Multimeter V.A.G 1526A






Test box V.A.G 1598/21


Note:
- For testing, use Multimeter V.A.G. 1526 A or VAS 5051 Vehicle Diagnosis, Measurement and Information System. The charts contain the specific measurement methods which have to be set up before the corresponding measurements.
- The specified values given are valid for an ambient temperature of 0°C to 40°C.
- If the values measured deviate from the specified values, determine the malfunction using the wiring diagram.
- If the values measured show only a minor deviation from the specified values, clean cavities and plugs on the test equipment and test leads, repeat test. Before replacing the components in question, check their wires and connectors. In particular with specified values below 10 Ohms repeat the resistance measurement on the component.
- The terminal numbers of the connector and the cavity numbers on the V.A.G. 1598/21 test box match.

CAUTION! In order to avoid destroying electronic components, the specific measurement range on the measuring equipment must be switched on before connecting the test leads.
