UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.You are correct, if the main relay was bad the engine would not start and run. In order to determine the cause of the light coming on the computer system needs to be scanned to see what the fault code and or codes are that should be setting when the light comes on. Can you get me the fault codes and if so we can work from there to try and get this issue resolved.
Most shops should be able to access the computer system but if your can not then unfortunately yes, it will have to be done by your dealer.
If the are using a Honda compatible scan tool then they can access any fault codes. If the do not have a Honda Compatible scan tool then the dealer is going to need to do the scan for you.
