Description

Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).

The engine operating conditions (speed, load, warm-up condition, etc.) are detected by the various sensors. Based on these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The ignition coil is activated, and timing is controlled.

  1. Disconnect the injector connectors (A).
  2. Disconnect the ignition coil connectors (A). NOTE: When removing the ignition coil connector, pull the lock pin (A) and push the clip (B).
  3. Remove the ignition coils (A).
  4. Using a spark plug socket, remove the spark plugs (A). CAUTION: Be careful that no contaminates enter through the spark plug holes.
  5. Install the spark plug to the ignition coil.
  6. Ground the spark plug to the engine.
  7. Check if spark occurs while engine is being cranked. NOTE: To prevent fuel being injected from injectors while the engine is being cranked, disconnect the injector connectors. Crank the engine for no more than 5 ~ 10 seconds.
  8. Inspect all the spark plugs.
  9. Using a spark plug socket, install the spark plugs. Tightening torque: 14.7 ~ 24.5 N.m (1.5 ~ 2.5 kgf.m, 10.8 ~ 18.1 lb-ft)
  10. Install the ignition coils. Tightening torque: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) NOTE: When inserting ignition coil into the cylinder head cover for spark plug to be inserting ignition coil, the sealing cap of ignition coil must be mated totally with inner side of cylinder head.
  11. Reconnect the ignition coil connectors.
  12. Reconnect the injector connectors.
