Test Equipment

In addition to a standard volt/ohm meter, jumper wires and connectors, some special testing equipment and BMW-specific procedures are REQUIRED for proper diagnosis of the Motronic system. The "BMW Service Test Kit", Bosch L-Jetronic Fuel Injection Testing Procedures Brochure, and BMW Test Meter (12 6 400, 13 1 092, 13 1 094 and 22 13 100) are REQUIRED to properly test Motronic systems. This equipment will be referred to throughout the following test procedures and MUST be used as indicated. Failure to do so may result in unnecessary replacement of good component parts. The information in this article will guide you, but without the BMW-specific tools, only basic tests can be performed.
