Marine Multi-Station Control System Caterpillar

1. VERIFY THE VERSION OF Caterpillar Electronic Technician (Cat ET).

   1. Ensure that the Cat ET version is ET2005A-01 or higher.

      Note: Always update Cat ET to the latest released version.

   2. Ensure that the 171-4401 Communication Adapter II (or newer) is being used.

      Note: The 7X-1700 Communication Adapter Gp does not support J1939 data link communications.

   3. Ensure that the firmware for the Communications Adapter II is from the latest Cat ET software release. Check the latest CD for Cat ET firmware updates.

   4. Ensure that the cables that are being used are 196-0055 Adapter Cable As and the 207-6845 Data Link Cable As.

      Note: The Communications Adapter II will not function properly with the 139-4166 Data Link Cable As.

   5. Connect Cat ET to the J1939 data link. Try to find a second component such as an MPD on the data link. If only an engine ECM can be found go to File/Switch Data Link.

      Expected Result: The Cat ET version is ET2005A-01 or higher. The cables are correct.

      Results:

      OK - The Cat ET version is ET2005A-01 or higher. The cables are correct. Go to Test Step 4.

      NOT OK - The Cat ET version IS NOT ET2005A-01 or higher or the cables ARE NOT correct.

      Repair: Obtain the correct hardware and software. Install a version of Cat ET that is ET2005A-01 or higher.

      STOP.

2. Determine the communication status between Cat ET and the PCP.

3. Connect using WinFlash. Can the PCP or the MPD displays be seen?

   Expected Result: No-MPD or PCP displays cannot be seen.

   No-The PCP display cannot be seen, but the MPD display can be seen: Check wiring to PCP. Check the battery. Go to Next Step.

   Yes-Reconnect with Cat ET.

4. VERIFY THE POWER SUPPLY WIRING.

   1. Turn the keyswitch ON.

   2. Measure the voltage between the following pins on the MJB to PCP cable:

      • Pin 1 to pin 7

      • Pin 8 to pin 7

      • Pin 9 to pin 7

      • Pin 3 to pin 12

      • Pin 10 to pin 12

      • Pin 11 to pin 12

      Expected Result: The voltage is between 9 VDC and 32 VDC for all of the pin combinations.

      Results:

      OK - The voltage is between 9 VDC and 32 VDC for all of the pin combinations. Go to Test Step 5.

      NOT OK - The voltage IS NOT between 9 VDC and 32 VDC for all of the pin combinations.

      Repair: Replace the cable or repair the cable. Exit this procedure. Perform this procedure again.

      STOP.

      Note: Pay special attention to the orientation of the power connector when plugging the power cable into the PCP. The power connector has keys (1) as shown in illustration 1. The power cable can be inserted into the connector upside down. All of the inputs are protected from a direct short to the +battery circuit, but the PCP will not operate when the connector is inserted upside down.

5. VERIFY THE J1939 DATA LINK WIRING.

   Note: A data link error message will appear on the Marine Power Display (MPD) if there is a problem with the J1939 circuit.

   Screen for "CONTROL SYSTEM INFORMATION"

   1. If an error message does not appear on the MPD, ensure that the MSCS screens appear on the MPD.

      Note: The screen for "CONTROL SYSTEM INFORMATION" will appear only when the MPD recognizes communications with the PCP. If this screen is displayed, the PCP is active. The PCP appears to be working properly.

   2. Verify the J1939 wiring to the PCP. Remove the termination resistors from the data link. Measure the resistance between pin 1 and pin 2 on the PCP connector. Refer to illustration 4.

      Table 1

      Measure from Pin Number	Circuit Name	Measure to Pin Number	Circuit Name
      1	J1939 +	12	J1939 Shield
      2	J1939 -	12	J1939 Shield
      1	J1939 +	4	-Battery
      2	J1939 -	4	-Battery

   3. Continue to make measurements with the pin combinations that appear in table 1.

      Expected Result: The resistance for all of the measurements is greater than 20000 Ohms.

      Results:

      OK - The resistance for all of the measurements is greater than 20000 Ohms. Go to Test Step 6.

      NOT OK - The resistance for all of the measurements IS NOT greater than 20000 Ohms.

      Repair: Repair the cable or replace the cable. After the repair, recheck to ensure that the resistance is greater than 20000 Ohms.

      STOP.

6. MEASURE THE RESISTANCE OF THE MAJOR CONNECTING CABLES.

   1. Remove the termination resistors from the J1939 data link.

   2. At the end MPD that has a termination resistor, insert a jumper between pin 5 and pin 6 on the J1939 data link.

   3. At each node on the J1939 data link, measure the resistance between pin 7 and pin 8 on the MPD connector.

   4. Measure the resistance between pin 3 and pin 4 on the PCP connector.

   5. Measure the resistance between the J1939 + pin and the J1939 - pin on the ECM and on the ETP.

      Expected Result: The resistance for all of the measurements is less than 20 Ohms.

      Results:

      OK - The resistance for all of the measurements is less than 20 Ohms.

      STOP.

      NOT OK - The resistance for all of the measurements IS NOT less than 20 Ohms.

      Repair: Repair the cable or replace the cable. After the repair, recheck to ensure that the resistance is less than 20 Ohms.

      STOP.

Backup Panel will only Engage Gears with no Throttle

1. In the ECM engine configuration screen, change the number of synchronized engines from one to two.

Transmission will not Shift into Gear

Transmission will not shift into gear while using an active control station, but will shift into gear when using the backup control stations.

1. Verify that the System Voltage Select jumper is installed properly for the 24 VDC system and not installed for the 12 VDC system.
