•
Unplug the TCM before electrical welding service in any part of the vehicle.
•
The connectors P1, J1, P1A, J1A, P1B e J1B require maximum care when plugging or unplugging them from TCM and
harness.
•
The range and deep valves bobbin have a resistance between 213 and 235 Ohms @ 20ºC
•
The breakout box warning lamp has the same behavior of the cabin warning lamp (it lights for 2 seconds when the key
is "on" position and flash when the transmission is in downshift protection).
