Ok guys !



Well I went and had a B&D torque lock installed and that was two weeks ago. Today I had codes show up ,I am looking for some help form those who can help out.



This is what showed up

0622

0123

1693

1694

I looked them up and don't fully understand what they all mean so I am open for any explinations on this.





Thanks and looking forward to the input.

Jeff,



Did you ever find out what the codes mean. I just got the P0622 and P1765 tonight, after a complete trans rebuild. 3 day weekend and I get codes. 8 (



Any ideas?

Anyone?? My code reader will clear the p1765 but not the p0622 which is in the pcm. Anyone know how to clear that code and what is needed to fix the problem?



Is the truck drivable with this code?

Well, I think we found the fix for my truck setting the P0622 code. During the install of the ATS Trans Commander the wire for the aux power for the transmission relay was hooked up. After a few calls to the trans installer and ATS it was decided that this wire does not need to be connected for the 47re but does for the 48re. This morning we disconnected the aux power, disconnected the batteries to clear the codes in the pcu, reconnected the batteries after about 20 min with the key in the 'on' position. Turned the key off, reconnected the batteries, checked for codes, P0622 gone, started the truck, turned the truck off, checked for codes, P0622 still gone. CEL light now goes out after starting the truck. Code is still gone. Have started the truck over ten times with out the CEL staying on.



So, it appears that if you have an aftermarket way of locking up your tc, check to see if you have aux power going to the trans relay, its under the hood in the fuse box. I could hear mine switching with the key 'on' but not started. By removing this from my truck, I eleminated the P0622 problem.



Time will tell if it is a permenant fix.

Just in case someone still needs them-



P0622 - Generator Field Not Switching Properly - An open or shorted condition detected in the generator field control circuit. (Illuminates Generator lamp)



P0123 - Accelerator Position Sensor (APPS) Signal Voltage Too High - APPS voltage input above the maximum acceptable voltage.



P1693 - DTC detected in PCM/ECM - Companion DTC set in both ECM and PCM



P1694 - No CCD messages received from ECM



P1763 - Governor Pressure Sensor Volts Too High - Voltage greater than 4. 89 volts



P1765 - Trans 12 Volt Supply Relay Control Circuit - Current state of solenoid output port is different than expected.
