DTC P0500 [L3]

BME010200500W01

DTC P0500

Vehicle speed sensor (VSS) circuit malfunction

DETECTION CONDITION

• Vehicle speed signal is not input after following conditions are met:
- Gear is in position other than neutral position
- 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 or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• 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
• Connector or terminal malfunction
• Instrument cluster malfunction
• ABS, ABS/TCS, DSC HU/CM malfunction
• Open circuit between PCM terminal 2L and instrument cluster terminal 2O
• Short to ground between PCM terminal 2L 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 next step.
No
Record FREEZE FRAME PID DATA on repair order, then go to 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 next step.
No
Go to next step.
3
VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT
• Connect WDS or equivalent to 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 next step.
4
CHECK INPUT/OUTPUT CHECK MODE
• Turn ignition key to ON (engine OFF).
• Is instrument cluster DTCs 10 or 12 detected?
Yes
DTC 10 and/or 12 displayed: Inspect instrument cluster.
No
Go to next step.
5
INSPECT INSTRUMENT CLUSTER CONNECTOR FOR POOR CONNECTION
• Turn ignition key to OFF.
• Disconnect instrument cluster connector.
• Inspect for poor connections (damaged/pulled-out terminals, corrosion, etc.).
• Are terminals okay?
Yes
Go to next step.
No
Repair or replace terminals, then go to Step 10.
6
INSPECT VOLTAGE
• Connect PCM connector.
• Turn ignition key to ON (engine OFF).
• Measure voltage at instrument cluster terminal 2O (harness-side).
• Is there 5 V at instrument cluster terminal 2O (harness-side)?
Yes
Replace instrument cluster, then go to Step 10.
No
Go to next step.
7
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR SHORT TO GROUND
• Turn ignition key to OFF
• Inspect for continuity between instrument cluster terminal 2O (harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace harness, then go to Step 10.
No
Go to next step.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn ignition key to OFF.
• Disconnect PCM connector.
• Inspect for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Are terminals okay?
Yes
Go to next step.
No
Repair or replace pin or connector, then go to Step 10.
9
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR OPEN
• Turn ignition key to OFF.
• Turn ignition key to ON (engine OFF).
• Inspect for continuity between instrument cluster terminal 2O (harness-side) and PCM terminal 2L (harness-side).
• Is there continuity?
Yes
Replace instrument cluster then go to next step.
No
Repair or replace harness, then go to next step.
10
VERIFY TROUBLESHOOTING OF DTC P0500 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear DTC from memory using WDS or equivalent.
• Warm up engine.
• Drive vehicle under following conditions for 16 s.
- Engine speed: 2,000 rpm or above
- Gear: Gear is in position other than neutral
- Load: 40% or above
• Is PENDING CODE of same DTC present?
Yes
Replace PCM, then go to next step.
No
Go to next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC troubleshooting.
No
Troubleshooting completed.
