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
>>Go to the next step.

Downloaded from www.Manualslib.com manuals search engine 2.CHECK BRAKE SWITCH POWER SUPPLY
• Stop vehicle.
• Check sensor power supply between sensor terminal 3 and ground in the sensor electrical connector C-005.
BRAKE SWITCH
CONDITION VALUE (VOLT)
Depress brake switch
Battery voltage
Release brake switch 0
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the brake switch.
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.

Diagnostic Procedure
1.CHECK GROUND CONNECTION
• Turn ignition switch off.
• Loosen and retighten ground screws on the body (See Ground Inspection in Section 12 Brakes).
• Inspect the ground connection C-201 mounting position (See Vehicle Wiring Harness Layout - Main Harness in
Section 16 Wiring).
Are the ground connections OK?
Ye s>>Go to the next step.
No
>>Repair or replace the ground connections.
