Mounting procedure
TCU 1.2
Ref : C3140690010
Version : A1
To link a bracket base to a bracket extension, 2 bolts are needed, type M6, length 16mm, with 2
M6 washers (1 standard type and 1 Belleville type).
6. TCU 1.2 CONNECTION
After its connection onto TCU 1.2, cable must be fastened as close as possible of its TCU 1.2
starting point (end of connector base).
This cable fastening must be done on a hole of the bracket base to minimize the effect of
vibration onto the connector assembly, see picture below:
From the TCU 1.2 connector base to the fixation point on the bracket base, the cable curvature
diameter must be higher than 100 mm.
Verify that no tension stress is applied onto the harness between TCU 1.2 and the fixation
point onto the vehicle chassis, this check must be done after connection of the harness
connector onto the TCU 1.2 connector and after the fastening of the cable onto the bracket
base. Always avoid contact between cable and shape edge of the bracket.
The connector must be secured , means 2 harpoon shapes, each side of connector, must be
locked.
Nota Bene : Incorrect wiring should prevent the system to operate properly.
TCU 1.2 has to be connected to +12V or +24V through 5A fuse protection.
To power supply the TCU 1.2, it has to be connected on KL31 (battery negative) and KL15
(ignition).
