Holden Fault Codes

System Malfunctions fall into Two Categories.

 

1. Hard Faults

 

Indicated by the MIL being illuminated whenever the Engine is running.

 

2. Intermittent Faults.

 

Cause the MIL to be illuminated while the Fault is present.

The MIL will go out approximately Ten Seconds after the Fault disappears.

 

Faults of Either Type will cause a Fault Code to be stored in Memory.

 

Some Fault Codes do NOT illuminate the MIL.

(Indicated in the Fault Code Table)

 

All Fault Codes consist of Two Digits.

If NO Fault Codes are stored in Memory:

A Code 12 will be displayed.

 

This consists of;

One Flash of the MIL.

Followed by a 1.2 Second Pause.

Two Flashes of the MIL.

Followed by a Longer Pause.

 

The Code is then repeated.

If more than One Fault Code is stored in Memory:

The Code with the Lowest Numerical Value will be displayed Three Times.

 

The Code with the Next Higher Numerical Value will be displayed Three Times.

 

Fault Code Extraction To enter Diagnostic Mode:

 

Join Terminal 5 and Terminal 6 on the Diagnostic Connector.

Turn the Ignition Switch ON.

The Fault Codes will be displayed on the MIL.
