The fuel pump has a short circuit to ground.
Test 1: Check component Fuel pump.
Test 2: Possible cause:
- M3 (Fuel pump)
Affected functions:
- Engine diagnosis
- Fuel system
1. Check component Fuel pump.
Test 1.1: Check power consumption of component M3 (Fuel pump) using multimeter.
Test 1.2: Check internal resistance of component M3 (Fuel pump).
Test 1.3: Test the cables from component N118 (Fuel pump control module) to component M3 (Fuel pump) with the plug connection M3x1 (Fuel
pump connector) between the two.
1.1. Check power consumption of component M3 (Fuel pump) using multimeter.
Test prerequisite
- A fault has occurred during current measurement at component M3 (Fuel pump).
Test sequence
- Switch on ignition.
- Unplug 4-pin connector from control module N118 (Fuel pump control module).
- Bridge pin 2 in pin 4 at the unplugged connection of component N118 (Fuel pump control module).
- Measure current.
- Measure direct current with multimeter between sockets (N118) 1.1 and (N118) 1.3
Notes
- Socket (N118) 1.1 : Voltage supply of component N118 (Fuel pump control module): Positive
- Socket (N118) 1.2 : Voltage supply of component N118 (Fuel pump control module): Minus
- Socket (N118) 1.3 : Voltage supply to component M3 (Fuel pump): Positive
- Socket (N118) 1.4 : Voltage supply to component M3 (Fuel pump): Minus
Specified values
- Current: [10.0 ... 15.0] A
Question
- Is the measurement value OK?
