Problem detected in air conditioning electrical circuit. Location and pinouts for the Diagnostics Connector. The fix for the condition is a PCM replacement, not a reprogramming of the controller. trans. An open or shorted condition detected in the speed control servo power control circuit (SBECII: external relay). If you receive this message on Jeep Grand Cherokee (or another car): "Update Failed. Check the coolant level and condition. This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The check engine light on the dash of the 91 to 96 Jeep Cherokees displays ECU codes, which can be accessed by looking at the light. Idle Air Control Motor Circuit input above acceptable current. A rationality error has been detected for park/neutral switch performance. An open or shorted condition detected in the EVAP purge solenoid control circuit. CODE U1504 FIX DODGE JEEP CHRYSLER FIATIf you have engine light on and code U1504 on your Dodge, Jeep, Chrysler or Fiat car we will show you what needs to be.
