    CAT 259D - No Crank E459-2 Code

    Problem Solved. btw, the harness that goes into the ECU is a molex from what i learned...so a little different than the Deutsch. I feel slightly dumb...because it ended up being a fuse. o_O When i tested all the positives and grounds in the J1 Connector, the grounds were all good but there...

    CAT 259D - No Crank E459-2 Code

    I visually inspected connector 23 and also backprobed it and it was good. I did run power through the connector from one end to the other and it was okay. Arc suppressor changed swapped with the other one and no change. Good idea Nige, I will test all those powers and grounds. It may be a...

    CAT 259D - No Crank E459-2 Code

    I was able to check the wires from the ECU harness pin 3 and 23 all the way up to the end of the line at the relay and the arc suppressor...alss checked in between at CONN 5. I checked continuity and it was there....so i ran 12volts through the wire and checked with multi meter and also had...

    CAT 259D - No Crank E459-2 Code

    Update: Not fixed... Relay was actually good. I put in the new one and it didn't solve the problem...fully bench tested the old one and it worked. I can get power to the ECM by grounding wire c903-59 to a good ground. The relay will click and it will take away the e459-2 with crank/no...

    CAT 259D - No Crank E459-2 Code

    Update: no power to ECM. There is a relay behind the cab. When power is keyed on, it is supposed to send power to the ECM. There are 2 fuses on the relay, those both tested good. The relay is not sending keyed power to ECM. I am glad i found the other wires, those would have been a problem...

    CAT 259D - No Crank E459-2 Code

    Thank you Nige. I started inspecting wires and looking for any possible problems. Behind the cab on the (8) Control GP Machine ECM i found some rubbed wires. They were making contact with a hydraulic hose and were rubbed through. The wires have been identified as: CAN HI-F711-C205 YL- 18 CAN...

    CAT 259D - No Crank E459-2 Code

    I just had the e459-2 code pop up on my 2015 299D serial # CAT0299DJGTC01723 I hooked up cat ET and Cat ET does not find the ECM. Does anyone have the Electrical Schematic they can send me? I will start checking all the known failures in all the e459-2 threads. Thanks for the help!!

    Cat 272d2 XHP preheat issue

    Thanks for checking. I will get a diode and see if that solution works. Hopefully that will trick the ECU! I will report back to share the results after.

    Cat 272d2 XHP preheat issue

    I just had a 299d2 with the same problem. Had error code 523544-4 (engine start aid voltage below normal). Tested all electrical in line to the air inlet heater. Found that the ECU was only sending around 9.3 volts to the solenoid relay and it was not enough to activate it to send power to...

    2021 Cat 289D3 no power to glow plugs!?!?

    SOLVED: I wanted to give an update so if anyone else has this problem it may help. I had one glow plug that was bad, it was shorting out the fuse that feeds power to the relay that activates the glow plugs. I replaced the glow plug and everything is working. When I ohm checked the glow plugs...

    2021 Cat 289D3 no power to glow plugs!?!?

    Thanks so much guys! Nige, The schematic was extremely helpful and I traced it back to a blown fuse that feeds the relay to the glow plugs....thanks Deimos, that was the right spot you pointed out. I bought a new relay because it was only $9 and installed that along with a new fuse. As soon...

    2021 289D3 JX905845 Cold weather hit and it was struggling to start in cold. Started checking some things and there is no power to glow plugs. I recently got Cat ET to solve some other calibration problems on this machine....and so I and hooked it up...In ET, it shows that power to starting...
