3 How to read wiring diagrams - Relay location number Indicates location on relay panel. - Arw Indicates wiring circuit is continued on the previous and/or next page. 3 - Connection designation - relay contl module on relay panel Shows the individual terminals in a multi-point connector. For example: contact 4 on terminal 4 on relay panel. 4 - Diagram of threaded pin on relay panel White circle shows a detachable connection. 5 - Fuse designation For example: S8 = Fuse number 8, 5 amps, in fuse holder 6 - Reference of wire continuation (current track number) Number in frame indicates current track where wire is continued. 7 - Wire connection designation in wiring harness Location of wire connections are indicated in the legend. 8 - Terminal designation Designation which appears on actual component and/or terminal number of a multi-point connector. 9 - Gund connection designation in wire harness Locations of gund connections are indicated in legend. 0 - Component designation Use legend at bottom of page to identify the component code. - Component symbols (see page IV - VI) - Wire css-section size (in mm )andwirecolors Abbreviations are explaining in color chart beside the wiring diagram. 3 - Component symbol with open drawing side Indicated component is continued on another wiring diagram. The number of corresponding wiring diagram can taken fm list of contents. 4 - Internal connections (thin lines) These connections are not wires. Internal connections are current carrying and are listed to allow tracing of current flow inside components and wiring harness. 5 - Reference of continuation of wire to component For example: Contl module for anti-theft immobilizer J36 on 6-Pin Connector, terminal 6 - Relay panel connectors Shows wiring of multi-point or single connectors on relay panel For example: S3/3 - ulti-point connector S3, terminal Reference of internal connection continuation Letters indicate where connection continues on the previous and/or next page.

7 Explanation of tubleshooting pcedures Starting with the reported pblem, tubleshooting pcedures show step-by-step what is checked and how it is checked in order to find the pblem in the quickest and most reliable way. If several causes (of a pblem) are possible in one system, a test pcedure is used for diagnosis. Structure of a Test step: What is checked (assumed pblem) How is it checked Test results Cause of pblem/repair instructions To next test Example of a tubleshooting pcedure: Open circuit in relay panel between connector terminals A4 and D - Connect terminal D of multi-point connector to gund using Connector Test Kit VW 594 Warning lamp lights Warning lamp does not light Replace relay panel To next test Explanation of tubleshooting pcedures VII
