Cruise Control (PCM) Input Test

Cruise Control (PCM) Input Test

NOTE: Always make sure that you have the latest HDS software.

1. Connect the Honda HDS to the DLC.

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 PCM. If it does not communicate, troubleshoot the DLC circuit PCM Power and Ground Circuit Troubleshooting.

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.

6. If the input tests prove OK, replace the PCM Service and Repair.

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.
