1. Move the auto-tensioner (A) using the belt tension release tool to relieve tension from the drive belt
(B), then remove the drive belt.
2. Install the new drive belt in the reverse order of removal. Belt tension release tool Snap-on YA9317 or equivalent,
commercially available
1. Turn the ignition switch to ON (II), and make sure the A/C switch is OFF, then turn the ignition switch
to LOCK (0).
2. Check the position of the auto-tensioner indicator’s pointer (A). Start the engine then check the position
again with the engine idling. If the position of the
indicator moves or fluctuates very much, replace
the auto-tensioner (see page 4-32).
3. Check for abnormal noise from the tensioner pulley. If you hear abnormal noise, replace the tensioner
pulley(seepage4-33).
4. Remove the drive belt (see page 4-31).
5. Move the auto-tensioner within its limit using the belt tension release tool in the direction shown.
Check that the tensioner moves smoothly and
without any abnormal noise. If the tensioner does
not move smoothly, or you hear abnormal noise,
replace the auto-tensioner (see page 4-32).

Cruise Control Input Test
NOTE: Always make sure that you have the latest Honda Diagnostic System (HDS) software before doing the input
tests.
1. Connect the HDS to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain control module (PCM). If it does not communicate, troubleshoot the DLC circuit (see page 11- 204).
4. Go to PGM-FI, and check for DTCs (see page 11-3).
5. Do the following tests while monitoring parameters in the PGM-FI DATA LIST with the HDS. NOTE: Intermittent failures are often caused by loose circuit connections. While monitoring cruise control inputs,
flex the circuit wires, and note if any of the test results change.
