DIS - How to Check Idle Speed and Ignition Timing

- Using CONSULT
Check idle speed in "DATA MONITOR" mode with CONSULT

IGNITION TIMING
Any of following two methods may be used.




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




- Method B
1. Remove No.1 ignition coil.










2. Connect No.1 ignition coil and No.1 spark plug with suitable high-tension wire as shown, and attach timing light clamp to this wire.
3. Check ignition timing.

Target Idle Speed(*1) No-Load(*3) (in "N" position) M/T: 625 ± 50 rpm
A/T: 700 ± 50 rpm
(in "N" position)

Base idle speed(*2) No-Load(*3) (in "N" position) M/T: 575±50 rpm
A/T: 650 ±50 rpm
(in "N" position)

NOTE:
*1 Throttle position sensor harness connector connected.
*2 Throttle position sensor harness connector disconnected or using CONSULT "WORK SUPPORT".
*3 Under the following conditions:
- Air conditioner switch: OFF
- Electric load: OFF (Heater, fan & rear window defogger)

CALCULATED LOAD VALUE
Calculated load value %
(Using CONSULT or GST)

At idle 14.0 - 33.0
At 2,500 rpm 12.0 - 25.0
