Let me Google that for you:

It's the maintenance code for your timing belt service.

 

OP -

You don't mention mileage or year of your RL, but if you scroll to the bottom of this page, it will help you with what all of the maintenance items associated with the letters and numbers that pop up on you MID display.

 

It's a 2008 rly and the mechanic says it was changed at 65000 miles it now has 99000

And it's a 2008

Thanks for all your help,how much for timing belt service?

 

Since the timing belt was changed at 65,000 miles you do not need to change it at this time. Acura recommends the timing belt be replaced every 7 years or 105,000 miles.

My local Acura dealership quoted me a price of $1,372 to replace the timing belt and water pump. Dealership prices may vary slightly for this service. An independent repair shop may do it for around $600 - $700.

 

Thanks you guys are awesome
