Diagnostic Trouble Codes (Inspection Procedure)
Check the Diagnostic Trouble Codes
1.
Turn the ignition switch to OFF.
2.
Connect the Hi-scan tool to the DLC connector for diagnosis.
3.
Turn the ignition switch to ON.
4.
Check the diagnostic trouble codes using the Hi-scan tool.
5.
Read the output diagnostic trouble codes. Then follow the remedy procedures according to the "DIAGNOSTIC TROUBLE CODE DESCRIPTION" on the following pages.
•
A maximum of 10 diagnostic trouble codes (in the sequence of occurrence) can be stored in the Random Access Memory (RAM) incorporated within the control module.
•
The same diagnostic trouble code can be stored one time only.
•
If the number of stored diagnostic trouble codes or diagnostic trouble patterns exceeds 10, already stored diagnostic trouble codes will be erased in sequence, beginning with the oldest.
•
Do not disconnect the battery until all diagnostic trouble codes or diagnostic trouble patterns have been read out, because all stored diagnostic trouble codes or diagnostic trouble patterns will be cancelled when the battery is disconnected.
•
All diagnostic trouble codes are deleted from memory the 200th time the ATF temperature reaches 50°C(122°F) after memorization of the most recent diagnostic code.
6.
Delete the diagnostic trouble code.
7.
Disconnect the Hi-scan tool.
DTC cleaning should only be done with the scan tool.
