Replacement
  

Back-up battery (BUB) embedded in the E-call system has a finite lifespan and its charging/discharging performance may be diminished after an extensive use.

The back-up battery guarantees the operation of the E-call system when the vehicle battery cannot be used due to an accident. Be sure to inspect the back-up battery if the red LED turns on and replace it if necessary.

Warranty on Back-up Battery is 3 years.

Inspect the back-up battery every three years and replace it if necessary.

1.

Remove the E-call unit.

(Refer to Emergency Call System - "Emergency Call Unit")

2.

Replace the back-up battery after opening the cover (A).

Inspection

Diagnosis with KDS

The diagnostic system (KDS) provides the following information.

(1)

Self diagnosis : Checks failure and code number (DTC)

(2)

Current data : Checks the system input/output data state

(3)

Actuation test : Checks the system operating condition

(4)

Additional function : Controls other features including system option setting and zero point adjustment

2.

Select the 'Car model' and the 'Telematics System' to be checked in order to check the vehicle with the tester.

3.

Select the 'Current Data' menu to check the current state of the input/output data.
