| Removal |
| 1. |
Turn ignition switch OFF and disconnect the negative (-) battery cable. |
| 2. |
Pull up the lock of the HECU connector and then disconnect the connector (A).
|
| 3. |
Separate the brake tubes from the HECU by unlocking the nuts (6-ea) couterclockwise using a spanner.
|
| 4. |
Loosen the ESC control module mounting nut (A) and then remove the ESC control module from the vehicle.
|
| 5. |
Separate the bracket (B) after remove the mounting bolt from the HECU (A).
|
| Installation |
| 1. |
Install in the reverse order of removal. |
| 2. |
After installation, bleed the brake system. (Refer to Brake system - "Brake Bleeding Procedures") |
| 3. |
Conduct the Variant coding. |
| 4. |
Conduct the Auto Detected Sensor Calibration. |
| 5. |

| 6. |
After replacing the ESC control module execute the "Assembly Check (ECU replacement)" of the additional function to check that the mounting is successful. |
| Diagnostic procedure by using diagnostic device |
Perform diagnostic procedure by using diagnostic device as shown below:
Connect self-diagnosis connector (16pins) located under the driver side crash pad to self-diagnosis device, and then turn the self-diagnosis device after key is ON.
Select the "vehicle model" and "ABS/ESC" on KDS vehicle selection screen, then select OK.

Components and components location Components 1. ESC control module (HECU) 2. Front wheel speed sensor 3. Rear wheel speed sensor 4.
Description and operation Description 1. The ESC OFF switch is for the user to turn off the ESC system. 2.
Repair procedures Replacement 1. Remove the condenser. 2. Remove the cap (A) on the bottom of the condenser with a L wrench. Tightening torque : 9.81 - 14.71 N.
Description and operation Description The In-car air temperature sensor is built in the heater & A/C control unit. The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the resistance value which changes in accordance with perceived inside temperature, is delivered to heater co
