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 has

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

* Shift Solenoid Valve 1

* Shift Solenoid Valve 2

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, 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 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 check 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.

Repair Instructions

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

* Control valve body replacement-Refer to Control Valve Body Replacement (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Valve Body/Service and Repair/AF40-6 - Automatic Transmission/Control Valve Body Replacement) for

replacement, setup and programming.

* 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).

Circuit/System Verification

1. Verify that DTC B1405 is not set.

瀚慖f DTC is set, refer to DTC B1405 (See: B Code Charts/B1405).

2. Verify that DTC B0958 3A, DTC B0959 3A, DTC B0960 3A, or DTC B0961 3A is not set.

瀚慖f DTC is set, replace the appropriate object alarm sensor.

3. Transmission in REVERSE, verify the parking assist system is enabled and one audible beep sounds.

Circuit/System Testing

Single Object Alarm Sensor DTC Set

1. Ignition OFF, disconnect the harness connector at the appropriate object alarm sensor.

2. Ignition OFF for 30 seconds, test for less than 20 Ohms between the low reference circuit terminal 2 and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the object

alarm module.

3. Ignition ON, transmission in REVERSE, test for 8.0-9.0 V between the voltage reference circuit terminal 1 and ground.

瀚慖f greater than the specified range, test the voltage reference circuit for a short to voltage. If the circuit tests normal, replace the object

alarm module.

瀚慖f less than the specified range, test the voltage reference circuit for a short to ground or an open/high resistance. If the circuit tests

normal, replace the object alarm module.

4. Ignition OFF, remove the malfunctioning object alarm sensor and swap locations with another properly functioning object alarm sensor.

Connect the harness connector at both sensors.

5. Ignition ON, verify the DTC is set for the new location in which the malfunctioning object alarm sensor is installed.

瀚慖f the DTC does not set for the new location, test the signal circuit terminal 3 for a short to voltage, short to ground, or an open/high

resistance. If the circuit tests normal, replace the object alarm module.

6. If the DTC sets for the new location in which the malfunctioning object alarm sensor is installed, replace the appropriate object alarm sensor.

Multiple Object Alarm Sensor DTCs Set

1. Ignition OFF, disconnect the harness connector at each of the object alarm sensors.

2. Ignition OFF for 30 seconds, test for less than 20 Ohms between the low reference circuit terminal 2 and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the object
