5.3.2.11 Setup of self-diagnostic function
This self-diagnosis is practiced to Enable/Disable the error detections of the different types of
sensors.
The error detections can be disabled or enabled temporarily for troubleshooting purposes.
However, this function should be exercised with utmost care, since it is able to set some items that
require specialized knowledge in the field of operation of the engine.
After the function has been used, the set values must always be reset to the defaults.
1. Activate the self-diagnostic (Level 1) mode, and press and hold down the [MENU+] key or
[MENU-] key, until the following message appears.
2. Pressing the [ENTER] key causes the following message to appear. Press and hold down the
[MENU+] key or [MENU-], until the intended item (See the table below) is displayed.
3. Pressing the [ENTER] key allows to select the set value in the lower line of the display section.
Pressing the [MENU+] key increments the set value.
Pressing the [MENU-] key decrements the set value.
4. Pressing and holding down (3 sec) the [ENTER] key while the value you want to set remains
displayed registers that value on the EEPROM. Then, the status of Item 2 will be restored.
5. Repeat Items 2 to 4, as needed.
6. Press the [BACK] key to terminate the test. (The status of Item 1 is restored.)
