2. Connect the tachometer and stroboscope. Connect the probe of the tachometer tester to the output "IG" (-) diagnostic socket.
3S-FE, 4S-FE, 4A-FE, 7A-FE. | 3S-GE, 5E-FE. |
Note:
- Never let the tachometer lead touch "land", as this may cause damage to the switch and/or ignition coil.
- Some tachometers are not compatible with this ignition system, so please check the compatibility of your instrument before use
3. Adjust ignition timing
A) Use a jumper to bridge the leads "TE1" And "E1" diagnostic socket.
3S-FE, 4S-FE, 4A-FE, 7A-FE. | 3S-GE, 5E-FE. |
b) Bring the engine to the speed mode of 1000-1500 min-1 and hold it in this mode for 5 seconds, then make sure that after releasing the throttle, it returns to normal idle
V) Using a stroboscope, check the ignition timing.
Ignition timing at idle:
- 3S-FE, 3S-GE, 4S-FE - 8-12°to TDC
- 4A-FE, 5E-FE, 7A-FE - 10°BTDC
(with the jumper closed and the automatic transmission selector in position "N")
G) If necessary, loosen the two bolts and adjust the ignition timing by turning the distributor housing (integrated ignition unit).
d) Tighten the two bolts and recheck the ignition timing.
Torque:
- all engines - 20 Nm
- 3S-GE - 39 Nm
e) Remove the jumper from the diagnostic socket.
4. Recheck ignition timing
Ignition timing at idle:
- 3S-FE, 3S-GE - 10-20°BTDC
- 4A-FE, 7A-FE - 5-15°BTDC
- 5E-FE - 6°-18°BTDC
Note: The timing mark on the crankshaft pulley moves between the values specified for each engine.
5. Remove the tachometer and stroboscope.
