id041800817200

1.  Turn the ignition switch off.

2.  Remove the combined sensor installation nut.

3.  Connect the M-MDS to the DLC-2.

4.  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 “ABS”.

•  When using the PDS (Pocket PC)

1.  Select “Module Tests”.

2.  Select “ABS”.

3.  Select “DataLogger”.

5.  Select the following PIDs, then inspect the lateral acceleration speed, longitudinal acceleration speed, roll rate and yaw rate.

―  LAT_ACCL: (lateral acceleration speed)

―  ACCLMTR: (longitudinal acceleration speed)

―  YAW_RATE: (yaw rate)

―  ROLL_RATE (roll rate)

(1)  Lateral acceleration speed inspection

1)  Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.

•  If there is any malfunction, replace the combined sensor.

Standard

When the sensor is tilted to the right (A): LAT_ACCL changes negatively.

When the sensor is tilted to the left (B): LAT_ACCL changes positively.

(2)  Longitudinal acceleration speed inspection

1)  Verify the ACCLMTR change when the combined sensor is moved forward and backward.

•  If there is any malfunction, replace the combined sensor.

Standard

When the sensor is tilted to forward (A): ACCLMTR changes negatively.

When the sensor is tilted to backward (B): ACCLMTR changes positively.

(3)  Yaw rate inspection

1)  Verify the YAW_RATE change when the combined sensor is rotated to the left and right.

•  If there is any malfunction, replace the combined sensor.

Standard

When the sensor is rotated to the right (A): YAW_RATE changes positively.

When the sensor is rotated to the left (B): YAW_RATE changes negatively.

(4)  Roll rate inspection

1)  Verify the ROLL_RATE change when the combined sensor is tilted to the left and right.

•  If there is any malfunction, replace the combined sensor

Standard

When the sensor is tilted to the right (A): ROLL_RATE changes positively

When the sensor is tilted to the left (B): ROLL_RATE changes negatively
