Testing clutch pedal switch -F36- The clutch pedal switch -F36- signal serves to avoid overspeed and load alteration shocks when declutching. Special tools and workshop equipment required t  Vehicle system tester -V.A.G 1552- t  Diagnostic cable -V.A.G 1551/3- or -V.A.G 1551/3A- or -V.A.G 1551/3B- t  Hand multimeter (e.g. -V.A.G 1526 A-) t  Adapter cable set (e.g. -V.A.G 1594 A-) t  Test box -V.A.G 1598/31- Test condition l  Fuse no. 43 o.k. Check for proper operation –  Connect vehicle system tester -V.A.G 1552-. Switch ignition on and then select “address word” 01 Engine electronics → Chapter. –  Select function 08 “read measured value block” and display group number 006.

–  Readout on display: –  Observe the display in display field 2.    Specified value:    0XX (if clutch pedal not pressed)    1XX (if clutch pedal pressed) –  Select function 06 “End output” and confirm with Q. –  Switch off ignition. –  If the display does not occur as described: Testing switch –  Remove lower part of the dash panel insert on the driver's side → Body Work; Rep. Gr.70. –  Unplug connector at the clutch pedal switch.

Reading measured value block 6 -> 0 km/h 000 0 % 0

–  Connect handheld multimeter for resistance measurement between contact 2 and 3.    Specified value: max. 1.5 Ω –  Actuate clutch pedal.    Specified value: ∞ Ω (no continuity) If the specified value is not reached: –  Replacing the clutch pedal switch. If the specified values are reached: Checking voltage supply –  Switch on ignition.   Note 2- and 4-pin versions of the connector are used.

–  Connect the handheld multimeter with adapter cables from -V.A.G 1594 A- to the 4-pin plug as follows:

3 + earth	approx. battery voltage

–  Connect the handheld multimeter with adapter cables from -V.A.G 1594 A- to the 2-pin plug as follows:

2-pin plug on wiring loom, contact	Specification
1 + earth	approx. battery voltage

If the specified value is not reached: –  Check the wiring of contact 2 (4-pin plug) or of contact 1 (2-pin plug) of the plug and fuse 28 for interruption or short-circuit to earth → Current flow diagrams and Fitting locations. –  If necessary eliminate wire interruption or short-circuit. If the specified value is reached: Testing the wiring –  Switch off ignition.   Note 2- and 4-pin versions of the connector are used. –  Connect test box -V.A.G 1598/31- to the wiring loom on the engine control unit → Chapter.

–  Check the following wiring on the 4-pin plug for interruption and short-circuit to earth or positive:
