DTC P0500:00 [MZR-CD 2.2]

DTC P0500:00	VSS circuit malfunction
DETECTION CONDITION	• The PCM monitors the vehicle speed signal from the ABS, ABS/TCS HU/CM. If the vehicle speed signal is not correct, the PCM determines that the vehicle speed signal from ABS, ABS/TCS HU/CM has malfunction. Monitoring condition • Battery voltage: more than 10 V Diagnostic support note • The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• ABS, ABS/TCS HU/CM malfunction • PCM malfunction

DTC P0500:00

VSS circuit malfunction

DETECTION CONDITION

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

Monitoring condition

• Battery voltage: more than 10 V

Diagnostic support note

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

• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

• FREEZE FRAME DATA is available.

• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• ABS, ABS/TCS HU/CM malfunction

• PCM malfunction

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED (MODE2) • Is DTC P0500:00 on FREEZE FRAME DATA (mode2)?	Yes	Go to the next step.
No	Go to troubleshooting procedures for DTC in FREEZE FRAME DATA (mode2). (See DTC TABLE [MZR-CD 2.2].)
2	VERIFY RELATED SERVICE INFORMATION • Verify 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 M-MDS to the DLC-2. • Start the engine. • Access the VSS PID. • Read the VSS PID when the vehicle is driving. • Is the VSS PID normal?	Yes	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
No	Go to the next step.
4	INSPECT ABS, ABS/TCS HU/CM • Inspect the ABS, ABS/TCS HU/CM. (See ABS HU/CM INSPECTION.) • Is there any malfunction?	Yes	Repair or replace the malfunctioning part, then go to the next step.
No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF DTC P0500:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Drive the vehicle under the FREEZE FRAME DATA condition. • Is the PENDING CODE same as the DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
No	Go to the next step.
6	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].)
No	DTC troubleshooting completed.

STEP

INSPECTION

ACTION

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED (MODE2)

• Is DTC P0500:00 on FREEZE FRAME DATA (mode2)?

Yes

Go to the next step.

Go to troubleshooting procedures for DTC in FREEZE FRAME DATA (mode2).

(See DTC TABLE [MZR-CD 2.2].)

VERIFY RELATED SERVICE INFORMATION

• Verify 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.

Go to the next step.

VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?

• Connect the M-MDS to the DLC-2.

• Start the engine.

• Access the VSS PID.

• Read the VSS PID when the vehicle is driving.

• Is the VSS PID normal?

Yes

Intermittent concern exists.

Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.

(See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)

Go to the next step.

INSPECT ABS, ABS/TCS HU/CM

• Inspect the ABS, ABS/TCS HU/CM.

(See ABS HU/CM INSPECTION.)

• Is there any malfunction?

Yes

Repair or replace the malfunctioning part, then go to the next step.

Go to the next step.

VERIFY TROUBLESHOOTING OF DTC P0500:00 COMPLETED

• Make sure to reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

• Drive the vehicle under the FREEZE FRAME DATA condition.

• Is the PENDING CODE same as the DTC present?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)

Go to the next step.

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].)
