Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information



Circuit/System Verification



1. Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing



and Inspection/Symptom Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Transmission Fluid Level and Condition Check)



to verify correct fluid level.



2. Engine idling at operating temperature, observe the scan tool Transmission Fluid Temperature parameter. The reading should be between -40



to +215掳C (-40 to +488掳F) and change.



3. Operate the vehicle at about 60 km/h (37 MPH) for 10 min. Verify the scan tool Transmission Fluid Temperature parameter varies by more



than 2掳C (3.5掳F) to verify that the sensor is not stuck.



Circuit/System Testing



Operate the vehicle within the conditions for running and setting the DTC to verify the DTC does not reset. You may also operate the vehicle



within the conditions that you observed from the Freeze Frame/Failure Records data.



Component Testing



Static Test



1. Ignition OFF, remove the K71 Transmission Control Module.



2. Ignition OFF, test for infinite resistance between the low reference circuit terminal 7 X2 and ground.



瀚慖f less than the specified range, replace the wiring harness.



3. Ignition OFF, test for infinite resistance between the signal circuit terminal 8 X2 and ground.



瀚慖f less than the specified range, replace the wiring harness.



4. Test for infinite resistance between each terminal and the low reference circuit terminal 7 X2 and also to the signal circuit terminal 8 X2.



瀚慖f less than the specified range, replace the wiring harness.



5. Test for the resistance between the B13 Automatic Transmission Fluid Temperature Sensor signal circuit terminal 7 X2 and the low reference



circuit terminal 8 X2. Refer to Transmission Fluid Temperature Sensor Specifications (See: Transmission and Drivetrain/Automatic



Transmission/Transaxle/Specifications/Pressure, Vacuum and Temperature Specifications) for the resistance values.



瀚慖f not within the specified range, replace the wiring harness.



6. If the circuit test normal, replace the K71 Transmission Control Module.



Repair Instructions



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.



* Wiring harness-Refer to Automatic Transmission Wiring Harness Replacement (See: Transmission and Drivetrain/Automatic



Transmission/Transaxle/Wiring Harness/Service and Repair) for replacement.



* TCM-Refer to Control Module References (See: Testing and Inspection/Programming and Relearning) for replacement, setup, and



programming.



* Perform the Transmission Adaptive Functions (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Description and



Operation/AF40-6 - Automatic Transmission/Transmission Adaptive Functions).



P0716



DTC P0716 or P0717



Diagnostic Instructions



* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System



Check - Vehicle) prior to using this diagnostic procedure.



* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an



overview of the diagnostic approach.



* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure



Instructions) provides an overview of each diagnostic category.
