DTC Index

NOTE:

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5

digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last

2 digits give extra information read by the manufacturer-approved diagnostic system).

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.

PINPOINT TEST G531326p1 : IGNITION
COIL CIRCUITS

G531326t2 : CHECK THE IGNITION COIL SUPPLY VOLTAGE CIRCUIT

1. Disconnect the relevant ignition coil electrical connector:

Ignition coil connector

Cylinder 1, PI02

Cylinder 2, PI06

Cylinder 3, PI03

Cylinder 4, PI07

Cylinder 5, PI04

Cylinder 6, PI08

2. Key on, engine off. 3. Make sure the ignition relay is energized. 4. Measure the voltage between:

Ignition coil connector, harness side

Battery

Pin 01

Negative terminal

Is the voltage less than 10.5 Volts?

-> Yes

REPAIR the relevant ignition coil supply circuit. This circuit includes fuse 15 of the front power

distribution box and the ignition relay. For additional information, refer to the wiring diagrams.

CLEAR the DTCs and test the system for normal operation.

-> No

GO to Pinpoint Test G531326t4.
