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.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT INPUT SIGNAL STATUS
•  Connect the M-MDS to the DLC-2.
•  Start the engine.
•  Access the VSS PID using the M-MDS.
―  Vehicle speed 20 km/h {12.4 mph}: 20km/h {12.4 mph}
―  Vehicle speed 40 km/h {24.8 mph}: 40km/h {24.8 mph}
•  Is the PID reading within specification?
Yes
Intermittent concern exists.
•  Perform the “INTERMITTENT CONCERNS TROUBLESHOOTING”.
No
Go to the next step.
4
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Switch the ignition to ON (engine off).
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
•  Access the RPM and LOAD PIDs using the M-MDS.
•  Drive the vehicle under the following conditions for 18 s:
―  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
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [LF, L5].)
No
Go to the next step.
5
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [LF, L5].)
No
DTC troubleshooting completed.
