Pinpoint Tests

CAUTION: When probing connectors to take measurements in the course of the pinpoint

tests, use the adaptor kit, part number 3548-1358-00.

NOTE:

When performing electrical voltage or resistance tests, always use a digital multimeter (DMM)

accurate to 3 decimal places, and with an up-to-date calibration certificate. When testing

resistance, always take the resistance of the DMM leads into account.

Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

INJECTOR CIRCUITS (VEHICLES
WITHOUT SUPERCHARGER)

G240048t1 : CHECK THE INJECTOR COIL RESISTANCE

1. Disconnect the relevant injector electrical connector:

Injector connector

Cylinder 1, PI32

Cylinder 2, PI36

Cylinder 3, PI33

Cylinder 4, PI37

Cylinder 5, PI34

Cylinder 6, PI38

Cylinder 7, PI35

Cylinder 8, PI39

2. Measure the resistance between the injector pins.

Is the resistance between 12 and 16 ohms?

-> Yes

GO to Pinpoint Test G240048t2.

-> No

INSTALL a new injector.

Fuel Injectors (18.10.02) CLEAR the DTC and test the system for normal operation.
