Multifunctional automatic transmission switch (Renault Symbol 2)

The multi-function switch informs the ECU of the position of the gear selector lever, preventing the starter from starting when gears are engaged and controlling the reversing lights. The switch is mounted on top of the gearbox housing under the air intake duct.

Tightening torques:

• Switch mounting bolt - 10 Nm
• Lever mounting nut - 10 Nm

Removal

• disconnect the negative battery cable;
• set the selector lever to position "D";
• remove the air intake duct;

• remove the engine wiring harness mounting bracket 1;

• disconnect the selector cable joint from the multifunction switch lever;
