Update: I went back and tested continuity across the entire CCD Bus systems. I got a 27 ohm reading between the PCM and TCM, on the BUS+ BK/WH wire. Can you provide direction on how to trace this? My initial thought is to check the C100 connector, and then looking at splice location. Could...

Still trying to figure out why the CCD BUS voltage is low. It is reading .3v on pin 3 and .09 on pin 11. Replaced PCM, cleared codes, and runs good with no codes, but the voltage is still low on the CCD BUS. I've checked grounds. It appears the 2.5V originates at the gauge cluster for BUS. I...

Wolverine -I've been through every ground twice on this rig, over the last 2 weeks. I thought that was the issue as well.

Tim - Thank you for the guidance. Here is an update: Replaced the TCU. Cleared all codes. Ran it for an hour, now the TPS sensor codes popped up. Replaced TPS with oem TPS. Cleared codes. Runs good. No Codes, but the voltage on the bus is still low. I am going to replace the PCM. Any...

To clarify on the FSM - I meant a paid / legal version for download.

2001 XJ, 4.0L auto. This is my son’s XJ, daily driver to/from school 3 weeks ago replaced 2 top O2 sensors, NTK Brand . (hindsight should've done all 4 at once), not sure if this relevant. A week later CEL comes on - P1694, my son said gauges would go to zero and engine would briefly cut off...
