Body Electrical System > Smart key System > B1583 Park Position Error

Component Location

General Description

Personal IC Card system(hereinafter referred to PIC system) makes user more convenient by locking/unlocking door and starting engine without using mechanical key or remote controller. The push switch , attached to the Knob of the MSL, sends driver's intension for starting. If driver with PIC FOB presses push switch, SMART KEY ECU searhes FOB with valid ID inside and Once valid FOB is founded, SMART KEY ECU sends release signal to MSL. Then MSL is released by operating solenoid in MSL. After checking the change lever posion is "P", SMART KEY ECU makes engine be able to be started by transmitting key confirmation information to engine ECM.

DTC Description

The ECM sets DTC 'B1583' if the parking switch signal is detected. when the starting KNOB is in "IGN" postion and the vehicle speed exceed 3Km/h.

Monitor DTC Status

1.	Connect scantool to Data Link Connector(DLC).

2.	Engine "ON"

3.	Operate the vehicle within DTC Enable conditions in General information.

Monitor the "PARKING SW " parameter on the scantool.

Specification : "PARKING SW" parameter "OFF"

Is the monitored parameter within specifications?

	▶ Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to " Inspection/Repair " procedure.

W/Harness Inspection

1.	Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.	Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Signal(Park Position Switch) circuit ground short Inspection" procedure.

Signal(Parl Position Switch) Circuit Ground Short Inspection

1.	IG KEY : OFF.

2.	PIC IMMOBILIZER MODULE connector : Disconnect.

Measure resistance between Signal(Park Position Switch) of PIC IMMOBILIZER MODULE harness connector and chassis ground.

Specification : Infinity

Is "resistance" display near the specified value?

	▶ Go to " Component inspection " procedure.
	▶ Check for short to battery in Signal(Park Position Switch) harness. ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

Component Inspection

Check PIC Immobilizer Module

1.	IG KEY : OFF.

2.	PIC IMMOBILIZER MODULE connector : Connect.

3.	IG KEY: OFF, ENG : ON.

Measure voltage between Signal(Park Position Switch) of PIC IMMOBILIZER MODULE harness connector and chassis ground.

* Check the voltage change of signal line with operating park position switch.

Specification : park position switch → below 0V , OFF → approx. 12V

Is "voltage" display near the specified value?

	▶ Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Check for the Park Position Switch or component of SPORT MODE SWITCH. ▶ Substitute with a known-good "PIC IMMOBILIZER MODULE" and check for proper operation. If the problem is corrected, replace "PIC IMMOBILIZER MODULE" and then go to "Verification of Vehicle Repair" procedure. ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

Verification Of Vehicle Repair

After a repair, it is essential to verifying that the fault has been corrected.

1.	Connect scan tool and select "Diagnostic Trouble Codes(DTCs)" mode.

2.	Using scantool, Clear DTC.

3.	Operate the vehicle within DTC Enable conditions in General information.

Are any DTCs present ?

	▶ Go to the applicable troubleshooting procedure.
	▶ System is performing to specification at this time.
