P1701
* DTC P1701 is Type B DTC.
* Measured gear ratio deviates less than 4% from expected ratio.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the TCM is warmed up and the transmission is operated in 2nd gear long enough to ensure
a 3掳C (5掳F) increase in TCM substrate temperature. This will place the TCM under the optimal conditions to test solenoid electrical DTCs.

Circuit/System Verification
1. Verify the transmission fluid level , color and odor is correct.
2. Operate the vehicle to induce a shift from fifth to sixth gear while observing the following scan tool parameters. The scan tool parameters
have to change the proper value referring to the current gear. Compare the proper values with Transmission System Description and
Operation (M36 and MXE) (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Description and Operation/AF40-6 -
Automatic Transmission/Transmission System Description and Operation (M36 and MXE)). Perform this action 2 times.
* Clutch Pressure Control Solenoid Valve 1 Current
* Clutch Pressure Control Solenoid Valve 2 Current
* Clutch Pressure Control Solenoid Valve 3 Current
* Brake Band Pressure Control Solenoid Valve Current
瀚慖f the scan tool parameter does not change the proper value and no other DTC than P0729, P0731, P0732, P0733, P0734, P0735, P0736,
P0780, P1701, P1731 is set, go to circuit/system testing.
瀚慖f any other DTC is set, diagnose that DTC first.
Circuit/System Testing
Dynamic Test
1. Perform the Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Symptom
Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Line Pressure Check).
2. 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).
3. If all circuits test normal, replace the K71 Transmission Control Module. Verify the DTC does not reset.
瀚慖f the DTC resets, replace the control valve body.
