DTC P0500

DTC P0500

VSS circuit problem

DETECTION CONDITION

The PCM monitors the input signal from the vehicle speed sensor when the following conditions are met. If the input signal is less than 3.7 km/h {2.3 mph} , the PCM determines that there is a VSS circuit malfunction.

MONITORING CONDITIONS

Shift lever position: gear is not in neutral position
Engine speed: more than 2, 500 rpm
LOAD: more than 40.0%

Diagnostic support note

This is a continuous monitor (CCM).
The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA (Mode 2/Mode 12) is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

ABS HU/CM malfunction (with ABS HU/CM)
DSC HU/CM malfunction (with DSC HU/CM)
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 12) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY CURRENT INPUT SIGNAL STATUS Start the engine. Access the VSS PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST ). Read the VSS PID when the vehicle is driving. Is the VSS PID normal? (See PCM INSPECTION ).	Yes	intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING". (See INTERMITTENT CONCERN TROUBLESHOOTING ).
3		No	Go to the next step.
4	INSPECT ABS HU/CM OR DSC HU/CM Inspect the ABS HU/CM (with ABS HU/CM). (See ABS HU/CM INSPECTION ). Inspect the DSC HU/CM (with DSC HU/CM). (See DSC HU/CM INSPECTION ). Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF DTC P0500 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE ). Drive the vehicle under the FREEZE FRAME DATA (Mode 2) condition. Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST ). Is the PENDING CODE same as the DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE ". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
6		No	DTC troubleshooting completed.
