DTC P0500 [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

BME010200500201

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.
(See INTERMITTENT CONCERN TROUBLESHOOTING [AJ].)
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? (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 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.
(See PCM REMOVAL/INSTALLATION [AJ].)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [AJ].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection.
No | Troubleshooting completed.
