P0717
DTC P0717: Input shaft 1 (odd number gear axle) speed sensor system (Output current low 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) speed sensor is determined to be too low.
MONITOR EXECUTION
^ Continuous
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
^ P0715: Input shaft 1 (odd number gear axle) speed sensor system (Output high range out)
^ P0716: Input shaft 1 (odd number gear axle) speed sensor system (Poor performance)
^ P2766: Input shaft 2 (even number gear axle) speed sensor system (Poor performance)
Sensor (The sensor below is determined to be normal)
^ Input shaft 2 (even number gear axle) speed 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: 1.5 seconds or more.
JUDGMENT CRITERIA
^ Sensor current: 4 mA or less. (500 millisecond)
OBD-II DRIVE CYCLE PATTERN
The sensor current remains 4 mA or more for 500 milliseconds.
PROBABLE CAUSES
^ Malfunction of TC-SST-ECU
^ Malfunction of input shaft 1 speed sensor
DIAGNOSTIC PROCEDURE
Required Special Tools:
^ MB991958: Scan Tool (M.U.T.-III Sub Assembly)
^ MB991824: Vehicle Communication Interface (V.C.I.)
^ MB991827: M.U.T.-III USB Cable
^ MB991910: M.U.T.-III Main Harness A
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.
After 5 or more seconds have passed with the engine idle status, check that the DTC is reset.
Q: Is DTC No. P0717 set?
YES: Replace the mechatronic assembly.
NO: Intermittent malfunction.
