DTC P0500

Vehicle speed sensor (VSS) circuit malfunction

DETECTION CONDITION

• Vehicle speed signal does not input after following conditions are met:
- Shift range in except P, N or R range
- Load is above 40%
- Engine speed is 2,000 rpm or above
Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction conditions in two consecutive drive cycles.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.

POSSIBLE CAUSE

• PCM malfunction
• Instrument cluster malfunction
• ABS HU/CM malfunction
• Open circuit between PCM terminal 58 and instrument cluster terminal 2O
• Short to ground between PCM terminal 58 and instrument cluster terminal 2O

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME PID DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME PID DATA on repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Check for related Service Information availability.
• Is any related Service Information available?
Yes
Perform repair or diagnosis according to available Service Information.
• If 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 engine.
• Access VSS PID using WDS or equivalent.
- 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}
• Are PID readings within specification?
Yes
Go to intermittent concern troubleshooting procedure.
No
Go to the next step.
4
CHECK INPUT/OUTPUT CHECK MODE
• Turn the ignition switch to the On position (Engine off).
• Is instrument cluster DTCs 10 or 12 detected?
Yes
DTC 10 and/or 12 displayed: Inspect instrument cluster.
No
Go to the next step.
5
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off.
• Disconnect PCM connector.
• Inspect for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Are terminals normal?
Yes
Go to the next step.
No
Repair or replace pin or connector, then go to Step 10.
6
INSPECT INSTRUMENT CLUSTER CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off.
• Disconnect instrument cluster connector.
• Inspect for poor connections (damaged/pulled-out terminals, corrosion, etc.).
• Are terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminals, then go to Step 10.
7
INSPECT VOLTAGE
• Connect PCM connector.
• Turn the ignition switch to the On position (Engine off).
• Measure voltage at instrument cluster terminal 2O (wiring harness-side).
• Is there 5 V at instrument cluster terminal 2O (wiring harness-side)?
Yes
Replace instrument cluster, then go to Step 10.
No
Go to the next step.
8
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch off.
• Disconnect the PCM connector.
• Turn the ignition switch to the On position (Engine off).
• Inspect for continuity between instrument cluster terminal 2O (wiring harness-side) and PCM terminal 58.
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
9
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between instrument cluster terminal 2O (wiring harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace the wiring harness, then go to the next step.
No
Replace instrument cluster, then go to the next step.
10
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.
• Warm up the engine.
• Drive vehicle under following conditions for 16 s.
- Engine speed: 2,000 rpm or above
- Gear: not in P or N range.
- Load: 40% or above
• Is the PENDING CODE of same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
