Downloaded from www.Manualslib.com manuals search engine 6.CHECK OUTPUT SHAFT SPEED SENSOR SIGNAL
• Connect TCM and sensor connector.
• Start the vehicle and perform the following:
Engine: 2000 RPM
Vehicle: 50 km/h
Gear: 3
• Check sensor signal between sensor terminal 2 and ground in the sensor electrical connector E-089 with X-431
or oscilloscope.
• Make sure the wave shape is normal and signal voltage is fluctuating from 0-5 V.
Is the check result normal?
Ye s>>Go to step 9.
No
>>Go to the next step.
7.CHECK OUTPUT SHAFT SPEED SENSOR
• Perform the following:
Loose the bolt of the sensor.
Remove the sensor.
Visually inspect the sensor for missing or chipped teeth.
TERMINAL NO. RESISTANCE(25°C)
1-2 Except 0 or
1-3
2-3
Is the check result normal?
Ye s>>Replace the output speed sensor with a known good one.
Monitor the output speed sensor signal on the X-431 or oscilloscope.
If the output speed sensor signals were normal, the system is OK.
If the output speed sensor signals were still irregular or missing, go to step 8.
No
>>Replace output speed sensor.
8.CHECK TRANSFER CASE DRIVEN GEAR AND DRIVE GEAR
• Disassemble and repair the A/T and replace or repair the transfer case driven gear and drive gear.
• Check for a chipped and damaged signal gear of the transfer case driven and drive gear.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace or repair the transfer case driven gear and drive gear.
Monitor the output speed sensor signal on the X-431 or oscilloscope.
If the signal pulse is not normal, repair the noise interference.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• After connection, press POWER key to start X-431.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start engine then select Dposition.
• Drive the vehicle.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK BRAKE PEDAL POSITION SWITCH SIGNAL
• With the scan tool, select view DTC and data stream for A/T.
• Start vehicle and read out the value of STOP LAMP SWITCH.
ITEM CONDITIONDISPLAY
VALUE
Stop lamp switch During driving OFF
Is the check result normal?
Ye s>>The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
No

3.DETECT MALFUNCTIONING PART
• Check the following:
Harness connectors A-102, E-105
Harness for a short between TCM and brake switch
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace short to power in harness or connectors.
4.CHECK DTC
• With the X-431 scan tool, read TCM DTCs.
• Refer to DTC Confirmation Procedure.
Is DTC 26 still present?
Ye s>>Replace the TCM.
No
>>The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
