Cruise Control Input Test
WARNING: This page is about a different variant/trim than selected.
- Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on GENERAL TROUBLESHOOTING INFORMATION ).
- Turn the ignition switch to ON (II).
- Make sure the HDS communicates with the vehicle and the powertrain control module (PCM). If it doesn't communicate, go to DLC CIRCUIT TROUBLESHOOTING .
- Go to PGM-FI, and check for DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).
- 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 their circuits, and note if any of the test results change.TEST CONDITION REFERENCE TABLE
Signal to be tested Test condition Parameter: Desired result Possible cause if result is not obtained Brake pedal position switch signal Brake pedal pressed, then released CRUISE BRAKE SW should indicate OFF when the brake pedal is pressed and ON when the brake pedal is released. - Faulty brake pedal position switch

- An open in the wire between the PCM and the brake pedal position switch
- A wire shorted to ground between the PCM and the brake pedal position switch
Transmission range switch signal Shift lever in D SHIFT/CLUTCH SW should indicate ON in P, R, N, and Land OFF in D and S. - Faulty transmission range switch
- An open in the wire between the PCM and the transmission range switch
- A wire shorted to ground between the PCM and the transmission range switch
Cruise control main switch signal Cruise control main switch ON and OFF CRUISE MASTER (MAIN) SW should indicate ON when the cruise control main switch is turned on and OFF when the cruise control main switch is turned off. - Faulty cruise control main switch
- An open in the wire between the gauge control module (TACH) and the cruise control main switch
- A wire shorted to ground between the gauge control module (TACH) and the cruise control main switch
Set switch signal Set/decel switch pressed and released CRUISE SET SW should indicate ON when the set/decel switch is pressed and OFF when the set/decel switch is released. - Faulty cruise control combination switch
- An open in the wire between the gauge control module (TACH) and the cruise control combination switch
- A wire shorted to ground between the gauge control module (TACH) and the cruise control combination switch
Resume switch signal Resume/accel switch pressed and released CRUISE RESUME SW should indicate ON when the resume/accel switch is pressed and OFF when the resume/ accel switch is released. - Faulty cruise control combination switch
- An open in the wire between the gauge control module (TACH) and the cruise control combination switch
- A wire shorted to ground between the gauge control module (TACH) and the cruise control combination switch
Cancel switch signal Cancel switch pressed and released CRUISE CANCEL SW should indicate ON when the cancel switch is pressed and OFF when the cancel switch is released. Faulty cruise control combination switch Cruise control indicator signal Start the engine, turn the cruise control main switch on, and drive the vehicle above 25 mph (40 km/h). Set and cancel the cruise control. CRUISE INDICATOR should indicate ON when the cruise control is set and OFF when the cruise control is canceled. Faulty gauge control module (TACH)
