Circuit/System Verification
WARNING: This page is about a different variant/trim than selected.
- Verify that DTC B1433 is not set.
- If the DTC is set, refer to DTC B1433 .
- Ignition ON, engine OFF, command the Aux. Trans. Pump Speed to 50 percent with the scan tool, maintain pump operation for at least 60 seconds while observing the hybrid powertrain control module aux. trans. fluid pump actual and the aux. trans. fluid pump commanded parameter. The actual parameter should remain within 10 percent of commanded value during the 60 second test.
- If not within the specified range, refer to Circuit System Testing .
- While commanding the aux. trans. fluid pump speed to 50 percent observe and record the hybrid powertrain control module Aux. Trans. Fluid Pump Fault Status 1 and the hybrid powertrain control module Aux. Trans. Fluid Pump Fault Status 2 parameters. Both readings should display No Fault.
- If the reading displays No PWM Response, refer to Circuit System Testing .
