CONDITION SUMMARY:
SITUATION:
A loud noise can be heard coming from the engine compartment. Investigation has found
that the engine cooling fan is constantly running at high speed and the following Diagnostic
Trouble Codes (DTCs) may be stored in the Powertrain Control Module (PCM):
• P2B61-73
• P26CB-72

https://www.odyssey.jlrint.com/odyssey/WorkflowHtmlComposition.do?wid=1584704442875
CAUSE:
The coolant diversion shroud inside the variable coolant pump is not moving to the correct
position when requested by the PCM. The PCM then activates the engine cooling fans at
high speed to avoid potential over heating. A new service part is now available.
ACTION:
Follow the instructions below.
