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.

NOTE:  Use fender covers to avoid damaging painted surfaces.
 To avoid damaging the wire and terminals, unplug the wiring connectors carefully while holding the
connector portion.
 Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.
1. Secure the hood in the wide open position (support rod in the lower hole).
2. Relieve the fuel pressure (see page 11-322).
3. Do the battery removal procedure (see page 22-69).
4. Disconnect the vacuum hose and the breather pipe, then remove the intake air duct (see step 2 on page
9-3).
5. Remove the air cleaner assembly (see page 11-345).
6. Remove the under-cowl panel (see step 4 on page 20-164). 7. Disconnect the connector (A), and remove the
harness clamps (B), then remove the pipe (C).
8. Disconnect the battery cables (A) from the under- hood fuse/relay box.
9. Remove the harness clamp (B). (cont’d)

65. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation three times, then check
for fuel leakage at any point in the fuel line.
66. Refill the engine with engine oil (see step 4 on page 8-10).
