1. 1

   Check the continuity of the two CAN network wires that link the Autotronic 4 to the DCC2 (Instrument Panel)

2. 2

   Verify battery voltage and ensure battery terminals are securely fastened and not contaminated, as low voltage can cause CAN modules to drop offline

3. 3

   Inspect the wiring harness for rub points, open circuits, or shorts to ground, particularly under the armrest and cab routing areas

4. 4

   Check for hardware program errors in the DCC2 or the Autotronic 4 using a dealer diagnostic tool

1. 1

   Disconnect power

   Disconnect the battery to prevent electrical spikes during the repair.

2. 2

   Inspect connectors

   Locate the connectors at the back of the Instrument Panel (Dash) and the Autotronic 4 controller. Unplug them and inspect the pins for corrosion, moisture, or pushed-out pins.

3. 3

   Repair wiring

   If the continuity test reveals a break or short in the CAN High or CAN Low wires, repair or replace the damaged section of the CAN bus wiring harness.

4. 4

   Reprogram modules

   If the wiring is completely intact and the connectors are clean, the fault is likely a hardware or software failure. Attempt to have a dealer re-flash/reprogram the DCC2 and Autotronic 4.

5. 5

   Replace faulty module

   If reprogramming fails, replace the faulty Instrument Panel or Autotronic 4 controller.

6. 6

   Clear codes

   Reconnect the battery, turn the ignition on, and use a diagnostic tool to clear the D150 code and verify that CAN communication is restored.
