Foreword
The descriptions and service procedures contained in this manual are based on designs and methods studies carried out up to January 2010.
The products are under continuous development. Vehicles and components produced after the above date may therefore have different specifications and repair methods. When this is believed to have a significant bearing on this manual, supplementary service bulletins will be issued to cover the changes.
The new edition of this manual will update the changes.
In service procedures where the title incorporates an operation number, this is a reference to an V.S.T. (Volvo Standard Times).
Service procedures which do not include an operation number in the title are for general information and no reference is made to an V.S.T.
Each section of this manual contains specific safety information and warnings which must be reviewed before performing any procedure. If a printed copy of a procedure is made, be sure to also make a printed copy of the safety information and warnings that relate to that procedure. The following levels of observations, cautions and warnings are used in this Service Documentation:
Note: Indicates a procedure, practice, or condition that must be followed in order to have the vehicle or component function in the manner intended.
Caution: Indicates an unsafe practice where damage to the product could occur.
Warning: Indicates an unsafe practice where personal injury or severe damage to the product could occur.
Danger: Indicates an unsafe practice where serious personal injury or death could occur.

Design and Function
MID 140 Instrument Control Unit
The “Premium Tech Tool” (PTT) is the preferred tool for performing diagnostic work. Contact your local dealer for more information or visit “www.premiumtechtool.com”.
System Overview
The instrument cluster is used to provide the operator with information via gauges, indicator lamps and a display.
Via the three connectors on the rear of the instrument cluster module, information from the whole vehicle is received.
Some information is received from sensors directly connected to the instrument panel, and some is received across the J1587 data link. The data link permits other control units in the vehicle to send messages to the instrument panel. The instrument panel receives these messages, processes them and then presents the information in a suitable form to the operator.
The operator can use a control stalk on the steering column to cycle through a set of menus to gain a more detailed picture of the vehicle status.
For more information about the control stalk, refer to either the “General Electrical Manual” found in function group 30 or the truck Operator’s Manual.

The “Premium Tech Tool” (PTT) is the preferred tool for performing diagnostic work. Contact your local dealer for more information or visit “www.premiumtechtool.com”.
The control units on the information link communicate according to the SAE J1587 standard. The standard has been extended with Volvo’s own supplement (PPID, PSID). The fault codes set by the control units contain information that is described by the following abbreviations.
