Variable Induction System: Testing and Inspection

1. WARM UP AND STOP ENGINE.
2. CONNECT TACHOMETER.



- Connect the tester probe of a tachometer to terminal IG(-) of the DLC1.

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. CONNECT VACUUM GAUGE.



- Using a 3 - way connector, connect the vacuum gauge to the hose between the VSV and actuator.

4. CHECK VACUUM GAUGE.
- Check that the vacuum gauge indicates vacuum at idling.
- Check that the vacuum gauge indicates zero at 4,200 rpm or more.

HINT: If regular unleaded gasoline is used, the vacuum gauge also indicates zero below 4,200 rpm.

5. DISCONNECT TACHOMETER.
