PINPOINT TEST E: TRANSAXLE SOLENOID POWER CONTROL CIRCUIT

NOTE: Refer to the Transaxle Vehicle Harness Connector illustration Transaxle Connector Layouts Symptom Related Diagnostic Procedures.

-------------------------------------------------
E1 CHECK FOR VOLTAGE AT THE TRANSAXLE VEHICLE HARNESS C168


- Disconnect: Transaxle Vehicle Harness C168.
- 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 at the transaxle vehicle 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 Transaxle C175T.
- Measure the resistance between the PCM transaxle C175T-47, circuit CET49 (BN) and transaxle vehicle 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 vehicle 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.
