DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is functioning
properly. If outputs from the CPUs are different and deviate from the standard, the ECM will illuminate the MIL
and store a DTC immediately.
DTC NO.

Unable to perform DTC judgment
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
11.
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and
check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE
NOTICE:
After turning ignition switch off, waiting time may be required before disconnecting the cable from the
negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the
negative (-) battery terminal notices before proceeding with work
.
HINT:
Read freeze frame data using the Techstream. 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, if
the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1.
CHECK DTC
(a) Clear DTC
