NorE: The items m arked * 1, *2, +3, *4 and +5 on above chan are described as folows:*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper additives.*2: Always use Genuine Honda premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.+3: Use Genuine Honda cVTfluid only usingotherfluid can affect tra nsmission operation and may reduce transmission life.*4: Always use Genuine Honda DoT3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and dec.ease the lifeof the svstem.*5: Always use Genuine Honda Power steering Fluid. using any other type of power steering fluid or automatrc transmissionfluid can cause increased wear and poor steering in cold weather.

How To Begin Troubleshooting
When the Malfunction Indicator Lamp (MlL) has been reported on, or there is a driveability problem, use the appropr'-
ate orocedure below to diagnose and repair the problem'
A. When the MIL has come on:
,1. connect the Honda PGM Tester or an oBD ll scan tool to the 16P Data Link connector (DLC) located near the left
kick panel.
2. Turn the ignition switch ON (ll)
3. Check the DTC and note it. Also check and note
the freeze trame data
Refer to the Diagnostic Trouble Code Chart and
begin troubleshooting.
