What is Honda A12 Service?
Known for its advanced features and cutting-edge technology, Honda has a reputation as one of the world’s leading automakers. An electronic maintenance reminder system on Honda vehicles lets owners know when their vehicles need maintenance after a certain distance has been covered.
When engine oil life gets low, the system slowly monitors it and displays it on the dashboard. The dashboard will then flash a service due message when service is due.
The Honda A12 maintenance reminder system will also alert you when a Honda A12 service is required after monitoring different vehicle conditions, including mileage and time intervals, and measuring and recording sensor readings. It is recommended, however, that you watch this video in order to gain a deeper understanding of Maintenance Minder.
What does the Honda A12 maintenance code mean?
There is usually at least one subcode and one main code for every Honda service code. Each of these digits represents a specific service task, which is described below.
- A: Main codes always denote the primary function of the service, which in this case is the replacement of engine oil.
- 1: This sun code denotes that you should inspect your tires, rotate them, adjust the pressure, and check their condition.
- 2: Replace dust and pollen filters as well as inspect air cleaner elements and drive belts.
Important Note:
while the A12 code generally consists of the above tasks, it is always recommended to inspect other components like the injection system, coolant levels top-up, battery health, and sensors checking.
Honda A12 Service Checklist: What’s Included?
The following is a list of commonly included A12 services.
- Engine oil changing
- Tyre inspection
- Air cleaner element inspection
- Drive belt replacement
- Dust and pollen filter changing
Engine Oil Changing
A good engine oil plays a crucial role in boosting efficiency and optimising performance. Oil that is too old or of low grade can damage engine conditions, causing the engine to fail. It’s for this reason that oil changes are mandatory with every scheduled maintenance appointment.
Clean the oil tank thoroughly after draining the old oil you can no longer use to change the engine oil. The old contaminated oil filter needs to be replaced with a new high-quality filter to prevent further contamination. Replace the oil filter after changing the oil, and then fill the engine with fresh Honda-approved oil.
Make sure to always use high-quality oils and filters, no matter how expensive they are, since they will eventually improve engine performance.
Tyre Inspection
In addition to performing the A12 service, a tyre inspection will be conducted. The process typically involves moving each tyre separately so that wear and damage can be assessed. During tire rotation, it is possible to tell if there is any damage or if any repairs need to be made.
Second, check the pressure in your tires and adjust them if necessary. The lousy road conditions and brutal weather often cause our vehicle’s tyre pressure to decrease while we’re traveling. Keeping the tire pressure at the right level is important to ensure that all tires are functioning at their best.
Air Cleaner Element Inspection
A well-functioning engine depends on clean air intake to ensure efficient performance. Air cleaners filter out dust and debris from air entering the engine.
To determine if the air cleaner element needs to be replaced, an inspection of it is mandatory during the service on the A12 Honda Civic. Replaced with a new one if necessary, the old air cleaner will be replaced by the mechanic.
Drive Belt Replacement
The drive belt is made up of rubber, and its function is to transfer power from the engine to various components like a generator, water pump, air conditioner compressor, and power steering pump.
Visual inspection will be performed by the mechanic to check for cracks, wear, and damage. As soon as damage to the drive belt is detected, he will advise that you replace the belt and use a new one.
Dust And Pollen Filter Changing
Last but not least, the cabin air filter is inspected to conclude the A12 service. In addition to protecting the driver and passengers from dust and pollen, allergy triggers, smog, and harmful particles, it also acts as a shield between the vehicle and the outside world. By doing so, you will be able to maintain a comfortable indoor environment and keep the air clean.
In order to ensure that the cabin air filter is working properly, the mechanic will inspect it. Replacement is necessary if the filter is clogged or dirty.
