5130, 5130B and 5230 Excavators, 784B, 785B, 785C, 789B, 789C, 793B and 793C Off-Highway Truck/Tractors and 992G, 994 and 994D Wheel Loaders Vital Information Management System (VIMS) Caterpillar

1. CHECK THE LAMP.

   1. Disconnect wire 411-PK(Pink) from the action lamp socket.

      Expected Result: The diagnostic code changed to CID 0324 FMI 05.

      Results:

      • OK - The diagnostic code changed to CID 0324 FMI 05. The lamp or the lamp socket has failed. Replace the action lamp. For the purposes of this procedure, the correct resistance for a lamp is greater than 10 ohms. STOP.

      • NOT OK - The CID 0324 FMI 06 is still active. The action lamp is not causing the diagnostic code. Proceed to 2.

2. CHECK THE HARNESS.

   1. Turn the disconnect switch to the OFF position.

   2. Wire 411-PK(Pink) remains disconnected from the action lamp.

   3. Disconnect the machine harness from the VIMS main module.

   4. At the machine harness connector for the VIMS module, measure the resistance between contact 20 (wire 411-PK(Pink)) and frame ground.

      Expected Result: The resistance is greater than 5000 ohms.

      Results:

      • OK - The resistance is greater than 5000 ohms. The harness resistance is correct. Proceed to 3.

      • NOT OK - The resistance is less than 5000 ohms. The harness has failed. Repair the machine harness or replace the machine harness. STOP.

3. CHECK THE MODULE.

   1. Remove contact 20 (wire 411-PK(Pink)) from the machine harness connector for the VIMS main module.

   2. Reconnect the harness connector to the VIMS main module.

   3. Turn the disconnect switch and the key start switches to the ON position.

      Expected Result: The diagnostic code CID 0324 FMI 06 is still active.

      Results:

      • OK - The diagnostic code CID 0324 FMI 06 diagnostic code is still active. The VIMS main module has failed. Replace the VIMS main module. Refer to the Testing and Adjusting, "Module - Replace". STOP.

      • NOT OK - The diagnostic code is NOT active. The VIMS module is not causing the diagnostic code. The diagnostic code is intermittent. The probable cause is a poor electrical connection at the harness connectors or a damaged harness. Check the harness for damage. If necessary, clean the harness connectors. STOP.

Note: The following procedure applies to machines that are equipped with LED indicators in place of lamps.

Illustration 1	g00730058

This diagnostic code is recorded when the VIMS module reads the current of the action lamp circuit as above normal. The circuit is shorted to ground. The action lamp will not illuminate when this diagnostic code is active.

1. CHECK THE ACTION LAMP.

   1. At the action lamp, disconnect the wire 411-PK(Pink) from the action lamp circuit.

      Expected Result: The diagnostic code CID 0324 FMI 06 is still active.

      Results:

      • OK - The diagnostic code CID 0324 FMI 06 is still active. The action lamp is NOT ON. The harness circuit 411-PK(Pink) is not causing the diagnostic code. Proceed to 2.

      • NOT OK - The diagnostic code CID 0324 FMI 06 is is no longer active. Replace the action lamp. STOP.

2. CHECK THE HARNESS

   1. Turn the disconnect switch to the OFF position.

   2. The wire 411-PK(Pink) remains disconnected from the action lamp circuit.

   3. Disconnect the machine harness from the VIMS module.

   4. At the machine harness connector for the VIMS main module measure the resistance from contact 20(wire 411-PK(Pink)) to frame ground.

      Expected Result: The resistance is greater than 5000 ohms.

      Results:

      • OK - The resistance is greater than 5000 ohms. The harness is correct. Proceed to 3.

      • NOT OK - The resistance is less than 5000 ohms. The harness has failed. Repair the machine harness or replace the machine harness. STOP.

3. CHECK THE POWER TRAIN ECM

   1. Remove contact 20 (wire 411-PK(Pink)) from the machine harness at the VIMS main module.

   2. Reconnect the harness connector to the VIMS main module.

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

   4. Check to see if the diagnostic code is still active.

      Expected Result: The CID 0324 FMI 06 is still active.

      Results:

      • OK - CID 0324 FMI 06 is still active. The action lamp is ON. The VIMS main module has failed. Replace the main module. Refer to the Testing and Adjusting, "Module - Replace". STOP.

      • NOT OK - The CID 0324 FMI 06 is NOT active. The VIMS main module is not causing the diagnostic code. The diagnostic code is intermittent. The probable cause is a poor electrical connection at the harness connectors or a damaged harness. Check the harness for damage and clean the harness connectors as required. STOP.
