PINPOINT TEST E : TRANSAXLE SOLENOID PRESSURE CONTROL CIRCUIT

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

E1 CHECK FOR VOLTAGE AT THE TRANSAXLE VEHICLE HARNESS CONNECTOR

NOTICE: Do not use a solenoid control circuit that may be at fault. Failure to jump pin 5 to a known good solenoid control circuit can cause incorrect diagnostic results. For additional information, REFER to Diagnostic Trouble Code (DTC) Charts for a fault listing.

- Ignition OFF.

- Disconnect: Transaxle Vehicle Harness C1520A.

- Inspect the connector for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.

- Using the chart, connect a fused jumper between one of the 7 solenoid control circuit pins on the transmission vehicle harness C1520A and C1520A-5.

Transmission Vehicle Harness C1520A Solenoid Control Circuit C1520A-8 Shift Solenoid A (SSA) CET05 (BU/GN) C1520A-9 Shift Solenoid B (SSB) CET06 (GN/BN) C1520A-4 Shift Solenoid C (SSC) CET07 (GY/OG) C1520A-10 Shift Solenoid D (SSD) CET08 (BN/WH) C1520A-7 Shift Solenoid E (SSE) CET18 (GY/YE) C1520A-3 Line Pressure Control (LPC) solenoid CET09 (YE/VT) C1520A-6 Torque Converter Clutch (TCC) solenoid CET10 (BU/GY)






- Ignition ON. Measure the voltage between the transaxle vehicle harness C1520A-5 circuit CET25 (BU/GN) harness side to ground.

Is the voltage greater than 10 volts?

Yes
INSTALL a new Line Pressure Control (LPC) solenoid. REFER to 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 C1520A-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 C1520A-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.
