Caution:
The California Air Resources Board (CARB) will be performing an audit of vehicles serviced for this recall.
Failure to perform all steps of the recall service procedure completely and accurately may cause emissions noncompliance. Further, CARB considers
failure to properly perform emissions recall procedures to be a violation which may subject the servicing dealer to a significant fine.
Details of this service action are explained in the following sections. As an additional service aid, a videotape demonstrating the service procedure is
included in the June, 1990 Master Tech program.

Each California Dodge or Chrysler-Plymouth dealer without a Vehicle List will receive an information copy of this letter by Compak Mail for use in
performing the service on involved vehicles upon request.
