose or damaged wires in the engine compartment.

• Visually Inspect Any Obvious Items: Inspect for any obvious broken or seized engine components like pulleys or belts

Step 3: Pull Over Safely

• If the check engine light is flashing, pull over safely as soon as possible. A flashing light indicates a serious problem that could damage the engine.

• Find a safe spot to stop and turn off the engine. Continuing to drive could exacerbate the issue.

Step 4: Evaluate the Severity - Contact Somerville Hino Service

• The professionals can absolutely help. Call the service department and talk to them about what's going on. Most of the time we can advise on minor or major issues just by a conversation over the phone.

• Minor Issues: If the code indicates a minor issue and the truck is running smoothly, you might be able to continue driving to a nearby service station.

• Serious Issues: If the code points to a serious problem, or if the truck is performing poorly, it’s best to call for professional assistance.

Step 5: Address the Problem

• Temporary Fixes: For minor issues like a loose gas cap, tighten it and see if the light goes off after a few engine cycles.

• Professional Help: For more serious issues, Somerville Hino has qualified mechanics. They have the expertise and tools to diagnose and fix the problem correctly and back on the road quickly. Book a service today!

• Monitor Performance: Pay attention to how your truck drives and any changes in performance. Early detection of issues can prevent the check engine light from coming on.

• Use Quality Parts and Fluids: Ensure that you’re using high-quality parts and fluids that meet Hino’s specifications.
