TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS

id020200800200

On-Board Diagnostic (OBD) Test Description

―  Provides a quick inspection of the TPMS usually performed at the start of each diagnostic procedure.

―  Provides verification after repairs to ensure that no other faults occurred during service.

―  Read/clear diagnostic results, and PID monitor.

Read/clear diagnostic results

•  This function allows you to read or clear DTCs in the instrument cluster memory.

PID/Data monitor and record

•  This function allows you to access certain data values, input signals, calculated values, and system status information.

Reading DTCs Procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

•  When using the IDS (laptop PC)

1.  Select “Self Test”.

2.  Select “Modules”.

3.  Select “IC”.

•  When using the PDS (Pocket PC)

1.  Select “Module Tests”.

2.  Select “IC”.

3.  Select “Self Test”.

3.  Verify the DTC according to the directions on the screen.

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.

4.  After completion of repairs, clear all DTCs stored in the instrument cluster. (See DTC TABLE [INSTRUMENT CLUSTER].)

Clearing DTCs Procedures

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

•  When using the IDS (laptop PC)

1.  Select “Self Test”.

2.  Select “Modules”.

3.  Select “IC”.

•  When using the PDS (Pocket PC)

1.  Select “Module Tests”.

2.  Select “IC”.

3.  Select “Self Test”.

3.  Verify the DTC according to the directions on the screen.

4.  Press the clear button on the DTC screen to clear the DTC.

5.  Switch the ignition to off.

6.  Switch the ignition to ON and wait for 5 s or more.

7.  Perform DTC inspection. (See DTC Table.)

8.  Verify that no DTCs are displayed.

PID/Data Monitor and Record Procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

•  When using the IDS (laptop PC)

1.  Select “DataLogger”.

2.  Select “Modules”.

3.  Select “IC”.

•  When using the PDS (Pocket PC)

1.  Select “Module Tests”.

2.  Select “IC”.

3.  Select “DataLogger”.

3.  Select the applicable PID from the PID table.

4.  Verify the PID data according to the directions on the screen.

Note

•  The PID data screen function is used for monitoring the calculated value of input/output signals in the module.Therefore, if the monitored value of the output parts is not within the specification, it is necessary to inspect the monitored value of input parts corresponding to the applicable output part control. In addition, because the system does not display an output part malfunction as an abnormality in the monitored value, it is necessary to inspect the output parts individually.

PID/DATA Monitor Table

Note

•  When the wheel unit is in sleep mode, the data logger displays a value different from the actual value. (Such as, WU1_P:0 KPa, WU1_T:-50 °C)

PID Name (Definition)	Unit/ Condition	Condition/Specification	Action
WU1_ID WU2_ID WU3_ID WU4_ID (Wheel unit ID code)	–	Indicates the registered ID that is transmitted from the wheel unit.	•  Replace the wheel unit. •  Perform the wheel unit ID registration.
WU1_P WU2_P WU3_P WU4_P (Tire pressure)	Pa, psi	Indicates the tire pressure. (See WHEEL AND TIRE SPECIFICATION [European (L.H.D. U.K.) Specs.].)	•  Adjust tire pressure. •  Replace the wheel unit. •  Perform the wheel unit ID registration.
WU1_T WU2_T WU3_T WU4_T (Tire temperature)	°C, °F	Indicates the internal tire air temperature.	Adjust tire pressure.
WU1_VPWR WU2_VPWR WU3_VPWR WU4_VPWR (Supply voltage)	Normal/Error	Signal is normal: Normal Signal is abnormal: Error	Replace the wheel unit.
WU1_ERR_T WU2_ERR_T WU3_ERR_T WU4_ERR_T (Tire temperature)	Normal/Error	Signal is normal: Normal Signal is abnormal: Error	Replace the wheel unit.
WU1_ERR_P WU2_ERR_P WU3_ERR_P WU4_ERR_P (Tire pressure)	Normal/Error	Signal is normal: Normal Signal is abnormal: Error	Replace the wheel unit.
