Tester MS016

INTRODUCTION
The actual Operation Manual contains the description of a diagnostic process. The purpose is to
assess the technical condition of alternators and voltage regulators (separately from
alternators), and to read data transmitted via a LIN bus.
WARNING! The actual instruction does not provide a description of all the diagnostic aspects.
If you lack knowledge or experience, we recommend you to take training at the equipment
manufacturing facility.
The tester purpose is as follows:
1. Assessing performance of automotive alternators with a nominal voltage of 12/24V and
stop-start alternators with a nominal voltage of 12/24V (VALEO I-StARS). The diagnosis is carried
out either on a car or on the test bench that provides its drive and a load on the alternator.
2. Assessing performance of voltage regulators separately from alternators.
3. Reading and saving data transmitted via the LIN bus of a vehicle («LIN analyzer» function).
4. Diagnosing starters directly on cars without their removal or on the test bench that provides
proper unit fixation and power supply using cable MS-33503.
WARNING! Cable MS-33503 is not included in the equipment set and can be purchased
separately.
Below are the criteria for alternator and voltage regulator performance assessment:
- stabilizing voltage;
- control lamp operation;
- FR (displayed FR signal frequency and waveform, voltage regulator feedback).
For COM voltage regulators:
- ID;
- Protocol type;
- Data exchange rate;
- LIN protocol type;
- Voltage regulator self diagnosis faults.
