What Does Lowash Mean on a Dodge Ram: Unlocking the Power of this Indicator

What Does Lowash Mean on a Dodge Ram

When it comes to maintaining your Dodge Ram, understanding the warning lights and messages on your dashboard is crucial. One such warning message that you might come across is “Lowash.” If you’re wondering what Lowash means and why it’s important, you’ve come to the right place. In this article, we will explain the significance of the Lowash message on a Dodge Ram.

What is Lowash?

Lowash is short for “Low Ash,” and it refers to the ash content in the diesel particulate filter (DPF) of your Dodge Ram. The DPF is a crucial component of the vehicle’s emission control system, which helps reduce harmful exhaust emissions. Its main purpose is to capture and store soot particles produced by the engine, preventing them from being released into the atmosphere.

Over time, the soot particles accumulate in the DPF, leading to the need for regeneration. The regeneration process burns off the stored soot particles, converting them into ash. When the ash content reaches a certain level, the Lowash warning message is triggered on the dashboard of your Dodge Ram.

Why is Lowash Important?

The Lowash warning message is important because it indicates that the ash content in your DPF has reached a critical level. Ignoring this message can have serious consequences for the performance and longevity of your Dodge Ram.

When the ash content goes beyond the recommended level, it can lead to several issues:

  1. Reduced Fuel Efficiency: A clogged or blocked DPF can restrict the exhaust flow, causing the engine to work harder and consume more fuel.
  2. Loss of Power: A significant ash buildup can restrict the airflow through the DPF, resulting in reduced engine power and performance.
  3. Emission Non-Compliance: If the ash content exceeds the limit, your Dodge Ram may fail emission tests, making it non-compliant with environmental regulations.
  4. Potential DPF Failure: Excessive ash accumulation can lead to DPF failure, requiring costly repairs or replacement.

What to Do When You See the Lowash Message?

If the Lowash warning message appears on your Dodge Ram’s dashboard, it is essential to take immediate action. Here are the steps you can follow:

  1. Regeneration Process: Start by driving your Ram at a steady speed on open roads or highways for at least 20-30 minutes. This allows the DPF to reach the required temperature for regeneration, effectively burning off the stored soot particles and reducing the ash content.
  2. Visit a Service Center: If the Lowash message persists even after attempting the regeneration process or if it keeps reoccurring frequently, it’s recommended to visit an authorized Dodge service center. They have the necessary tools and expertise to diagnose and address any underlying issues with your DPF.
  3. Maintain Regular Service Schedule: To prevent the Lowash message from appearing, it’s crucial to follow your Dodge Ram’s recommended service schedule. Regular maintenance, such as oil changes and filter replacements, can help keep your DPF in optimal working condition.

Remember, taking prompt action and regular maintenance can help you avoid expensive repairs and ensure the longevity of your Dodge Ram.
