Test Drive Code 1015 and TPMS

This guide explains how to check Test Drive Code 1015 errors, missing top speed and driving distance, TPMS non-reception, and overpressure NG.

Symptoms

• When entering the test drive, the error 'There are no Test Drive items (Code: 1015)' or 'Failed to read 5 times - Code 1015' occurs.
• Despite driving at or above the specified speed, the top speed (Top Speed) is recorded as low on the results screen, or the driving distance is missing and shown as 0.
• After the test drive, the TPMS tyre pressure value is 0 (not received), or requirements are not met (NG) at 38~39 psi.

Causes

• When vehicles are inspected consecutively using 1 PIM, the previous vehicle's test drive cache may remain.
• If the tablet screen turns off or 'battery power saving mode' activates while driving, Bluetooth data collection is temporarily suspended.
• The permitted TPMS pressure range is 28.0 ~ 37.0 psi.

Resolution

Code 1015 3-step check

1. When vehicles are inspected consecutively using 1 PIM, the previous vehicle's test drive cache may remain, so completely close the app and then restart it.
2. The test drive must be entered with the engine running (Engine ON / READY for EVs) and all doors, the boot and the bonnet closed.
3. Apply the latest app version and diagnostic DB updates over Wi-Fi.

Preventing missing top speed/distance

On the tablet, set [설정] > [디스플레이] > [화면 자동 꺼짐 시간] to 10 minutes or longer, disable power saving mode, and register the app as excluded from battery optimisation.

TPMS non-reception (0 psi)

To wake up the TPMS sensors, drive continuously at 30km/h or faster for 10 minutes or longer.

TPMS overpressure NG (38~39 psi)

The permitted pressure range is 28.0 ~ 37.0 psi, so reduce the pressure of tyres inflated to high pressure for shipping to around 35 psi before completing.
