Disconnect the wires from the digital idle stabilizer (if it is installed) and connect them together.
Disconnect the central high-voltage wire from the ignition distributor and close it to «mass».
Connect a test lamp to the terminals «15» («+») And «1» («-») ignition coils. Turn on the starter for 5 seconds. The lamp should be flashing. If this does not happen, the ignition distribution sensor is defective and must be replaced.
Setting the ignition timing
Warm up the engine (up to a coolant temperature of at least 60°С).
Check the engine idle speed without disconnecting the vacuum hoses.
Disconnect the wires from the digital idle stabilizer (if it is installed) and connect them together.
Remove the plug from the hatch of the clutch housing, connect the stroboscope according to the instruction manual.
Note. In order to clearly see the mounting lug on the clutch housing, you should bend over the hatch of the clutch housing.
Aim a flashing stream of strobe light at the clutch housing hatch. If the ignition timing is correct, the ignition timing mark on the flywheel must be aligned with the alignment lug on the clutch cover.
To adjust, loosen the flange mounting bolt of the sensor-distributor and turn its body to align the mark with the mounting protrusion, then tighten the flange mounting bolt.
