ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Precaution for TCM 
and CVT Assembly Replacement

INFOID:0000000003848916

CAUTION:

• Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in

TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)

• When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the

TCM if necessary.

EEPROM ERASING PATTERNS

METHOD FOR ERASING THE EEPROM IN THE TCM

1.

Turn ignition switch ON.

2.

Move selector lever to “R” position.

3.

Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.

4.

Press the brake pedal and turn the brake switch ON.

5.

Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open
position. (This will set the closed throttle position signal to OFF and the wide open throttle position signal
to OFF.)

6.

Perform “ERASE”.

7.

Wait 3 seconds and then release the accelerator pedal.

8.

Turn ignition switch OFF.

METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE

In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.

1.

Erase the EEPROM in the TCM.

2.

Move selector lever to “P” position.

3.

Turn ignition switch ON.

CHECK METHOD

• Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
• Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds or

illuminates immediately.

CAUTION:

Perform in the “P” or “N” position.

Action for Non-standard

• Replace the CVT assembly.
• Replace the TCM.
