TIAGO

ELECTRICAL

INTRODUCTION

The electrical system of TIAGO is a

combination of electrical and electronic devices.

These are connected to each other electrically

through wiring harness and electronically through

high speed CAN (

Controller Area Network

).The

CAN gives reduction in complexity & weight of

Wiring harness & number of sensors. Many new

capabilities have been added due to the ability of

the controllers to communicate with each other.

The trouble shooting of TIAGO should

begin by reading errors logged by various

ECUS’/controllers using a diagnostic tester and by

confirmation that the controller no longer logs the

error. Every effort has been done in this manual

to simplify the troubleshooting of a vehicle of such

complexity as TIAGO.

Details of wiring harness, their routing and

electrical circuit schematics of different systems

are included in this Manual. These are only for

guidance during troubleshooting. However, due to

continuous improvements on the product, the

actual wiring layout, locations of components and

connectors, the wire colour codes etc. are likely to

be different on the vehicle which would be

informed to you from time to time.
