SHAFT AS-OIL PUMP 6I1345 - Caterpillar

This test is for the communications link from the Caterpillar Electronic Technician (Cat ET) to the Power Train Control Processor (PCP) on the J1939 data link.
VERIFY THE VERSION OF Caterpillar Electronic Technician (Cat ET).
Ensure that the Cat ET version is ET2005A-01 or higher. Note: Always update Cat ET to the latest released version.
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.
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.
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.
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.
Determine the communication status between Cat ET and the PCP.
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.

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 12Expected 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.
