Schematic for ET Jumper Harness
A jumper harness can be created to check fault codes with the ET Tool (2013B v1.0 and up) on certain CARM suspensions. Any suspension built after April 23, 2013 and/or with a serial number later than 19041346104 will be compatible with the ET Tool. The jumper consists of four wires, two connectors, and a resistor. See schematic below

Connect CAT ET and start connection to the ECM.
You will see the " Attempting to Connect" window open. Click "Stop Connect".
Select WINFLASH. CAT ET will search ATA, CDL then for the J1939 data link.
Now, power up the seat suspension.
The screen will open like you are going to flash the ECM. Now, go to the top left and connect to CAT ET. Wait, CAT ET will hook up!ET Fault Codes
Note: Using ET Tool (2013B v1.0 and up) and jumper described above
