1.3 Clutch Pedal Calibration Switch
A clutch pedal calibration switch has been introduced to improve shift quality during gear changes. When the throttle is
closed the powertrain control module (PCM) checks whether the clutch is pressed or released. Based on this, the PCM
then controls ignition timing to reduce engine flare or drive train clunk.
Refer to Figure 6C1 – 12 for the following description.
The EFI relay is energised when the ignition switch is in the ON position thus supplying power to the clutch pedal
calibration switch. When the clutch pedal is released, the clutch pedal calibration switch S42 is open and will not allow
battery voltage to flow through to the PCM A84 V6. When the clutch is pressed, the clutch pedal calibration switch is
closed allowing battery voltage to the PCM.

2.3 Clutch Pedal Calibration Switch
Figure 6C1 – 24
Introduction
A clutch pedal calibration switch has been introduced to improve shift quality during gear changes. When the throttle is
closed the PCM checks whether the clutch is depressed or released. Based on this the PCM then controls ignition timing
to reduce engine flare or drive-train clunk.
If the clutch pedal is depressed with the throttle closed, ignition-timing advance is reduced quickly. This reduces engine
flair. If the throttle is closed with the clutch pedal left engaged, ignition-timing advance is reduced slowly. This reduces
clunk and bump characteristics from the transmission.
The switch is arranged so that it is open circuit with the cl utch pedal released. When the clutch is pressed the plunger is
depressed and the switch is closed circuit.
If the clutch pedal calibration switch fails in an open circuit position the most obvious symptom would be engine flair on
gear changes.
If the clutch pedal calibration switch fails in the closed position engine r.p.m. will reduce more quickly than normal. Some
driveline clunk may be evident if the throttle is closed when driving. This effect will only be slight, and possibly more
noticeable in the lower gears.
Circuit Description
Once the EFI relay is energised, power is taken from fuse 33 and supplied to the clutch pedal ca libration switch. When
the clutch pedal is depressed, the switch is closed and a signal is sent to the PCM.
Test Description
The following numbers refer to step numbers in the following diagnostic chart.
1 Checks whether fuse F33 is serviceable and whether there is a short to ground in circuit 439.
2 Isolates whether the clutch pedal calibration switch is at fault.
3 Checks if there is battery power to the clutch pedal calibration switch S42. Isolates whether there is an open-circuit
in circuit 439.
4 Checks for battery voltage at the PCM with the clutch pedal calibration switch open. Isolates whether there is a
short-circuit to battery in circuit 48.
5 Checks for battery voltage at the PCM with the clutch pedal calibration switch closed. Isolates whether there is a
fault in circuit 48 or the PCM is at fault.
