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 CONDITION
– 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 is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• DSC HU/CM malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED

• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2

VERIFY RELATED REPAIR INFORMATION AVAILABILITY

• Verify related service 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.
No
Go to the next step.
3

VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?

• Connect the WDS or equivalent to the DLC-2.
• Start the engine.
• Access the VSS PID.
• Read the VSS PID when the vehicle is driving.
• Is the VSS PID normal?
Yes
Intermittent concern exists.
Perform the "INTERMITTENT CONCERNS TROUBLESHOOTING".
No
Go to the next step.
4

INSPECT DSC HU/CM

• Inspect the DSC HU/CM.
• Is there any malfunction?
Yes
Repair or replace the malfunctioning part, then go to the next step.
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 WDS or equivalent.
• Drive the vehicle under the FREEZE FRAME DATA condition.
• Is the PENDING CODE same as the DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
6

VERIFY AFTER REPAIR PROCEDURE

• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
