ON-BOARD DIAGNOSIS
On-Board Diagnostic (OBD) Test Description
- The OBD test inspects the integrity and function of the DSC and outputs
the results when requested by the specific tests.
- On-board diagnostic test also:
- Provides a quick inspection of the DSC usually performed at the
start of each diagnostic procedure.
- Provides verification after repairs to ensure that no other faults
occurred during service.
- The OBD test is divided into 3 tests:
- Read/clear diagnostic results, PID monitor and record and active
command modes.
Read/clear diagnostic results
- This function allows you to read or clear DTCs in the DSC HU/CM memory.
PID/Data monitor and record
- This function allows you to access certain data values, input signals,
calculated values, and system status information.
Active command modes
- This function allows you to control devices through the M-MDS.
Reading DTCs Procedure
1. Connect the M-MDS (IDS) to the DLC-2.
2. After the vehicle is identified, select the following items from the
initialization screen of the IDS.
- Select "Self Test".
- Select "Modules".
- Select "ABS".
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 DSC. (See
Clearing DTCs Procedures).
Clearing DTCs Procedures
1. Connect the M-MDS (IDS) to the DLC-2.
2. After the vehicle is identified, select the following items from the
initialization screen of the IDS.
- Select "Self Test".
- Select "Modules".
- Select "ABS".
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 Reading DTCs Procedure).
8. Verify that no DTCs are displayed.
PID/Data Monitor and Record Procedure
1. Connect the M-MDS (IDS) to the DLC-2.
2. After the vehicle is identified, select the following items from the
initialization screen of the IDS.
- Select "DataLogger".
- Select "Modules".
- Select "ABS".
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.
Active Command Modes Procedure
1. Connect the M-MDS (IDS) to the DLC-2.
2. After the vehicle is identified, select the following items from the
initialization screen of the IDS.
- Select "DataLogger".
- Select "Modules".
- Select "ABS".
3. Select the simulation items from the PID table.
4. Perform the active command modes function, inspect the operations for each
parts.
- If the operation of output parts cannot be verified after the active
command mode inspection is performed, this
could indicate the possibility of an open or short circuit, sticking, or
operation malfunction in the output parts.
