P0715

DTC P0715: Input shaft 1 (odd number gear axle) speed sensor system (Output high range out)

CAUTION:
^ If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
^ Whenever the ECU is replaced, ensure that the CAN bus lines are normal.

DIAGNOSTIC FUNCTION
TC-SST-ECU checks that the input shaft 1 (odd number gear axle) speed sensor is normal.

DESCRIPTIONS OF MONITOR METHODS
The output of the input shaft 1 (odd number gear axle) is determined to be too high.

MONITOR EXECUTION
^ Continuous

MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)

LOGIC FLOW CHARTS (Monitor Sequence)





DTC SET CONDITIONS

Check Conditions
^ Voltage of battery: 8 V or more.
^ Voltage of battery: 16.5 V or less.
^ Time after engine start: 400 millisecond or more.

JUDGMENT CRITERIA
^ Sensor current: 17 mA or more. (500 millisecond)

OBD-II DRIVE CYCLE PATTERN

PROBABLE CAUSES
^ Malfunction of TC-SST-ECU

DIAGNOSTIC PROCEDURE

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.

Q: Is the check result normal?
YES: Go to Step 2.
NO: Repair the CAN bus lines. After repairing the CAN bus line, go to Step 2.

STEP 2. Check whether the DTC is reset.

Q: Is DTC No. P0715 set?
YES: Replace the TC-SST assembly.
NO: Intermittent malfunction.
