CONDITION SUMMARY:
REDUCED POWER OR MISFIRE AT HIGH ENGINE LOADS
Situation:
The customer may complain of reduced power and or a misfire at high engine loads and road speeds, with the possibility of Diagnostic Trouble Codes

C3006. The pump will run backwards causing the Engine Control Module (ECM) to reduce power to prevent damage because the pump flow is low. The
auxiliary coolant pump will be degraded under these conditions.

Should a customer express concern, modify the wiring at connector C3006 to the correct positions:
