AR54.10-P-1030-05I Establish Fused Components With Excessive Quiescent Current Consumption Fuse Assignment, As-built Configuration

Relay assignment, production details

Special Tools:

Commercially Available Tools:

1. Determine possible standby current consumers on the problem fuses.
Refer to assignment and cable connections of fuse blocks, insertion sheet or "Wiring Diagrams Model 215/220/230".
Obtain the location of components from the 215, 220, 230" or STAR diagnosis.

2. Unplug connector at the possible quiescent current consumer.
3. Read the standby current on the second multimeter.

If measurements are to be made at the radio fuse or if the radio coupling is disconnected, it must be observed that the quiescent current consumption rises by approx. 0.240 A (240 mA) when the radio is reconnected. By switching the radio on and o the standby current draw is raised.

On vehicles with navigation system after inserting the navigation computer fuse an increased quiescent current of approx. 800 mA occurs for the duration of the computer run-up (approx. 20 minutes). This also applies when the coupling is separated from the computer and connected again.

Standby current >0,020 A (20 mA):
Quiescent current error remains after disconnecting the connector. Component is okay, fit connector in again at the component tested.

4. Carry out checking as described with all components at the fuse about which there has been a complaint.

Standby current ≤ 0,020 A (20 mA):
Quiescent current error is rectified after disconnecting the connector of the relevant component. Component is defective, replace: (Down-arrow)

5. To be sure check the total standby current again.
