Understanding Code 46 in Detroit Engines

If you own a Detroit diesel engine, especially the 12.7 or 14-liter models (or even the 11.1), you might come across the dreaded Code 46. 

This code indicates a significant problem that requires immediate attention to ensure your engine continues to operate smoothly.

What does code 46 mean?

Code 46 typically points to issues with the engine’s internal components, specifically related to the internal battery. Recognizing this code early can save you from more serious complications down the road.

Consequences of a blown battery

A blown battery can cause acid leakage, threatening the engine’s electronic control module (ECM) and potentially leading to irreparable damage. 

Ignoring this issue may result in costly repairs or engine failure while on the road. Taking proactive measures can prevent further damage and keep your truck operational.

Repair or replace?

When faced with Code 46, you essentially have two options: repair the battery or replace it entirely. Acting swiftly can help you avoid more extensive damage and save you from expensive repairs later on.
