3. | Check for continuity between the terminals according to the table.
Clutch pedal position | Stop lamp switch | Continuity
Released | Pressed | YES
Pressed | Released | NO
If the continuity is not as specified, replace the stop lamp switch. If OK, install the stop lamp switch and adjust the pedal height.
Tightening torque : 7.8~9.8Nm (0.8~1.0kgf.m, 5.8~7.2lb-ft)
Ignition Lock Switch
1. | Disconnect 2P-connector from a ignition lock switch.
2. | Disconnect the ignition lock switch. (if you can install a tester with the switch fixed, this step can be omissible)
3. | Check for continuity between terminals. (refer to the table below)
Clutch pedal position | Ignition lock switch | Continuity
Released | Released | NO
Pressed | Pressed | YES
If there is difference between what tested and the table above, replace the ignition lock switch with a new one. If not, install the ignition lock switch and adjust the clutch pedal.
Tightening torque : 7.8~9.8N.m (0.8~1.0kgf.m, 5.8~7.2lb-ft)
Concentric Slave Cylinder Air Bleeding Procedure
1. | After disconnecting a cap from the concentric slave cylinder air bleeder, insert a vinyl hose in the plug.
2. | Loosening the plug screw, press and release the clutch pedal about 10 times.
Hold the air bleeder body not to rotate with a spanner(A). The holding is needed when the plug loosened or tightened.
3. | Tighten the plug during the clutch pedal pressed. Afterwards, raise the pedal with a hand.
Tightening torque : 6.8~9.8 N.m (0.7~1.0 kgf.m, 9.2~13.3 lb-ft)
4. | After pressing the clutch pedal 3 times more, loosen the plug and retighten it with the pedal pressed. Raise it again, then.
5. | Repeat the step 4 two or three times. (until there is no bubble in the fluid)
1. | Do not clamp the pipe of a concentric slave cylinder.
2. | Be careful not to damage O-rings.
Clutch Pedal And Ignition Lock Switch
• | Inspect a ignition lock switch.
• | Remove the driver's seat mat to adjust a clutch pedal.
• | No gap between a clutch master cylinder pistion and push rod can cause clutch slip.
1. | Loosen and draw out the bolt until it is off the pedal surface.
2. | Push and pull a clutch master cylinder push rod to satisfy the specification below.
Specification: Clutch pedal stroke : 147~153 mm (5.7874~6.0236 in.) Clutch pedal free play : 6~13 mm (0.2362~0.5118 in.) Clutch pedal distance : 167 mm (6.5748 in.)
3. | With no pressure on a clutch pedal, tighten the bolt until it contacts on the pedal.
4. | Fix the bolt with a nut.
5. | Press the clutch pedal to the seat ground.
6. | Adjust the ignition lock switch position with the pedal a little(3~5mm) raised.
7. | Install the ignition lock switch firmly.
Tightening torque : 7.8~9.8N.m (0.8~1.0kgf.m, 5.8~7.2lb-ft)
