- Perform inspection and note results on tablet.
- Test drove and was able to duplicate the concern several times. Connected the scan tool and found several 10+ Uxxxx communication fault codes stored in several different modules. Removed the ECM, battery, battery ground connections, ABS module connections, all large main engine harness connections and checked for corrosion or damage. All connections are normal. Checked rear electrical body connections at the rear of the vehicle near the left rear tire area, normal. Removed and inspected the transmission control module connection on the transmission, normal. Relearned the yaw rate sensor, steering angle sensor and multi-axis sensor. Test drove for 2 days, 43 miles and no more warning indicators or fault codes stored. Suspect poor connection, fretting or module hard reset needed in one of the modules.
