CID 0890 FMI 09 Telemetry Data Link Abnormal Update - Test

Usage:

793B 1HL
This diagnostic code is recorded when data link communication with the VIMS electronic control module has been broken for more than 5 seconds.

  1. VERIFY THAT THE BROADCAST SYSTEM IS FUNCTIONING CORRECTLY.

    1. Verify that the broadcast system (transmitter) is operating correctly.

      Expected Results:The broadcast system (transmitter) is operating correctly.

      Result:

      • YES - The broadcast system (transmitter) is operating correctly. Proceed to step 1b.

      • NO The broadcast system (transmitter) is NOT operating correctly. Repair the broadcast system. STOP.

    2. CHECK FOR AN OPEN IN THE MACHINE HARNESS

    3. Turn the key start switch and the disconnect switch to the OFF position.

    4. Disconnect connector J2 from the VIMS electronic control module.

    5. Disconnect the RS-232 broadcast port from the broadcast system.

    6. Measure the resistance of the circuits that are listed below:

      • Measure the resistance between contact 2 (wire E972-BU(Blue)) of the RS-232 broadcast port and contact J2-66 (wire E972-BU(Blue)) of the VIMS electronic control module.

      • Measure the resistance between contact 3 (wire 876-OR(Orange)) of the RS-232 broadcast port and contact J2-33 (wire 86-OR(Orange)) of the VIMS electronic control module.

      • Measure the resistance between contact 4 (wire 875-BU(Blue)) of the RS-232 broadcast port and contact J2-32 (wire 875-BU(Blue)) of the VIMS electronic control module.

      Expected Results: All the measurements are less than 5.0 ohms.

      Result:

      OK- All the measurements are less than 5.0 ohms. Proceed to step 2.

      NOT OK - All the measurements are greater than 5000 ohms. The machine harness has failed. Repair the machine harness or replace the machine harness. STOP.

  2. CHECK THE MACHINE HARNESS FOR A SHORT TO GROUND.

    1. The machine harness remains disconnected from the VIMS electronic control module and the broadcast system.

    2. Measure the resistance of the circuits that are listed below:

      • Measure the resistance between contact 2 (wire E972-BU(Blue)) of the RS-232 broadcast port and frame ground.

      • Measure the resistance between contact 3 (wire 876-OR(Orange)) of the RS-232 broadcast port and frame ground.

      • Measure the resistance between contact 4 (wire 875-BU(Blue)) of the RS-232 broadcast port and frame ground.

      Expected Results: All the measurements are greater than 5000 ohms.

      Result:

      • OK - All the measurements are greater than 5000 ohms. The machine harness is correct. The VIMS electronic control module has failed. It is unlikely that the VIMS electronic control module has failed. Exit this procedure and perform this procedure again. If the failure is not found, replace the VIMS electronic control module. Refer to the Testing and Adjusting, "Module-Replace" section.

      • NOT OK - All the measurements are less than 5000 ohms. The machine harness has failed. Repair the machine harness or replace the machine harness. STOP.
