USA. J1587 is the SAE-standard data bus that transports engine and sensor data around the chassis, including to most of the dash gauges. I suspect a code of "J1587" means the video display has lost contact with the data bus and doesn't know what is going on. Otherwise, it would display a more specific fault code.STEP 1.Check for Active or Inactive fault code status. Retrieve Active fault codes and FMIs with ServiceRanger using the 9-Way Diagnostic Connector. If Fault Code 36 is Active, concern is either the ECU or the Data Link from Engine ECU to J1939 Data Link Backbone. Refer to OEM for repair procedure. If Fault Code 36 is Inactive, test is complete.The ECM detects an open or short circuit condition in the J1939 Data link harness. Action Taken When the Fault Code is Active: • The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. • The ECM will use a default state as an input for the multiplexed device. Conditions for Clearing the Fault Code:Before I get into actual troubleshooting you will need to understand how to calculate the resistance in the J1939 harness. Here is the simplest formula and you will need your calculator. Product over sum R1xR2 R1+R2 120x120 = 14400 120+120 = 240 14400/240 = 60 ohms I see all the time inactive codes in the ABS for J1939 time outs on … between the battery ground terminal and the diagnostic connector pin D (J1939- 500k).
