PINPOINT TEST E: ELECTRONIC PCB

NOTE: Refer to the Transaxle 5th Gear Valve Body Vehicle Harness Connector illustration Transaxle Connector Layouts Transaxle Connector Layouts.

NOTE: Read and record all DTCs. All Transmission Range (TR) sensor and Output Shaft Speed (OSS) DTCs must be repaired before entering output state control.

-------------------------------------------------
E1 CHECK THE TRANSAXLE 5TH GEAR VALVE BODY VEHICLE HARNESS FOR A SHORT TO POWER


- Ignition OFF.
- Disconnect: Transaxle 5th Gear Valve Body Vehicle Harness C1535.
- Disconnect: TCM C2352A.
- Ignition ON.
- Measure the voltage between transaxle 5th gear valve body vehicle harness C1535-2, circuit CET45 (YE/BU) and ground.




- Is any voltage present?

Yes
REPAIR circuit CET45 (YE/BU) for a short to power. TEST the system for normal operation.

No
GO to E2.

-------------------------------------------------
E2 CHECK THE TRANSAXLE 5TH GEAR VALVE BODY VEHICLE HARNESS FOR A SHORT TO GROUND


- Measure the resistance between transaxle 5th gear valve body vehicle harness C1535-2, circuit CET45 (YE/BU) and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to E3.

No
REPAIR circuit CET45 (YE/BU) for a short to ground. TEST the system for normal operation.

-------------------------------------------------
E3 CHECK THE TRANSAXLE 5TH GEAR VALVE BODY VEHICLE HARNESS FOR AN OPEN


- Measure the resistance between transaxle 5th gear valve body vehicle harness C1535-2, circuit CET45 (YE/BU) and TCM C2352A.




- Is the resistance less than 5 ohms?

Yes
GO to E4.

No
REPAIR circuit CET45 (YE/BU) for an open. TEST the system for normal operation.

-------------------------------------------------
E4 CHECK THE PCB TRANSAXLE INTERNAL HARNESS FOR A SHORT TO GROUND


- Ignition OFF.
- Remove the 5th gear valve body cover. Refer to Main Control FNR5.
- Disconnect: Pressure Control Solenoid B (PCB) Solenoid Electrical Connector.
- Measure the resistance between transaxle 5th gear valve body vehicle harness C1535-2 (component side, transaxle internal harness) and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to E5.

No
INSTALL a new transaxle internal harness. TEST the system for normal operation.

-------------------------------------------------
E5 CHECK THE TRANSAXLE INTERNAL HARNESS FOR AN OPEN


- Measure the resistance between transaxle C1535-2, and PCB component side transaxle 5th gear valve body internal harness pin 2.




- Measure the resistance between ground and PCB component connector pin 3.




- Are the resistances less than 5 ohms?

Yes
GO to E6.

No
INSTALL a new transaxle internal harness. TEST the system for normal operation.

-------------------------------------------------
E6 CHECK SOLENOID RESISTANCE AT THE SOLENOID


- Measure the resistance between PCB solenoid pins.




- Is the resistance between 2.0 and 7.3 ohms?

Yes
GO to E7.

No
INSTALL a new PCB solenoid. TEST the system for normal operation.

-------------------------------------------------
E7 CHECK THE SOLENOID FOR A SHORT TO GROUND


- Measure the resistance between the PCB solenoid pins and the solenoid body.




- Is the resistance greater than 10,000 ohms?

Yes
REFER to Diagnosis By Symptom Diagnosis By Symptom for diagnosis of pressure concerns. TEST the system for normal operation.

No
INSTALL a new PCB solenoid. TEST the system for normal operation.
