Inspection
Self Diagnosis With Scan Tool Smart key system defects can be quickly diagnosed with the GDS. GDS operates actuator quickly to monitor, input/output value 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.
The following three diagnostic solutions will be the main solution process to a majority of concerns.
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
Switch Diagnosis
1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel, turn the power on GDS.
2. | Select the vehicle model and then SMART KEY system.
3. | Select the "SMART KEY unit".
4. | After IG ON, select the "Current data".
5. | You can see the situation of each switch on scanner after connecting the "current data" process.
