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.

SRS components are located in this area. Review the
SRS component locations (see page 24-11), and
precautions and procedures (see page 24-13), before
doing repairs or service.
1. Remove the driver’s airbag (see page 24-188).
2. Remove the steering wheel trim.
3. Remove the cruise control combination switch. 4. Check for continuity between the terminals in each
cruise control combination switch position
accordingtothetable.
 If there is continuity, and it matches the table, but the cruise control combination switch failure
occurred on the cruise control input test, check
and repair the wire harness on the switch circuit.
 If there is no continuity in one or more positions, replace the cruise control combination switch.
