of the red cable and the black cable between the electrical motor connector and the control
unit connector: if they are not OK, restore the cable harness; if they are OK, check that there
is not continuity on the circuit of the electrical motor and replace it.
•
If input current is excessive: check the driving half-pulley movement system mechanically
(excessive friction material).
•
If the signal is not valid: set the key to key ON and check the voltage value at PIN A8 and
B8 which should be approximately 3 V at both PINS; if there is voltage similar to battery
voltage or there is continuity with the ground in one of the two PINS, restore the cable har-
ness; otherwise, replace the transmission ECU.
