PINPOINT TEST E: TRANSAXLE SOLENOID PRESSURE CONTROL CIRCUIT

NOTE: Refer to the Transaxle Vehicle Harness Connector illustration Transaxle Connector Layouts Transaxle Connector Layouts.

-------------------------------------------------
E1 CHECK FOR VOLTAGE AT THE TRANSAXLE VEHICLE HARNESS CONNECTOR


- Disconnect: Transaxle Vehicle Harness C168a.
- Use a mirror to inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
- Ignition ON.
- Measure the voltage between the transaxle vehicle harness C168a-5, circuit CET25 (BU/GN) and ground.




- Is the voltage greater than 10 volts?

Yes
INSTALL a new Transaxle Pressure Control Solenoid. REFER to Solenoids 6F35 Solenoids. RECONNECT all components. TEST the system for normal operation.

No
GO to E2 .

-------------------------------------------------
E2 CHECK THE TRANSAXLE SOLENOID PRESSURE CONTROL CIRCUIT FOR AN OPEN


- Ignition OFF.
- Disconnect: PCM Transaxle Harness C175T.
- Measure the resistance between the PCM transaxle C175T-50, circuit CET25 (BU/GN) and transaxle vehicle harness C168-5, circuit CET25 (BU/GN).




- Is the resistance less than 5 ohms?

Yes
GO to E3.

No
REPAIR circuit CET25 (BU/GN) for an open. RECONNECT all components. TEST the system for normal operation.

-------------------------------------------------
E3 CHECK THE TRANSAXLE SOLENOID POWER CONTROL CIRCUIT FOR A SHORT TO GROUND


- Measure the resistance between the transaxle vehicle harness C168a-5, circuit CET25 (BU/GN) and ground.




- Is the resistance greater than 10,000 ohms?

Yes
INSTALL a new PCM. RECONNECT all components. TEST the system for normal operation.

No
REPAIR circuit CET25 (BU/GN) for a short to ground. RECONNECT all components. TEST the system for normal operation.
