Ignition Timing: Testing and Inspection

1. WARM UP ENGINE.
- Allow the engine to warm up to normal operating temperature.





2. CONNECT TACHOMETER AND TIMING LIGHT TO ENGINE.
- Connect the tester probe of a tachometer to terminal IG(-) of the DLC1.

HINT: Set the tachometer to the 4-cylinder range.

NOTICE:
- Never allow the tachometer terminal to touch ground as it could result in damage to the igniter and/or ignition coil.
- As some tachometers are not compatible with this ignition system, we recommend that you confirm the compatibility of your unit before use.





3. CHECK IGNITION TIMING.
- Using SST 09843-18020, connect terminals TE1 and E1 of the DLC1.





- Connect the tester probe of a timing light to the high-tension cord for No.6 cylinder.





- Using a timing light, check the ignition timing.

Ignition timing: 8 - 12° BTDC @ idle
(Transmission in neutral position)

- If the ignition timing is not as specified, check that following conditions are normal:
- Throttle valve fully closed
- Continuity between terminals IDL1 and E2 of the throttle position sensor
- Valve timing





- Remove the SST from the DLC1.
4. DISCONNECT TACHOMETER AND TIMING LIGHT FROM ENGINE.
