Integrated Diagnostic System (IDS) Scan Tool Usage

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

If The IDS Scan Tool Does Not Communicate With The VCM

Check the VCM power; examine the connection to the vehicle.
- The VCM LED illumination prove-out confirms power and ground from the DLC are provided to the VCM.
- Recommended Practice: REFER to MODULE COMMUNICATIONS NETWORK , No Power to the Scan Tool, to diagnose no power to the VCM.
Check the scan tool connection to the VCM.
Follow scan tool instructions to retry.

If The IDS Scan Tool Does Not Communicate With The Vehicle

The IDS scan tool first attempts to communicate with the PCM. After establishing communication with the PCM, the scan tool then attempts to communicate with all other modules on the vehicle.

Verify the scan tool operation with a known good vehicle.
Verify the ignition is ON.
If an IDS session cannot be established with the vehicle (IDS may state "No communication can be established with the PCM"):
- Choose "NO" when the scan tool prompts to retry communication.
- Establish a session based on the PCM information (above).
Using the tool box menu, run the network test.
- Determine if all modules on the network are unresponsive or if only the PCM does not communicate.
- Recommended practice: REFER to Symptom Chart in MODULE COMMUNICATIONS NETWORK to diagnose the network outage or no response from the PCM.
