Acura A Service – What Do These Codes Mean?

When your Acura is ready for a bit of TLC, onboard computer will display a service code. The “A” in the code means that your vehicle needs and oil change and oil filter change. The numbers that follow letter A indicate additional maintenance items.

For example “1” stands for “rotate tires”, so if your Acura display A1 code, it means oil change and tire rotation. “A5” code means oil change and coolant flush and replacement.

Below is a list of the codes you might see at some point:

1 – check tire pressure, and rotate tires

2 – replace dust and pollen filters, and check the drive belt

3 – replace transfer fluid and transmission fluid, where applicable.

4 –  replace spark plugs, replace timing belt ( if applicable ), inspect valve clearance and water pump ( if we are replacing the timing belt, we recommend water pump replacement as well since the majority of the labor cost is already covered because of the timing belt replacement)

5 – coolant flush and replacement

6 – rear differential fluid replacement (where applicable)

Naturally, you don’t really have to know what these codes mean – at Adams Autoworx we will service your Acura following all of the manufacturer recommended inspections and tests, and we add a few of our own, just to make sure that your Acura will serve you reliably in the future.

So when your Acura displays one of the services codes, give us a call – we will be happy to explain what maintenance items and inspections are involved, and can confirm your appointment at the same time.
