MONITOR DESCRIPTION
The ECM calculates the temperature of the MT fluid based on the voltage output by the manual transaxle oil temperature sensor (temperature sensor). If the output voltage of the manual transaxle oil temperature sensor (temperature sensor) is outside the normal range, there may be a malfunction in the manual transaxle oil temperature sensor (temperature sensor), or an open or short in the circuit. In that case, the ECM will store a DTC.
CONFIRMATION DRIVING PATTERN
HINT:
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for at least 30 seconds.
- Turn the engine switch on (IG) and wait for 3 seconds or more.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P071015.
-
Check the DTC judgment result.
Techstream Display
Description
NORMAL
- DTC judgment completed
- System normal
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
N/A
- Unable to perform DTC judgment
- Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
