PINPOINT TEST E : TRANSAXLE SOLENOID POWER CONTROL CIRCUIT

NOTE: Refer to the Transaxle Harness Connector illustration within the Transaxle Connector Layouts Transaxle Connector Layouts procedure.

NOTE: Read and record all DTCs.

E1 CHECK FOR VOLTAGE AT THE TRANSAXLE HARNESS C168

- Disconnect: Transaxle Harness C168.

- 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 at the transaxle harness C168-15, circuit CET49 (BN).






Is the voltage greater than 10 volts?

Yes
INSTALL a new solenoid body. REFER to Solenoid Body Assembly Solenoid Body Assembly. RECONNECT all components. TEST the system for normal operation.

No
GO to E2.

E2 CHECK THE TRANSAXLE SOLENOID POWER CONTROL CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: PCM C175T.

- Measure the resistance between the PCM C175T-50, circuit CET49 (BN) and transaxle harness C168-15, circuit CET49 (BN).






Is the resistance less than 5 ohms?

Yes
GO to E3.

No
REPAIR circuit CET49 (BN) 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 harness C168-15, circuit CET49 (BN) 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 CET49 (BN) for a short to ground. RECONNECT all components. TEST the system for normal operation.
