PROCEDURE

1. ECU EXCHANGE

NOTICE:

• When replacing the engine stop and start ECU, make sure to download the number of starter operations (step 1). After replacing the engine stop and start ECU (step 2), write the number of starter operations to the new engine stop and start ECU (step 3).
• After replacing the engine stop and start ECU, make sure to perform external backup boost converter (eco run vehicle converter assembly) existence learning (step 4).
• Even if the number of starter operations could not be downloaded, after replacing the engine stop and start ECU with a new one, make sure to perform external backup boost converter (eco run vehicle converter assembly) existence learning (step 4).

(a) Download the engine stop and start ECU data. (Step 1)

(1) Enter the following menus.

Powertrain > Stop and Start > Utility

Tester Display
ECU Exchange

(2) According to the display on the GTS, select "Step 1 Save" and then "Next" to download the ECU data from the engine stop and start ECU.

(b) Replace the engine stop and start ECU. (step 2)

(1) Replace the engine stop and start ECU.

(c) Write the engine stop and start ECU data to the new engine stop and start ECU. (Step 3)

(1) Enter the following menus.

Powertrain > Stop and Start > Utility

Tester Display
ECU Exchange

(2) According to the display on the GTS, select "Step 3 Write" and then "Next" to write the ECU data to the new engine stop and start ECU.

(d) Perform external backup boost converter (eco run vehicle converter assembly) existence learning. (Step 4)

(1) According to the display on the GTS, select "Step 4 Learning" and then "Next" to perform external backup boost converter (eco run vehicle converter assembly) existence learning.

HINT:

• If the external backup boost converter (eco run vehicle converter assembly) existence value of the old engine stop and start ECU differs from the current learned value or if data could not be downloaded from the old engine stop and start ECU, the learning result will be displayed.
• If the external backup boost converter (eco run vehicle converter assembly) existence value of the old engine stop and start ECU was "available" but the value after replacement is "not available", the external backup boost converter (eco run vehicle converter assembly) may not be connected securely. Check the connector connection condition and perform learning again.

2. CLEAR NUMBER OF STARTER OPERATIONS

NOTICE:

• After the starter assembly is replaced, be sure to clear the number of starter operations stored in the engine stop and start ECU.
• When the starter assembly is replaced, "ST relay" must be also replaced.

(a) Enter the following menus.

Powertrain > Stop and Start > Utility

Tester Display
Starter Exchange

(b) Following the prompts on the GTS display, clear the number of starter operations.

(c) Check the Vehicle Control History (RoB) and clear X0877 if it is output.

3. RESET AIR CONDITIONING INFORMATION

NOTICE:

After replacing the engine stop and start ECU or air conditioning amplifier assembly, initialization of the air conditioning information in the engine stop and start ECU is necessary.

(a) Enter the following menus.

Powertrain > Stop and Start > Utility

Tester Display
Reset A/C Information

(b) Following the prompts on the GTS display, clear the A/C information.

4. LEARNING AIR CONDITIONING INFORMATION

HINT:

When initialization of the air conditioning information is complete, air conditioning information learning is automatically performed. If the learning cannot be performed properly, inspect the CAN communication system.

5. CLEAR THE INTEGRATED CURRENT VALUE

HINT:

If the integrated current value does not exceed the threshold*1 even though the auxiliary battery has been charged until the auxiliary battery current decreases to 5 A or less, perform an integrated current value initialization.

• *1: Refer to System Description for details on the integrated current threshold.

(a) Enter the following menus.

Powertrain > Stop and Start > Utility

Tester Display
Integrated Current Value Initialization

6. SWITCH BATTERY TYPE

(a) Check whether the auxiliary battery is specified or not specified.

(b) Turn the ignition switch to ON.

HINT:

Do not start the engine.

(c) Enter the following menus.

Powertrain > Stop and Start > Data List

Tester Display
Battery Type

HINT:

Check the auxiliary battery type (Specified/Other) stored by the engine stop and start ECU.

(d) If the auxiliary battery installed does not match the auxiliary battery stored by the ECM, switch to the battery type for the installed auxiliary battery.

(1) Enter the following menus.

Powertrain > Engine > Utility

Tester Display
Switch Battery Type

7. AIR BLEED OIL PUMP WITH MOTOR ASSEMBLY

NOTICE:

Bleed the oil pump with motor assembly after replacing the continuously variable transaxle assembly or replacing the CVT fluid.

(a) Turn the ignition switch to ON.

HINT:

Do not start the engine.

(b) Enter the following menus.
