A. HAND-HELD TESTER (HHT) MODULE PLANNING OVERVIEW

Periodic updates to HHT Modules and the introduction of new HHT Modules ensure that the dealer technician is provided with the very latest diagnostic information concurrent to production changes and the introduction of new modules. Therefore, it is very important to use the latest HHT Module available when performing diagnosis. The following table provides an overview of HHT Module planning.

MODULE PLANNING OVERVIEW

Issue	Model Application	Comment
1/94	124, 129	Obsolete (replaced by 12/94 issue, see below)
3/94	140	Obsolete (replaced by 12/94 issue, see below)
6/94	202	Obsolete (replaced by 12/94 issue, see below)
12/94	124, 129, 140, 202	New Issue (replaced for 1/94, 3/94, 6/94 issues)

IMPORTANT: Obsolete module 1/94, 3/94 and 6/94 are NOT to be returned at this time. Please store these modules with the new module in the HHT carrying case. Do not discard these obsolete modules as you will forfeit their core charge ($ 400.00 ea.)! Dealer will be informed as to handling procedures regarding these modules in the future.

For further details regarding the HHT Module Program Update Service, please refer to S.I. MBNA 58/77A , 99/162A. January 1995.

B. INTRODUCTION OF 4 MBYTE MODULE

The release of the 12/94 HHT module marks the introduction of a 4 MByte module which provides diagnostic coverage for all models including models 124, 129, 140 and 202. The integration of the three previously valid modules into one module will allow the user to quickly determine the status of modules on hand and will allow for easier updating, currently planned to take place approx. 4 times per year.

The past, often confusing practice of including updated diagnostic information for a particular model on a module labeled for use only with a different model should no longer occur.

The timeliness of future module updates is also scheduled for improvement with the decision to perform the update service locally at the Customer Assistance Center (CAC) in Montvale. New Jersey. Further details regarding revisions to the update service will be released at the modules next update.
