CHECK INJECTOR COMPENSATION CODE
DTC P0603 Internal Control Module Keep Alive Memory (KAM) Error |
- ПРИМЕЧАНИЕ:
- When an injector is replaced, the injector's compensation code must be input into the ECM.
When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM. - An injector compensation code is a unique, 10-digit alphanumeric code imprinted on the head portion of an injector. If an incorrect injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.
| When you replace the ECM with a new one, input all the injectors' compensation codes into the new ECM as follows: |
Prior to replacing the ECM, read and save each injector's compensation code, stored in the original ECM, using an intelligent tester (See page Нажмите здесь).
After installing a new ECM, input the saved compensation codes into the new ECM using the tester (See page Нажмите здесь).
Turn the tester off.
Wait for at least 30 seconds.
Turn the ignition switch to the ON position.
Turn the tester on.
Clear DTC P0603 stored in the ECM using the tester (See page Нажмите здесь).
- УКАЗАНИЕ:
- Each injector has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses the compensation codes to balance the different fuel injections between each injector.
- When you first turn the ignition switch to the ON position after replacing the ECM or an injector(s), DTC P0603 is set. This is to inform you that an injector compensation code(s) is/are required to be registered. Manually clear the DTC upon completion of the compensation code registration.
DESCRIPTION
| DTC No. | DTC Detection Condition | Trouble Area |
| P0603 | Injector compensation code is not registered (The MIL is illuminated and a DTC is immediately set when a malfunction is detected) |
|
- УКАЗАНИЕ:
- DTC P0603 is set when the ignition switch is in the ON position.
INSPECTION PROCEDURE
| 1.CHECK INJECTOR COMPENSATION CODE |
Check the injector compensation codes (See page Нажмите здесь).
- OK:
- The compensation codes stored in the ECM match the compensation codes of the installed injectors.
