Test readings, control module connections


Test readings and instructions for measuring voltage levels on the SID unit are given on the following pages.

Remember:


Unless otherwise stated, all voltage measurements should be carried out with all components connected and with the ignition switch in the Drive position.

Readings should be taken with a Breakout box (BOB) connected between the SID unit and its connector.

Several voltage levels should be regarded as guiding values. Use your common sense when judging whether a particular reading is correct or not.

If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
