Case IH 706-02 - ACM – ACM: Configurable switch 6 circuit fault

The controller is detecting a voltage or resistance that is out of the expected range on the circuit assigned to Configurable switch 6, which usually points to an open circuit, a short to ground, a short to power, or a failed switch mechanism.

1. 1

   Verify Module Communication: Ensure the ACM is communicating properly with the network (related codes like 1012 or 1013 indicate a total loss of communication with the ACM)

2. 2

   Inspect the Switch: Identify which physical switch on the armrest is mapped as Configurable switch 6

3. 3

   Circuit Testing: Test the wiring harness between the switch and the ACM for continuity, shorts to ground, or shorts to power

1. 1

   Disconnect battery

   Disconnect battery power.

2. 2

   Disassemble console

   Disassemble the armrest console to access the ACM and switch wiring.

3. 3

   Repair or replace

   Replace the faulty switch or repair the damaged section of the wiring harness.

4. 4

   Reassemble and recalibrate

   Reassemble the console, restore power, and use the Electronic Service Tool (EST) to clear the fault code and recalibrate the armrest controls if necessary.
