WARNING: This page is about a different variant/trim than selected.
This display indicates the ATFP control module has detected one of the following pump motor current conditions:
- At least one phase current is more than 70 A.
- Commanded current is more than 5 A and actual current in any phase is less than 2 A.
- Ignition OFF, disconnect the ATFP control module connector X2.
- Using the Auxiliary Fluid Pump Specification table listed below, test the resistance between the X2 circuits of the pump connector as indicated.
- If any of the circuits are not within the specified range, replace the pump assembly and repeat the Circuit/System Verification.
- If all circuits test normal, replace the ATFP control module and repeat Circuit/System Verification.
