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
When either condition below is met:
  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
When either condition below is met:
  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 RAV4_ACA30 RM000000TJ4007X.html) and initialization (see page RAV4_ACA30 RM000000TIN007X.html).
1.CONFIRM ECM

  1. Confirm if DTC P1601 was output because a new ECM was installed.
