AE Results and now Questions

[YoungMT Hick]

Ok so I got the AE tool and did some test on the truck and also got some codes. Test done with coolant at 141 F.

BUZZ Test - How many buzzes should you hear? It says you should hear all of them, then each injector 1-8. I heard three.

ICP was aroung 580 ish on idle at 750 rpm.

Ran a power balance and didnt really see much. every now and then seemed like I had a low spot right at #1 injector. less than 25 rpm deviation.

Coolant and oil temp were 165/160

All the codes I got

KOEO TEST U0306 Software incompaptible with FICM
DTC U1900 Can Communication Bus Fault
B2373 #1 LED circuit short to battery
C1710 Right Rear Center Sensor Fault
C1709 Right Rear Center Sensor Failure
B1359 Ignition Run/ACC ciruit Failure
B1483 Brake pedal input circuit failure
P1876 Transfer case 2-wheel drive soleniod circuit failure
B1352 Ignition Key-in Circuit failure
B1360 Igniton Run/Acc Circuit open
Anyone know what these codes could be or how to fix?

I've had the P1876 Transfer Case 2-Wheel Drive code for 2 years now. Haven't been able to figure out what it is but have felt no ill effects from it.

Just a question on the two ignition codes: Have you done the "dinger mod"? It's possible maybe that having pulled the ground wire your truck is considering that an error maybe?
