DTC P0500:00 [MZR-CD 2.2]

id0102f3704800

DTC P0500:00

VSS circuit problem

DETECTION CONDITION

•  The PCM monitors the vehicle speed signal from the DSC HU/CM. If the vehicle speed signal is not correct, the PCM determines that the vehicle speed signal from the DSC HU/CM has a malfunction.

MONITORING CONDITIONS

―  Battery voltage: 10 V or more

Diagnostic support note

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  DSC HU/CM DTC is stored.

•  ABS wheel-speed sensor connector or terminals malfunction

•  ABS wheel-speed sensor malfunction

•  PCM connector or terminals malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY STORED DTC IN DSC HU/CM • Retrieve the DSC HU/CM DTC using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
3		No	Go to the next step.
4	VERIFY CURRENT INPUT SIGNAL STATUS • Start the engine. • Access the VSS PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].) ― 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} • Is the PID reading within specification?	Yes	Intermittent concern exists. • Perform the “INTERMITTENT CONCERN TROUBLESHOOTING” procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4		No	Go to the next step.
5	INSPECT ABS WHEEL-SPEED SENSOR CONNECTOR CONDITION • Switch the ignition to off. • Disconnect the ABS wheel-speed sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
5		No	Go to the next step.
6	INSPECT ABS WHEEL-SPEED SENSOR • Inspect the ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR INSPECTION.) (See REAR ABS WHEEL-SPEED SENSOR INSPECTION.) • Is there any malfunction?	Yes	Replace the ABS wheel-speed sensor, then go to Step 8. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.) (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to the next step.
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Drive the vehicle under the FREEZE FRAME DATA (Mode 2) condition. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
9		No	DTC troubleshooting completed.
