[1] K40/4K3 (Air Pump Relay), N10/1KO (Air Pump Relay): Short Circuit to Positive

[1] K40/4k3 (Air pump relay), N10/1kO (Air pump relay): Short circuit to positive [P0410]

Check component N10/1kO (Air pump relay)

Test current consumption of component N10/1kO (Air pump relay)

Test sequence
- Switch off ignition.
- Connect socket box (35-pin) to component N3/10 (ME-SFI control module).
- Connect socket box (126-pin) to component N3/10 (ME-SFI control module).
- (5.5) 5<-->91 (4.6)
- Switch on ignition.

Note: Perform the measurement only for a short time so that component M33 (electric air pump) does not overheat.

Specified value
- Amperage [0.1...0.3] A
- Component M33 (electric air pump) is switched on and is heard to run.

Question: Is the measured value okay?

No
- The measured value is not o.k.
Possible cause and remedy
- Leads to component N10/1kO (Air pump relay)
- N10/1kO (Air pump relay)
**End of test**

Yes
- The measured value is o.k.
