with air conditioning,
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (start the
engine
+ 5 seconds, then switch off the ignition and wait for 1 minute).
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
Check the coolant temperature sensor connections.
