Initial Inspection and Diagnostic Overview

Inspection

Self Diagnosis With Scan Tool
It will be able to diagnose defects of SMART KEY system with scan tool quickly. Scan tool can operates actuator forcefully, input/output value monitoring and self diagnosis.
The following three features will be major problem in SMART KEY system.
1. Problem in SMART KEY unit input.
2. Problem in SMART KEY unit.
3. Problem in SMART KEY unit output.
So the following three diagnosis operates will be the major problem solution process.
1. SMART KEY unit Input problem : switch diagnosis
2. SMART KEY unit problem : communication diagnosis
3. SMART KEY unit Output problem : antenna and switch output diagnosis

2. Select the "STATUS CHECK".




3. After IG ON, select the "SRx COMM. LINE STATUS CHECK".




4. Check the serial communication line with a scanner.
5. If the smart key works normally, the communication of smart key unit, exterior receiver are normal.
6. If the smart key does not work properly, check the following items.
A. Disconnection or no response of the exterior receiver communication line.
B. The exterior receiver communication line disconnection and ground connection.

ESCL Communication Status Check
1. Connect the cable of scan tool to the data link connector in driver side crash pad lower panel.
2. Select the "STATUS CHECK".




3. After IG ON, select the "ESCL COMM. LINE STATUS CHECK".




4. Check the ESCL communication line with a scanner.
5. If the smart key works normally, the communication of ESCL(Electronic Steering Column Lock) is normal.
6. If the smart key does not work properly, check the following items.
A. The ESCL disconnection or no response
B. The ESCL disconnection and ground connector

Interior Antenna Actuation Check
1. Set the smart key in the following shade area and check the IG ON.




2. If the ignition is ON, the antenna works normally.
3. Check the interior antenna ignition mode.
4. Set the smart key in the following shade area and actuate the antenna. Check the LED of smart key is blinking.




5. If the LED of smart key is not blinking, check the antenna in shade area.
