HOW TO UPDATE EMISSION TSB's

This is the first update of 1984 model year engine/emission calibrations, originally issued in TSB 83-19A on Sept. 20, 1983. This TSB update contains the following:
^ A new Index
^ 22 new or updated passenger car calibrations
^ 79 new or updated truck calibrations
^ 3 new or updated diesel calibrations

The first issue of the engine/emissions TSB was divided into four sections, (transmissions, passenger car calibrations, truck calibrations, and diesel calibrations) with each page marked by section and page number. This update and also future updates are simply a continuation of the first TSB with the page numbers continuing from where they left off. For example, car calibrations in TSB 83-19A ended on page 3-55. Car calibrations in this update start with page 3-56.

The key to finding a calibration in this or any future update of the TSB's will be the INDEX. Upon receiving this update, discard the index in TSB 83-19A and insert the new index in front of TSB 83-19A. Place the remaining part of the package behind TSB 83-19A. Anytime information is needed, refer to the newer index for the required page number.


MORE THAN ONE VECI DECAL MAY EXIST FOR EACH CALIBRATION. BEFORE ORDERING A DECAL, CONTACT YOUR DISTRICT OFFICE FOR THE CORRECT DECAL NUMBER THAT MATCHES THE VEHICLE AND CALIBRATION YOU ARE WORKING ON.
