Thread: Td5 revs at will.

Thats great, gives me something go on. BTW HFD.

RAVE 18-1-27

The clutch switch is located at the rear of the engine compartment on the RH side. The switch is operated by hydraulic
pressure when the clutch pedal is pressed. The ECM uses the signal from the clutch switch for the following functions:
l To cancel cruise control if operating.
l To provide surge damping during gear change.
Surge damping stops engine speed rising dramatically (engine flaring) during gear change. Surge damping assists
driveability as follows:
l Smoother gear change.
l Greater exhaust gas emission control.
l Improved fuel consumption.
Input/Output
The clutch switch receives battery voltage from the BCU. With the clutch pedal in the rest position the switch is closed,
allowing battery voltage to pin 35 of the ECM connector C0658. When the clutch pedal is pressed the switch contacts
open, interrupting the power supply to the ECM. The ECM receives 0 Volts.
The clutch switch can fail in the following ways:
l Switch open circuit.
l Short circuit to vehicle supply.
l Short circuit to earth.
In the event of a clutch switch failure the ECM will react as follows:
l Surge damping will be inactive.
l Cruise control will be inactive.

Thats awesome, thanks Kev.
