Electrical Test

Notes:
- We digital md1timeter Fluke 83 (US 1119) for tests.
- The specified values stated apply to an ambient temperature of 10°...40°C (50°...104°F)
- If the readouts obtained differ from the specified values, determine the malfunction via the wiring diagram.
- If the readouts obtained differ only slightly from the specified values, clean the contacts and connectors of the testers and test wiring and repeat the test. Before replacing a particular component, test the wiring and connections and repeat the resistance measurement at component, particularly in the case of specified values of less than 10.
- Use test box VAG 1598 with the adapter cable VAG 1598120 for connecting the testers.
- The contact numbers of the connector and the socket numbers of the test box VAG 1598 are identical.

CAUTION!
Set the relevant measuring range at the tester before connecting the test cables to avoid damaging any electronic components.

Test requirements:
- Battery voltage in order.
- Fuses 3, 15 and 31 for transmission control module in order
- Fuses of the component being tested in order.
- The fuse holder is located behind a cover in the side of the instrument panel.
- Ground connections OK.
- Check Battery Ground strap and Ground strap between body and transmission.

Note:
Switch ignition off for all test steps.
- Separate multi-pin connector from Transmission Control Module -J217- (control module is located in front of right front seat below carpeting in foot well).
- Connect test box VAG 1598 with adapter VAG 1598/20 to harness connector.

Note:
- If the readings obtained differ from the specifications, perform the measures stated in the right-hand column of the test table.
- Perform all the measures stated in the column "Corrective steps".
- Perform only the test steps recommended in the DTC table (specific testing).
