Clutch Pedal Switch -F36-, Checking

Clutch Pedal Switch -F36-, Checking







Recommended special tools and equipment
- VAG1526A multimeter
- VAG 1527 B Voltage Tester
- VAG1594A connector test kit
- VAG1598/31 test box

NOTE: This signal helps prevent excessive RPM oscillations and tip-in shocks when clutch is disengaged and is required for the cruise control system.

Test requirement:
- Ignition switched off.

Check switch
- Remove driver-side storage compartment:







- Disconnect harness connector at Clutch Pedal Position (CPP) switch -1-.







- Connect multimeter between terminal 2 and 3 for resistance measurement.
- Specified value: approx. 0 Ohm
- Depress clutch pedal.
- Specified value: Infinity ohm (no continuity)

If specified value is not obtained:
- Replace Clutch Pedal Position (CPP) switch.

If specified values are obtained:

Checking voltage supply







- Connect e.g. V.A.G 1527 B voltage tester as follows:

Harness connector Terminal Measure to
3 Chassis Ground (GND)

- Switch ignition on.
- LED must light up.
- Switch ignition off.

If LED does not light up:
- Check wire connection for open circuit.
- Specified value: Wire resistance max 1.5 Ohms
- If necessary, repair wire connection.

If LED lights up:

Checking control wire
- Connect test box to wiring harness of Engine Control Module (ECM); ECM is not connected.







- Check the following wire connection for open circuit according to wiring diagram:

Harness connector Terminal Test box Socket
2 39

- Specified value: Wire resistance max 1.5 Ohms

- Check the wire for short circuit to B+ and to Ground (GND).
- Specified value: Infinity ohm (no continuity)
- If necessary, repair wire connection.

Final procedures
After repair work, the following work steps must be performed in the mentioned sequence:
1. Check DTC memory. Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase DTC memory. Diagnostic Mode 04 - Erase DTC Memory
3. If DTC memory was erased, generate readiness code.

- End diagnosis and switch ignition off.
