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".
(See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
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? (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE.) | Yes | DTC 10 and/or 12 displayed: inspect instrument cluster. (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE.)
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. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Is there any DTC present? | Yes | Go to applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
