CONNECTING THE BREAKOUT BOX, ENGINE CONTROL MODULE (ECM)

Special tools:

Special Tool: 951 3052 ECU Adapter

Special Tool: 951 1428 Breakout box

Special Tool: 951 1499 Cable

CAUTION:

Avoid touching control module connector pins and associated cable harness connectors. There is risk of electrostatic discharge, which could cause damage in the control module. Discharge yourself and the tools to be used by holding the metal part of the tool and at the same time touch a part of the body immediately before starting to work.

GENERAL INFORMATION

Visually check the connectors to ensure that the male and female terminals are not damaged and that the cables for the female halves are properly connected.

The breakout box is designed for easier reading of:

control module's output and input signals when the control module is connected.
leads' and components' resistance, when the control module is disconnected.

Using the breakout box reduces the risk of short-circuiting leads and damaging pins in the connectors.

CONTROL MODULE DISCONNECTION

Wait 3 minutes after switching off the ignition before starting work on the control module. The system relay must be voltage free before the control module can be removed from the vehicle. If the engine cooling fan runs on after the ignition has been switched off, wait until it stops and then wait for a further 3 minutes.
