M4/7 (Engine and AC electric suction fan with integrated control) : Output stage
Test 1: Check component M4/7 (Engine and AC electric suction fan with integrated control).
Test 2: Possible cause:
- Heat management
Affected functions:
- Engine cooling
1. Check component M4/7 (Engine and AC electric suction fan with integrated control).
Test 1.1: Check component M4/7 (Engine and AC electric suction fan with integrated control) by means of actuation.
Test 1.2: Test PWM signal for operating the suction fan.
1.1. Check component M4/7 (Engine and AC electric suction fan with integrated control) by means of actuation.
Check component M4/7 (Engine and AC electric suction fan with integrated control) by means of actuation.
Test prerequisite
- Coolant temperature< 80锟斤拷 C
- Charger connected(The battery voltage must be higher than 12.5 V.)
- Ignition ON
- Engine not running
- Vehicle stationary
- Fuse F32f71 (Fuse 71) is OK.
Actual value:
- Coolant temperature:Warning! Communication with ECU required.
Specified value
- Coolant temperature< 80锟斤拷 C
Proceed to 'Actuation' with F2
1.2. Test PWM signal for operating the suction fan.
Check power supply of component M4/7 (Engine and AC electric suction fan with integrated control).
Test prerequisite
- The ignition must be switched on.
Test sequence
- Check power supply at connector of component M4/7 (Engine and AC electric suction fan with integrated control) (pin 2) against ground.
