BASIC INSPECTION

When a malfunction is not confirmed by the DTC check, 
troubleshooting should be carried out in all circuits 
considered to be possible causes of the problem. In many 
cases, by carrying out the basic engine check shown in the 
following flowchart, the location of the problem can be found 
quickly and efficiently. Therefore, using this check is essential 
when engine troubleshooting.

NOTICE:
Carry out this check with the engine stopped and ignition 
switch OFF.

REGISTRATION

NOTICE:
The Vehicle Identification Number (VIN) must be input 
into the replacement ECM.
HINT:
The VIN is in the form of a 17-digit alphanumeric vehicle 
identification number. An intelligent tester is required to 
resister the VIN.

1.

DESCRIPTION
This registration section consists of three parts, Input 
Instructions, Read VIN and Write VIN.
(a) Input Instructions: Explains the general VIN input 

instructions using an intelligent tester.

(b) Read VIN: Explains the VIN reading process in a 

flowchart. This process allows the VIN stored in the 
ECM to be read, in order to confirm that the two 
VINs, provided with the vehicle and stored in the 
vehicle's ECM, are the same.

(c) Write VIN: Explains the VIN writing process in a 

flowchart. This process allows the VIN to be input 
into the ECM. If the ECM is changed, or the VIN and 
VIN do not match, the VIN can be registered, or 
overwritten in the ECM by following this procedure.
