NOTE: Always make sure that you have the latest Honda Diagnostic System (HDS) software.
1. Connect the Honda HDS to the data link connector (DLC) Initial Inspection and Diagnostic Overview.
2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
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 Testing and Inspection.
4. Go to PGM-FI, and check for DTCs Initial Inspection and Diagnostic Overview.
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.
