[NOTES

information on preventing damage to electronic components due to electrostatic discharge
- The safety information and descriptions listed in Help (FS) MUST be observed. A

General test conditions

- Use only cable with fuse for bridges.

- Each time after replacing a component, always carry out a component test.

-A.component test should be carried out in order to ensure the correct connection of separated plug connections (electric or pneumatic).
When processing a fauit code, a fault code may be generated by a test step which is interrogated in a YESINO cell

- This step may temporarily result in other fault codes which should be ignored.

- Only generate counterfauit by short circuit and open circuit if this is expressly requested in the decision tree.

Safety note
- Pay attention to the safety notice ‘AS 58.40-Z-0001-01A' on the use of the diagnostic units in mobile applications.

(General information

- The data read out of the control units refer to specific events or system statuses and serve as a basis for narrowing down the source of the defect. The
data may include a tolerance and it may therefore not necessarily be possible to link them to a certain event, location or time.
