1 SPECIAL INSTRUCTION Reference: SI E0920 June 17, 2009 Attention: This notice is being issued to advise you of new information for certain Caterpillar ( CAT ) Telehandlers that were manufactured by JLG Industries, Inc. ( JLG ). TITLE: Diagnostic Code Information for Transmission and/or Engine control systems used on certain CAT Branded Telehandlers. APPLICABLE PRODUCTS: Model TH336 TH337 TH406 TH407 TH414 TH514 TH417 Serial Number Range TDE00100 & After TDF00100 & After TBX00100 & After TBY00100 & After TBZ00100 & After TBW00100 & After TBT00100 & After INTRODUCTION: The diagnostic code information that follows is utilized by certain CAT Branded Telehandlers that are equipped with Caterpillar electronic controls. Component identifiers, failure mode identifiers, and module identifiers are pieces of information that assist service personnel in diagnosing system problems of the machine. A component identifier (CID) is a diagnostic code that informs the service personnel of the specific circuit or system within which a problem was detected. A failure mode identifier (FMI) is a diagnostic code that informs the service personnel of the type of problem that has been detected within a circuit or system. Event codes identify significant events that occur to the systems of the machine. The ECM stores the data from the events. This function allows tracking of the history of the machine. The data is used as an aid for managers and maintenance personnel. Page 1 of 7

2 TRANSMISSION RELATED DIAGNOSTICS Details are following for the transmission control system related diagnostics that are supported by the system. This system will support diagnostic reporting in SAE J1939 SPN-FMI format only.
