2. CUSTOMER PROBLEM ANALYSIS

   
   

   1. Ask the customer about the problems and the conditions at the time the malfunction occurred to make sure the problem symptom was not temporarily caused by radio waves in the surrounding environment.

      Tech Tips

      The parking assist monitor display may be temporarily distorted due to radio waves around the vehicle.

      *: DTCs output as "Hist" will not be output again after DTCs are cleared.

      Problem Symptom	Cause
      Both of the following conditions are met: The problem symptom indicates a parking assist monitor display malfunction and the problem symptom cannot be reproduced. DTC C1622 is output as "Hist" only.*	The display may be temporarily distorted when the vehicle is close to an object that transmits radio waves, such as a telecommunication tower, an airport or a truck equipped with a transceiver.

      *: DTCs output as "Hist" will not be output again after DTCs are cleared.
