Circuit/System Verification
1. Review the Failure Records when the DTC set.
锟斤拷If the engine coolant temperature (ECT) was above 125锟斤拷C (257锟斤拷F) when the DTC set, go to Symptoms - Engine Cooling (See: Engine,
Cooling and Exhaust/Cooling System/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Cooling) and
correct that concern first.
2. Perform the Transmission Fluid Cooler Flushing and Flow Test (J 45096) (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/2ML70 - Automatic Transmission/Transmission
Fluid Cooler Flushing and Flow Test (J 45096)).
Circuit/System Testing
1. Review the Failure Records when the DTC set.
2. Compare the MTS values for each drive motor generator.
锟斤拷If both MTS values were not at or near 200锟斤拷C (392锟斤拷F), test the MTS signal circuit for a low resistance to ground condition.
锟斤拷If the circuit tests normal, replace the drive motor generator.
3. Inspect the transmission cooling system for restrictions or damage.
锟斤拷If a concern is found, repair or replace the restricted or damaged components as necessary.
4. Perform the Transmission Fluid Cooler Flushing and Flow Test (J 45096) (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/2ML70 - Automatic Transmission/Transmission
Fluid Cooler Flushing and Flow Test (J 45096)).
锟斤拷If a concern is found, repair or replace the damaged components as necessary.
5. Perform the automatic transmission Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Component Tests and General Diagnostics/2ML70 - Automatic Transmission/Line Pressure Check).
锟斤拷If a concern is found repair or replace the damaged components as necessary.
Component Testing
* Perform the Fluid Leak Diagnosis (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component
Tests and General Diagnostics/2ML70 - Automatic Transmission/Fluid Leak Diagnosis).
* Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing
and Inspection/Symptom Related Diagnostic Procedures/2ML70 - Automatic Transmission/Transmission Fluid Level and Condition Check)
procedure.
* Perform the Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component
Tests and General Diagnostics/2ML70 - Automatic Transmission/Line Pressure Check) procedure.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Drive Motor with Generator Assembly Removal - 1st Position (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Service and Repair/Overhaul/2ML70 - Automatic Transmission/8. Drive Motor with Generator Assembly Removal -
1st Position).
* Transmission Control Wiring Harness Extension Harness Removal (See: Transmission and Drivetrain/Automatic
