FAULT FINDING - INTRODUCTION

PRECAUTION

When carrying out checks using a multimeter, avoid using a contact point on the connectors the size of whichcould damage the clips and result in poor contact.

For all checks and measurements carried out on the 30-way connector of certain instrument panels, alwaysuse bornier Elé. 1302.

Bornier Elé. 1302 enables:

- continuities to be checked. To do this, simply connect the bornier to the 30-way instrument panel connec-tor or to the connector at the vehicle wiring end,

- voltages or frequencies to be measured, frequencies to be generated, etc... To do this, connect the bornierin series between the instrument panel unit and the connector at the vehicle wiring end.
