DTC P0500 - 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.
1		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 Bulletins 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.
2		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. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
3		No	Go to the next step.
4	CHECK INPUT/OUTPUT CHECK MODE Turn key to ON (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 .)
4		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 okay?	Yes	Go to the next step.
5		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 okay?	Yes	Go to the next step.
6		No	Repair or replace terminals, then go to Step 10.
7	INSPECT VOLTAGE Connect PCM connector. Turn key to ON (engine OFF). Measure voltage at instrument cluster terminal 20 (harness-side). Is there 5 V at instrument cluster terminal 20 (harness-side)?	Yes	Replace instrument cluster, then go to Step 10. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
7		No	Go to the next step.
8	INSPECT INSTRUMENT CLUSTER CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch off. Connect breakout box with PCM connector disconnected. Turn key to ON (engine OFF). Check for continuity between instrument cluster terminal 20 (harness-side) and breakout box terminal 79. Is there continuity?	Yes	Go to the next step.
8		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 20 (harness-side) and body ground. Is there continuity?	Yes	Repair or replace harness, then go to the next step.
9		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 seconds. Engine speed: 2,000 RPM or above Gear: not in P or N position. Load: 40% or above Is PENDING CODE for this DTC present?	Yes	Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION .)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection.
11		No	Troubleshooting completed.
