DTC P0500 [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))


BME010200500W03

DTC P0500

Vehicle speed sensor (VSS) circuit malfunction

DETECTION CONDITION

• Vehicle speed signal from instrument cluster is below 1.88 km/h {1.17 mph} when following conditions are met:
- Shift range in expect P, N or R range
- Load is above 40%
- Engine speed is 2,000 rpm or above
- Brake switch is OFF
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.
• DTC is stored in PCM memory.

POSSIBLE CAUSE

• PCM malfunction
• Instrument cluster malfunction
• ABS HU/CM malfunction
• Open circuit between PCM terminal 79 and instrument cluster terminal 2O
• Short to ground between PCM terminal 79 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 REPAIR INFORMATION AVAILABILITY
• Check for related Service 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 WDS or equivalent to DLC-2.
• Start engine.
• Access VSS PID using the 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.
• Check 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.
• Check for poor connections (damaged/pulled-out terminals, corrosion, etc.).
• Are terminals normal?
Yes
Go to the next step.
No
Repair or replace 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 (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 the next step.
8
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch off.
• Connect the PCM connector.
• Turn the ignition switch to the ON position (Engine off).
• Check for continuity between instrument cluster terminal 2O (harness-side) and PCM terminal 79.
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace harness, then go to Step 10.
9
INSPECT INSTRUMENT CLUSTER CIRCUIT FOR SHORT TO GROUND
• Check for continuity between instrument cluster terminal 2O (harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace 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 memory using the WDS or equivalent.
• Warm up engine.
• Drive vehicle under following conditions for 16 s.
- Engine speed: 2,000 rpm or above
- Gear: not in P, N or R range.
- Load: 40% or above
• Is PENDING CODE for this DTC present?
Yes
Replace PCM, then go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
