Honda A123 Service: Checklist & Maintenance Cost

What Is Honda A123 Service?

Honda vehicles come with a maintenance minder system that displays service codes when routine maintenance is due. One such code is A123, which indicates a combination of essential services needed to keep your Honda running smoothly.

Each letter and number in the A123 service code represents a specific maintenance task:

A – Engine oil change
1 – Tire rotation
2 – Replace air filter, replace cabin air filter, inspect drive belt
3 – Replace transmission fluid

Honda’s A123 service is crucial for maintaining vehicle performance, extending engine life, and preventing costly repairs down the road.

When Should a Honda A123 Service Be Done?

The Honda A123 service reminder typically appears around 30,000 to 45,000 miles, depending on driving conditions. It follows Honda’s maintenance minder system, ensuring you receive service at the right intervals.

If you frequently drive in harsh conditions—such as extreme temperatures, stop-and-go traffic, or dusty environments—you may need this service sooner. Always refer to your owner’s manual for the best maintenance schedule for your specific Honda model.
