Testing quiescent current - AR54.10-P-1030-03CS

Fig 1: Identifying Electrical Connection Set (201 589 00 99 00)

Observe limit value of multimeter for voltage measurements. A current of approx. 20 A  flows when the central locking starts operating.

Do not activate any other consumers during the test, otherwise observe new after-run time of approx. 4 minutes.

1. Connect multimeter to negative terminal and positive terminal of battery.
2. Lock vehicle and wait for approx. 4 minutes (after-run time for electronic components). ↓

   Display  ≤0.05 A  (≤0.085 A  on vehicles with immobilizer) = specified value achieved: ↓

   Carry out work step 3.

   Display  ≥0.05 A  (≥0.085 A  on vehicles with immobilizer): ↓

   Carry out work step  4.

3. Unlock vehicle and wait for approx. 4 minutes (after-run time for electronic components). ↓

   Display  ≤ 0.05 A  (≤0.085 A  on vehicles with immobilizer) = specified value achieved: ↓

   End of test.

   Display  ≥0.05 A  (≥0.085 A  on vehicles with immobilizer): ↓

   Carry out work step  5.

4. Unlock vehicle and wait for approx. 4 minutes (after-run time for electronic components). ↓

   Display  ≤0.05 A  (≤0.085 A  on vehicles with immobilizer): ↓

   Note displayed value. Determine circuit with higher quiescent current.

   Display  ≥0.05 A  (≥0.085 A  on vehicles with immobilizer): ↓

   Carry out work step 5.

5. Open trunk lid. Operate microswitch on trunk lock and wait for approx. 4 minutes (after-run time for electronic components). ↓

   Display  ≤0.05 A  (≤0.085 A  on vehicles with immobilizer: ↓

   Adjust switch (trunk illumination) on trunk lock, replace if necessary and carry out work step  2 again to check.

   Display  ≥0.05 A  (≥0.085 A  on vehicles with immobilizer): ↓

   Note displayed value. Determine circuit with higher quiescent current.
