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.
Scheme 2
- Connect the M-MDS to the DLC-2 connector.
- After the vehicle is identified, select the following items from the initial screen of the M-MDS. When using the IDS (laptop PC) Select "Self Test". Select "Modules". Select "ABS". When using the PDS (Pocket PC) Select "Module Tests". Select "ABS". Select "Self Test".
- Verify the DTC according to the directions on the screen. If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.
- After completion of repairs, clear all DTCs stored in the DSC. (See «CLEARING DTCS PROCEDURES»(ref-345277-S16002651752009102000000) ).
Clearing DTCs Procedures
- Connect the M-MDS to the DLC-2 connector.
- After the vehicle is identified, select the following items from the initial screen of the M-MDS. When using the IDS (laptop PC) Select "Self Test". Select "Modules". Select "ABS". When using the PDS (Pocket PC) Select "Module Tests". Select "ABS". Select "Self Test".
- Verify the DTC according to the directions on the screen.
- Press the clear button on the DTC screen to clear the DTC
- Verify that no DTCs are displayed.
PID/Data Monitor and Record Procedure
- Connect the M-MDS to the DLC-2 connector.
- After the vehicle is identified, select the following items from the initial screen of the M-MDS. When using the IDS (laptop PC) Select "DataLogger". Select "Modules". Select "ABS". When using the PDS (Pocket PC) Select "Module Tests". Select "ABS". Select "DataLogger".
- Select the applicable PID from the PID table.
- Verify the PID data according to the directions on the screen. NOTE: The PID/Data monitor function is used for monitoring the calculated value. Therefore, if the monitored value of the output parts is not within the specification, inspection of the monitored value of input parts corresponding to applicable output part control is necessary. In addition, because the system does not display output part malfunction as abnormality in the monitored value, it is necessary to inspect the output part individually using a active command modes function.
Active Command Modes Procedure
Note. Performing the active command modes function while the engine is running could result in the DTC U2064 being stored in the instrument cluster. Therefore, perform the active command mode inspection while the engine is stopped. If the active command mode inspection is accidentally performed while the engine is running, inspect the instrument cluster for the recorded DTCs, and then clear any that have been recorded.
- Connect the M-MDS to the DLC-2 connector.
- After the vehicle is identified, select the following items from the initial screen of the M-MDS. When using the IDS (laptop PC) Select "DataLogger". Select "Modules". Select "ABS". When using the PDS (Pocket PC) Select "Module Tests". Select "ABS". Select "DataLogger".
- Select the active command modes from the PID table.
- Perform the active command modes, inspect the operations for each parts. If there is no operation sound from the relay, motor, and solenoid after the active command mode inspection is performed, it is possible that there is an open or short circuit in the wiring harness, relay, motor or solenoid, or sticking and operation malfunction.
