- Ignition OFF, remove the Q8 Control Solenoid Valve Assembly.
- Place the Q8 Control Solenoid Valve Assembly on a clean work surface near the transmission assembly.
- Connect the DT-48616-10 adapter harness between the vehicle harness connector and the Q8 Control Solenoid Valve Assembly connector. Ignition ON.
- Test for 11-13 V between the ISS 12 V circuit terminal B on the Q8 Control Solenoid Valve Assembly X3 connector and ground.
- If not between 11-13 V
Replace the Q8 Control Solenoid Valve Assembly.
- If between 11-13 V
- If not between 11-13 V
- Verify the scan tool Transmission ISS parameter is between 495-505 RPM when performing the input shaft speed test. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test .
- If not between 495-505 RPM
Replace the Q8 Control Solenoid Valve Assembly.
- If between 495-505 RPM
- If not between 495-505 RPM
- Verify there is no damage to the reluctor, which is attached to the 4-5-6 clutch and 3-5-R clutch housing assembly, or misalignment between the B14C Transmission Input Shaft Speed Sensor and reluctor.
- If the reluctor is damaged or misaligned
Repair or replace as necessary.
- If the reluctor is not damaged or misaligned
- If the reluctor is damaged or misaligned
- Replace the B14C Transmission Input Shaft Speed Sensor.
