NOTES
This code is logged to real time to protect the transmission in case a loss of power to the ECU (Power Inter-
(1)
ruption, code 35 00) occurs.
The ECU hardware or software must be changed so that they are compatible.
(2)
Additional codes could be logged for other shifts where X indicates range shifted from and Y indicates range
(3)
shifted to.
The COP reset will clear the active inhibit.
(4)
The factory calibration must be rewritten to the ECU, or a different factory calibration is required to match
(5)
the software in the ECU.
