STR_AB_EST
°
Steering wheel position when vehicle wheels straight-ahead
0 °
•  Perform the DTC inspection for the PCM, DSC HU/CM, and EPS control module. If a DTC is displayed after performing the DTC inspection for the PCM, DSC HU/CM, and EPS control module, repair the malfunctioning part according to the applicable DTC troubleshooting.
•  After performing the DTC inspection, perform the following procedures:
―  Switch the ignition off and maintain condition for approx. 3 s.
―  Switch the ignition ON (engine off or on).
―  Set the vehicle wheels straight-ahead, then drive the vehicle straight at 20 km/h {12 mph} or more for 5 s or more.
―  Using the M-MDS, verify the STR_ANG_EST operation condition.
•  If an abnormal value is indicated after verifying the value of the STR_AB_EST ANG again, replace the EPS control module.
Steered left
Changes to 0 °—positive
Steered right
Changes to 0 °—negative
Note
•  The monitor item STR_AB_EST indicates steering angle (estimated absolute angle).
STR_ANG
°
Steering wheel position when ignition is switched ON (engine off or on)
0 °
•  Perform the DTC inspection for the PCM, DSC HU/CM, and EPS control module. If a DTC is displayed after performing the DTC inspection for the PCM, DSC HU/CM, and EPS control module, repair the malfunctioning part according to the applicable DTC troubleshooting.
•  After performing the DTC inspection, perform the following procedures:
―  Switch the ignition off and maintain condition for approx. 3 s.
―  Set the vehicle wheels straight-ahead.
―  Switch the ignition ON (engine off or on).
―  Using the M-MDS, verify the STR_ANG operation condition.
•  If an abnormal value is indicated after verifying the value of the STR_ANG again, replace the EPS control module.
Steered left
Changes to 0 °—positive
Steered right
Changes to 0 °—negative
Note
•  The monitor item STR_ANG indicates steering angle (relative angle).
•  The monitor item STR_ANG indicates the steering position when the ignition is switched ON as 0 °. Therefore, the steering position when the ignition is switched ON while the steering wheel is being operated is indicated as 0 °. In this case, 0 ° is not indicated even if the steering position is in the straight-ahead position.
•  To indicate monitor item STR_ANG as 0 ° when the steering position is in the straight-ahead position, perform the following procedure.
1.  Set the steering wheel in the straight-ahead position.
2.  Switch the ignition OFF (LOCK) and hold for approx. 2 min.
3.  Switch the ignition ON (engine off or on).
―  If monitor item STR_ANG is not indicated as 0 °, perform the following procedure.
1.  Set the steering wheel in the straight-ahead position.
2.  Switch the ignition OFF (LOCK) and hold for approx. 10—30 min.
3.  Switch the ignition ON (engine off or on).

VPWR
V
This PID indicates power supply voltage for EPS control module.
•  Inspect the battery.
•  Inspect power supply circuit (push button start, IG1 relay, fuse etc.)
VSPD
KPH, MPH
This PID indicates vehicle speed.
•  Inspect the DSC HU/CM.
