REGISTRATION
NOTICE:
The Vehicle Identification Number (VIN) must be input
into the replacement ECM.
HINT:
The VIN is a 17-digit alphanumeric vehicle identification
number. The intelligent tester is required to register the VIN.
1. INPUT INSTRUCTIONS
(a) The general VIN input instructions using the
intelligent tester are shown below:
(b) The arrow buttons (UP, DOWN, RIGHT and LEFT)
and numerical buttons (0 to 9) are used to input the
VIN.
(c) Cursor Operation
To move the cursor around the tester screen, press
the RIGHT and LEFT buttons.
(d) Alphabetical Character Input
(1) Press the UP and DOWN buttons to select the
desired alphabetical character.
(e) Numerical Character Input
(1) Press the numerical button corresponding to
the number that you want to input.
HINT:
Numerical characters can be selected by using
the UP and DOWN buttons.
(f) Correction
(1) When correcting the input character(s), put the
cursor onto the character using the RIGHT and
LEFT buttons.
(2) Select or input the correct character using the
UP and DOWN buttons, or the numerical
buttons.
(g) Finishing Input Operation
(1) Make sure that the input VIN matches the
vehicle VIN after input.
(2) Press the ENTER button on the tester.
2. READ VIN (Vehicle Identification Number)
(a) The VIN reading process is shown in the flowchart
below. Reading the VIN stored in the ECM is
necessary when comparing it to the VIN provided
with the vehicle.
(b) Read the VIN using the intelligent tester.
(c) Check the vehicle's VIN.
(d) Connect the intelligent tester to the DLC3.
(e) Turn the ignition switch to the ON position.

3. WRITE VIN
(a) The VIN writing process is shown in the flowchart
below. This process allows the VIN to be input into
the ECM. If the ECM is changed, or the ECM VIN
and Vehicle VIN do not match, the VIN can be
registered, or overwritten in the ECM by following
this procedure.
(b) Write VIN using the intelligent tester.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.

(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Check that the MIL turns off.
(4) Under CURRENT DATA, the throttle valve
opening percentage (THROTTLE POS) should
be within the standard range below.
Standard throttle valve opening percentage:
