HOW TO PROCEED WITH TROUBLESHOOTING

CAUTION / NOTICE / HINT

HINT:

The power back door system troubleshooting procedure is based on the premise that the smart key system (for Entry Function, HV Model) is operating normally. Check the power back door system first before troubleshooting the power back door system.

Use the following procedure to troubleshoot the power back door system.
*: Use the Techstream.

PROCEDURE

1.	VEHICLE BROUGHT TO WORKSHOP

2.	CUSTOMER PROBLEM ANALYSIS AND SYMPTOM CHECK

3.	READ AND SAVE OPERATION HISTORY

NOTICE:

If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before operation history has been read out and saved, the operation history information could be lost.
The function "Read operation history" uses the current system time setting inside the Techstream and the time counter inside the controlling ECU to calculate the timings shown in the operation history. For this reason, before reading out the operation history, first make sure that the Techstream system clock is accurately set to the current time.

(a) Read and save operation history using the Techstream.

4.	INSPECT AUXILIARY BATTERY VOLTAGE

(a) Measure the auxiliary battery voltage with the power switch off.

Standard voltage:

11 to 14 V

HINT:

A simple method to determine whether the auxiliary battery is discharged is to operate the horn.
If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding.

(b) Check the fuses and relays.

(c) Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

5.	CHECK COMMUNICATION FUNCTION OF LIN COMMUNICATION SYSTEM*

(a) Using the Techstream, check for LIN communication system DTCs.

10.	ADJUST, REPAIR OR REPLACE

(a) Check whether the replacement, removal and installation of the multiplex network door ECU or disconnection of the connectors of the multiplex network door ECU, the disconnection of the cable of the negative (-) auxiliary battery terminal with the back door open, or the removal and installation or replacement of the power source system fuses has been performed.

Result	Proceed to
The replacement, removal and installation of the multiplex network door ECU or disconnection of the connectors of the multiplex network door ECU, the disconnection of the cable of the negative (-) auxiliary battery terminal with the back door open, or the removal and installation or replacement of the power source system fuses has been performed.	A
The replacement, removal and installation of the multiplex network door ECU or disconnection of the connectors of the multiplex network door ECU, the disconnection of the cable of the negative (-) auxiliary battery terminal with the back door open, or the removal and installation or replacement of the power source system fuses has not been performed.
