The service code b124 on a 2006 Honda Accord means that you have turned off the vehicle stability assist system. If it comes on with the VSA indicator light it suggests that there is a problem with the system.
You would need to look it up in the owner manual.
Excel offers many more options than you would find on a calculator or paper & pencil. Consider this question: Why would you drive a car or fly in an airplane when you could walk or take a boat? If you only need to visit your friend next door, you most likely would walk (not take an airplane). If you just want to add three numbers to find the sum, you probably would use a calculator or paper & pencil.The choice of tool to use is yours, but consider that two primary reasons for using Excel relate to speed and capability (the same as your choice of transport from one location to another).EXAMPLES OF SPEED (possible to use calculator, but Excel is better option):You have a column of 123 numbers in MS Word. You want to find the SUM of these numbers. You highlight the column of numbers in Word and paste them into Excel (assume you pasted in column B, rows 1-123). You then go to the first blank cell at the bottom of the list of numbers (cell B124) and enter =SUM(B1:B123).You have two dates (3/14/2008 and 1/21/2010) and want to find the number of days between the dates. Enter your first date in cell A1 and your second date in cell B1. In cell C1 enter =B1-A1. Another option would be to use a single entry of ="1/21/2010" - "3/14/2008"Find the SUM of twenty columns of numbers, then find the average (MEAN) value of the totals.EXAMPLES OF CAPABILITY (probably could not use calculator):Link to data from an external source and draw a graph in real time.Save twenty columns of numbers, so you can make changes to three of the numbers in the entire list and automatically update the relevant totals.Automatically extract stock prices from an online database and track prices over time. Highlight each cell where the price was above or below a target price.
