Check Component Y2/1 (Supercharger Magnetic Clutch)

Test 1 Check Actual Value Y2/1 (Supercharger Magnetic Clutch)
Test 2 Current Consumption of Component Y2/1 (Supercharger Magnetic Clutch)
Test 3 Test Internal Resistance of Component Y2/1 (Supercharger Magnetic Clutch)


1 Check Actual Value Y2/1 (Supercharger Magnetic Clutch)

Test requirement
- Engine running
- Engine speed > 2900 rpm
- Engine load > 44 %
- Selector lever position D

Actual values :
- Temperature of coolant: Note! Communication with ECU required
- Engine load: Note! Communication with ECU required

Status of relevant actual value:
- Y2/1 (Supercharger magnetic clutch):

Specified value
- Y2/1 (Supercharger magnetic clutch):CLOSED

Question
- Is the actual value o.k.?
Yes
The actual value is okay.
Note
- If stored faults present with high fault frequency counter or if customer complaints exist, inspect cables and plug connections for loose contact and corrosion.
No
An actual value is not o.k.
Possible cause and remedy
- Test current consumption of component Y2/1 (Supercharger magnetic clutch).
- Test internal resistance of component Y2/1 (Supercharger magnetic clutch).

** End of Test **


2 Current Consumption of Component Y2/1 (Supercharger Magnetic Clutch)

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).
- (1.1) Pin 1 of 126 <--> Pin 5 of 35 (5.5)
- Switch on ignition.

Specified values
- Amperage 2 .. 3.5 A

Note
- Component Y2/1 (Supercharger magnetic clutch) is heard to operate.

Question
- Is the measured value okay?
Yes
The actual value is okay.
Note
- If stored faults present with high fault frequency counter or if customer complaints exist, inspect cables and plug connections for loose contact and corrosion.
No
The measured value is not o.k.
Possible cause and remedy
- Test internal resistance of component Y2/1 (Supercharger magnetic clutch).
- Test cable from control module N3/10 (ME-SFI control module) (connector 1, pin 1) to component Y2/1 (Supercharger magnetic clutch).
- Cable between component Y2/1 (Supercharger magnetic clutch) and component K40
- Voltage supply K40

** End of Test **
