DTC P0500:00

DTC P0500:00

VSS circuit problem

DETECTION CONDITION

If an error in the wheel speed signal from the ABS HU/CM or DSC HU/CM is detected by CAN when the following conditions are met:
MONITORING CONDITIONS
- Neutral switch and clutch switch: off (MTX)
- Shift range: except P, N or R range (ATX)
- Absolute load: above 40 %
- Engine speed: above 2, 000 rpm
- Brake switch: off

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)/Snapshot data is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

VSS signal malfunction
- Front ABS wheel-speed sensor malfunction
- ABS HU/CM or DSC HU/CM connector or terminals malfunction
- PCM connector or terminals malfunction
- ABS HU/CM or DSC HU/CM malfunction
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data 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 ). Vehicle speed 20 km/h {12.4 mph}: 20 km/h {12.4 mph} Vehicle speed 40 km/h {24.8 mph}: 40 km/h {24.8 mph} Is the PID reading within specification?	Yes	Intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING" procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING ).
3		No	Go to the next step.
4	VERIFY DTC TROUBLESHOOTING COMPLETED Switch the ignition to ON (engine off). Clear DTC from PCM memory using M-MDS. (See AFTER REPAIR PROCEDURE ). Warm up the engine completely. Access the RPM and LOAD PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST ). Drive the vehicle under the following conditions for 18 s : Engine speed: above 2, 000 rpm Gear: except NEUTRAL Load: above 40 % Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST ). Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
4		No	Go to the next step.
5	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 ).
5		No	DTC troubleshooting completed.
