How to Check Idle Speed and Ignition Timing

Direct Ignition System (DIS) - How to Check Idle Speed and Ignition Timing





Method A (Using CONSULT)
Check idle speed in "DATA MONITOR" mode with CONSULT.





Method B (Using check connector)
Check the idle speed using check connector. (Check connector is located in the harness protector).

IGNITION TIMING
Any of the following two methods may be used.





Method A
1. Attach timing light to loop wire.
2. Check ignition timing.





Method B
1. Remove intake air duct.
2. Remove No.1 ignition coil.









3. Connect No.1 ignition coil and No.1 spark plug with suitable high-tension wire, and attach timing light clamp to this wire.
4. Install air duct.
5. Check ignition timing.



Target Idle Speed (*1) No-Load (*3) (In "P" or "N" position) 650 ± 50 rpm
Base Idle Speed (*2) No-Load (*3) (In "P" or "N" position) 650 ± 50 rpm

NOTE:
*1. TPS harness connector connected.
*2. Using CONSULT "WORK SUPPORT" or TPS harness connector disconnected.
*3. Under the following conditions:
- Air Conditioner Switch : OFF
- Electric Load: OFF (Lights, heater, fan & rear defogger)

Air Conditioner: ON (In "N" position) More than 700 rpm

Calculated Load Value % (Using CONSULT or GST)

At Idle 13.0 - 32.0
At 2,500 rpm 13.0 - 25.5
