NO : Replace TCM.

DTC P1706: Malfunction of Throttle Signal

.

DIAGNOSTIC FUNCTION

TCM detects the abnormality in the throttle position
signal sent from the ECM.

.

DESCRIPTIONS OF MONITOR METHODS

• The difference between the throttle position sig-

nal received from the ECM and the correspond-
ing turnover value is 1.37 V or more, and this
status continues for 1 second.

.

MONITOR EXECUTION

• Transmission range: D

.

DIAGNOSTIC PROCEDURE

STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.
Use scan tool MB991958 to perform the CAN bus diagnosis.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Repair the CAN bus lines (Refer to GROUP 54C

−

Troubleshooting, Diagnostic Trouble Code Chart

P.54C-19

).

STEP 2. Scan tool MB991958 diagnostic trouble code
Check if the engine-related diagnostic trouble code is set.
Q: Is diagnostic trouble code set?

YES : Diagnose the engine control system.
NO : Go to Step 3.

STEP 3. Symptom recheck after erasing diagnostic trouble
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO : Replace TCM.

DTC P1710: Malfunction of Vehicle Speed Signal

.

DIAGNOSTIC FUNCTION

TCM conducts fault detection by detecting the rapid
change in the estimated vehicle speed signal
received from the ABC-ECU.

.

JUDGMENT CRITERIA

• Difference between the estimated vehicle speed

and the one measured before 0.1 second is 29
km/h (18.0 mph) or more.

• The status with the vehicle speed of 10 km/h (6.2

mph) or more and with the estimated vehicle
speed of 2 km/h (1.2 mph) or less continues for
20 seconds.

.

PROBABLE CAUSES

• Malfunction of the CAN bus

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. Troubleshoot the CAN system if diagnosis code
U0121 is set.
Q: Is the diagnosis code U0121 set?

YES : Diagnose the CAN system.
NO : Go to Step 2.

DIAGNOSIS

TSB Revision

CVT

23A-96

STEP 2. M.U.T.-III data list

• Item 21: Vehicle speed (inference)

• Item 22: Real vehicle speed

OK: Vehicle speed signal and vehicle speed do not dif-
fer greatly.

Q: Is the check result normal?

YES : Intermittent malfunction
NO : Go to Step 3.

STEP 3. Check ABS-related diagnosis codes.
Q: Is the ABS-related diagnosis code set?

YES : Carry out the appropriate troubleshooting.
NO : Go to Step 4.

STEP 4. Symptom recheck after erasing diagnosis code
Q: Is the check result normal?

YES : Intermittent malfunction
NO : Replace TCM.
