| Fixed Idle Ignition Timing | Ignition timing is set depending on the engine speed. | Idling | ||
| Idle Speed Control | Idle speed can be set. | Idling | ||
| Injection Stop Mode (Injector 1) Injection Stop Mode (Injector 2) Injection Stop Mode (Injector 3) Injection Stop Mode (Injector 4) |
Injector of each cylinder can be set to stop the fuel injection. | Idling | ||
| Alternator control | Alternator control mode can be set to one of the followings:
|
Idling | ||
| Injection Volume - Port Injection Injection Volume - Direct Injection Injection Volume - Injection of Control Depending |
The fuel injection method can be set to the cylinder injection or the port injection. The amount of fuel injection can be set.
NOTE:
Statuses of the front oxygen (A/F) sensor and the rear oxygen sensor can be checked by increasing/decreasing the fuel injection volume.
|
|
||
| Target Fuel Pressure | The fuel pressure can be set. | Engine speed: 3000 rpm or less | ||
| Fuel Injection Period - Injector 1 Fuel Injection Period - Injector 2 Fuel Injection Period - Injector 3 Fuel Injection Period - Injector 4 Fuel Injection Period - All Injector |
The fuel injection period can be set. |
|
||
| Activate the ACC Cut Relay | ON/OFF of the ACC cut relay operation can be set. |
|
||
| Control the ETCS Open/Close | The throttle valve operation can be set to throttle open/throttle closed. |
|
||
| Power balance (injection stop) - Port Injection Power balance (injection stop) - Direct Injection Power balance (injection stop) - Injection of Control Depending |
The fuel injection method for each cylinder can be set to the cylinder injection or the port injection. The fuel injection for each cylinder can be stopped. |
|
||
| Power balance (injection ignition stop) - Port Injection Power balance (injection ignition stop) - Direct Injection Power balance (injection ignition stop) - Injection of Control Depending |
The fuel injection method for each cylinder can be set to the cylinder injection or the port injection. The fuel injection and ignition for each cylinder can be stopped. |
|
||
| Control the All Cylinders Fuel Cut | The fuel injection for all cylinders can be stopped.
NOTE:
It is possible to check the ignition system for abnormality by stopping the fuel injection during startup cycle and allowing ignition operation only.
|
|
||
| Check the Cylinder Compression | The engine speed during cranking can be measured. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>ACTIVE TEST>LIST>CHECK THE CYLINDER COMPRESSION .
NOTE:
Fuel injection and ignition for all cylinders are stopped, cranking is performed for approx. 10 seconds, and engine speed for each cylinder is measured.
|
|
||
| Injection Mode Change | The fuel injection method can be switched to the following.
|
|
||
| Starter cut relay | ON/OFF of the starter cut relay operation can be set. |
|
||

Intake oil control solenoid operation can be set to -27 - 36°CA in increments of 1°CA. |
CAUTION:
|
||
| Control the VVT Exhaust Linear (Bank1) Control the VVT Exhaust Linear (Bank2) |
Exhaust oil control solenoid operation can be set to 0 - 51°CA in increments of 1°CA. | |||
