IGNITION COIL PRIMARY CIRCUIT
MALFUNCTION, (CYLINDERS 1-8)

G290076t1 : CHECK COIL FUNCTION BY SUBSTITUTION

1. Swap the suspect coil for a known good unit. 2. CLEAR the DTC. TEST the system for normal

operation.

Does the same DTC reoccur? The DTC will indicate if the same cylinder is misfiring.

-> Yes

INSTALL a new coil.

Ignition Coil-On-Plug (18.20.40) CLEAR the DTC. TEST the system for normal operation.

-> No

GO to Pinpoint Test G290076t2.

G290076t2 : CHECK THE IGNITION COIL SUPPLY VOLTAGE CIRCUIT

1. Disconnect the relevant ignition coil electrical connector(s), (PI02 to PI09). 2. Turn the ignition

switch to the ON position. 3. Make sure the ignition relay is energised. 4. Measure the voltage

between:

Cyl 1 PI02, pin 01 (RW) and GROUND.

Cyl 2 PI06, pin 01 (RW) and GROUND.

Cyl 3 PI03, pin 01 (RW) and GROUND.

Cyl 4 PI07, pin 01 (RW) and GROUND.

Cyl 5 PI04, pin 01 (RW) and GROUND.

Cyl 6 PI08, pin 01 (RW) and GROUND.

Cyl 7 PI05, pin 01 (RW) and GROUND.

Cyl 8 PI09, pin 01 (RW) and GROUND.

Is the voltage less than 10.5 Volts?

-> Yes

REPAIR the relevant ignition coil supply voltage circuit. This circuit includes the ignition relay, and the

front power distribution box (fuse 1). For additional information, refer to the wiring diagrams. CLEAR

the DTCs. TEST the system for normal operation.

-> No

GO to Pinpoint Test G290076t3.

G290076t3 : CHECK THE IGNITION COIL GROUND CIRCUIT

1. Turn the ignition switch to the OFF position. 2. Disconnect the relevant ignition coil electrical

connector(s), (PI02 to PI09). 3. Measure the resistance between:

Cyl 1 PI02, pin 03 (B) and GROUND.

Cyl 2 PI06, pin 03 (B) and GROUND.

Cyl 3 PI03, pin 03 (B) and GROUND.

Cyl 4 PI07, pin 03 (B) and GROUND.

Cyl 5 PI04, pin 03 (B) and GROUND.

Cyl 6 PI08, pin 03 (B) and GROUND.

Cyl 7 PI05, pin 03 (B) and GROUND.

Cyl 8 PI09, pin 03 (B) and GROUND.

Is the resistance greater than 5 ohms?

-> Yes

REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the

DTCs. TEST the system for normal operation.

-> No

GO to Pinpoint Test G290076t4.

G290076t4 : CHECK THE IGNITION COIL SWITCHING CIRCUITS FOR HIGH
RESISTANCE

1. Disconnect the battery negative terminal. 2. Disconnect the ECM electrical connector, PI01. 3.

Disconnect the relevant ignition coil electrical connector(s), (PI02 to PI09). 4. Measure the resistance

between:

Cyl 1 PI02, pin 04 (GU) and PI01, pin 87 (GU).

Cyl 2 PI06, pin 04 (GW) and PI01, pin 61 (GW).

Cyl 3 PI03, pin 04 (Y) and PI01, pin 88 (Y).

Cyl 4 PI07, pin 04 (GW) and PI01, pin 62 (GW).

Cyl 5 PI04, pin 04 (YR) and PI01, pin 89 (YR).
