Connect adapter 951 1351 ADAPTOR 86-PIN 951 1351 Adaptor 86-Pin to engine control module (ECM) connector and connect breakout box 981 3190 Replaced by 9511428 981 3190 Replaced by 951 1428 to adapter.





Will the engine control module (ECM) be connected when readings are taken on connector B?

Yes - Checking ground terminal #B28

No - Return to the fault-tracing procedure where it was interrupted.
No Fault Found

-------------------------------------------------

Checking ground terminal #B28




- Ignition off.
- Switch off all equipment that takes power from the battery (courtesy lighting, radio etc).
- Connect control module.
Connect an ohmmeter between #28 (#B28) on the breakout box and battery positive terminal.









The ohmmeter should read approximately 0 ohms for all readings.

OK - Return to the fault-tracing procedure where it was interrupted.
No Fault Found

Not OK - Checking for an open-circuit
