IGNITION TIMING INSPECTION [ZJ, ZY]

id0110000636b7

  Note

  • The ignition timing cannot be adjusted.
  • The WDS or equivalent is required to verify the ignition timing.

1. Complete the engine tune-up preparation.

  Note

  • Use a timing light that can detect the primary ignition signal.

2. By referring to the following procedure, connect the timing light to the PCM terminal 2A wire.

  Caution

  • To prevent poor contact at the connector terminal, be careful not to pull the wire on the connector side.

  Note

  • Pull out the wire 20-30 mm so that the pickup clip of the timing light can be connected. After the ignition timing inspection, bundle the pulled out wire back together with other wires using tape.

  (1) Pull the PCM terminal 2A wire out of the bundle (pull the bundled side only, not the connector side).
  (2) Connect the pickup clip of the timing light to the PCM terminal 2A wire.

3. Verify that the crankshaft pulley alignment mark (white) is within the specification.

Ignition timing (Test mode on)

  BTDC 9-11°

4. Turn the test mode off using a simulation test.

5. Using the timing light, verify again that the crankshaft pulley alignment mark (white) is within the specification.

  • If not within the specification, inspect the following parts:

  - CMP sensor
  - CKP sensor
  - TP sensor
  - ECT sensor
  - TR switch (ATX vehicle)
  - Neutral/clutch switch (MTX vehicle)

Ignition timing (Test mode off)

  BTDC 6-18°
