DTC P0500 [MZR-CD (RF Turbo)]

BME010200500W07

DTC P0500

VSS circuit malfunction

DETECTION CONDITION

• PCM monitors input vehicle speed signal from instrument cluster while engine is running. If input vehicle speed signal from instrument cluster is 0 km/h {0 mph} when gear is in position other than neutral, clutch pedal is depressed and engine speed is 2,800 rpm or above, PCM determines VSS circuit malfunction.

POSSIBLE CAUSE

• ABS HU/CM malfunction
• Instrument cluster malfunction
• Connector or terminal malfunction
• Short to GND in wiring between instrument cluster terminal 2O and PCM terminal 6
• Open circuit in wiring between instrument cluster terminal 2O and PCM terminal 6
• Short to GND in wiring between ABS HU/CM terminal Q and instrument cluster terminal 2G
• Open circuit in wiring between ABS HU/CM terminal Q and instrument cluster terminal 2G
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Check for related Service Information availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to available Service Information.
• If vehicle is not repaired, go to next step.
No
Go to next step.
2
VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT
• Start engine.
• Access VSS PID using WDS or equivalent.
- Vehicle speed 20 km/h {12.5 mph}: 20 km/h {12.5 mph}
- Vehicle speed 40 km/h {25 mph}: 40 km/h {25 mph}
• Is VSS PID readings within specification?
Yes
Intermittent concern exists. Go to "Intermittent Concern Troubleshooting".
No
Go to next step.
3
CHECK INPUT/OUTPUT CHECK MODE
• Turn engine switch to ON (Engine OFF).
• Is instrument cluster DTC 10 or 12 detected?
Yes
DTC 10 and/or 12 displayed: inspect instrument cluster.
No
Go to next step.
4
INSPECT POOR CONNECTION OF INSTRUMENT CLUSTER CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace suspected terminal, go to Step 8.
No
Go to next step.
5
INSPECT VEHICLE SPEED SIGNAL CIRCUIT FOR SHORT TO GND
• Turn engine switch to OFF.
• Inspect continuity between instrument cluster terminal 2O and body GND.
• Is there continuity?
Yes
Repair or replace harness for short to GND, go to Step 8.
No
Go to next step.
6
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace suspected terminal, go to Step 8.
No
Go to next step.
7
INSPECT VEHICLE SPEED SIGNAL CIRCUIT FOR OPEN
• Turn engine switch to OFF.
• Inspect continuity between instrument cluster terminal 2O and PCM terminal 6.
• Is there continuity?
Yes
Go to next step.
No
Repair or replace harness for open, go to next step.
8
VERIFY TROUBLESHOOTING OF DTC P0500 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear DTC from PCM memory using WDS or equivalent.
• Start engine.
• Is same DTC present?
Yes
Replace PCM, go to next step.
No
Go to next step.
9
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
