DTC P1601 EEPROM Error - Injector Correction Value, DPNR Thermal Degradation Record


DESCRIPTION

УКАЗАНИЕ:
Whether the abnormality occurs in the DPNR catalyst thermal deterioration history data or in the injector compensation code can be determined by checking the Data List.

DTC No.
DTC Detection Condition
Trouble Area
P1601
  1. Injector compensation code is not registered
    (1-trip detection logic)
  2. Wrong injector compensation code is registered
    (1-trip detection logic)
  1. Injector compensation code
  2. ECM
  1. The DPNR catalyst thermal deterioration history data in the ECM is still the initial value
    (1-trip detection logic)
  2. The DPNR catalyst thermal deterioration history data is not recorded correctly in the ECM
    (2-trip detection logic)

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
After replacing the ECM, the new ECM needs registration (See page Нажмите здесь) and initialization (See page Нажмите здесь).
УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.CHECK IF DTC OUTPUT RECURS (IN ADDITION TO P1601)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG).

  1. Turn the tester on.

  1. Enter the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    Result:

    Result
    		Proceed to
    DTC P1601 is output
    		A
    Other DTCs is output
    		B

2.CHECK DATA LIST (INJECTOR MEMORY ERROR AND DPNR CATALYST DETERIORATE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG).

  1. Turn the tester on.

  1. Enter the following menu items: Powertrain / Engine and ECT / Catalyst Memory Error and Injector Memory Error.

    Result:

    Result
    		Proceed to
    Catalyst Memory Error: No Error
    Injector Memory Error: Error

3.CHECK INJECTOR COMPENSATION CODE

  1. Read the injector compensation codes (See page Нажмите здесь).

    OK:
    Compensation codes stored in the ECM match compensation codes of the installed injectors.
