Code 17-06 Lost BTM Communication — Bluetooth module not communicating with control board

What does 17-06 mean?

The Bluetooth module fails to send periodic status messages to the PCM (control board) for 2 consecutive minutes after unit power-up. This means the service app will not be able to connect to the unit. The fault clears when a single good message is received.

• Loose wire harness between PCM and Bluetooth module.
• Damaged wire harness.
• Faulty Bluetooth module.
• No power to the Bluetooth module.

Click steps to track your progress.

1. 1

   Inspect the wire harness between the PCM and the Bluetooth module.

2. 2

   Ensure both ends of the harness are fully seated on the board header.

3. 3

   Check for any visible wire damage on the harness and repair if necessary.

4. 4

   If there is no green or red LED on the Bluetooth module, check for 18-30 VAC between pins 1 and 3 at the Bluetooth module connector end of the harness (technician step).

5. 5

   If voltage is present and the code is active, replace the Bluetooth module.
