DISPLAYING DIAGNOSTIC TROUBLE CODES

The ability to display diagnostic trouble codes (DTC) is an optional feature. Codes may be displayed on either the gauge cluster or an optional vehicle information display (VID). The vehicle must be equipped with the option to display codes in both cases. Codes will not be displayed on the gauge cluster if the vehicle is equipped with the VID.

VEHICLES EQUIPPED WITH OPTION TO DISPLAY CODES

Displaying Codes on the Gauge Cluster (Non-VID equipped vehicles)

To display codes on vehicles not equipped with a VID:

1. Set the parking brake.

2. Turn the key switch to the ACCESSORY position to view only previously active codes. Turn the key switch to the IGNITION position to view both active and previously active codes.

3. Momentarily press the Cruise "ON" switch and the Cruise "Resume" switch at the same time.

A gauge sweep will be performed on the gauges. The gauge cluster will then display the following information for 5 seconds:

• Software Rev: XXX

• Hardware Rev: XXX

• Active Faults: XXX

• Total Faults: XXX

If faults are present, the gauge cluster display will show each diagnostic trouble code for 10 seconds and then automatically scroll to the next entry and continue to cycle through the faults. Once all faults have been displayed the number of faults will be displayed again, then the cycle will repeat. To manually cycle through the fault list press and release the cluster display selector button. The following information will be displayed for each fault:

SPN: XXXX FMI: XX

Active

OC: XXX SA: XXX

SPN: XXXX FMI: XX

Previously Active

OC: XXX SA: XXX

Displaying Codes on the VID (if equipped)

The VID can be used to display all diagnostic trouble codes (DTC) on the vehicle. Suspect parameter number

(SPN), failure mode indicator (FMI) and occurrence count numbers are listed. Source addresses and DTC

descriptions are presented in plain text.

NOTE – The VID will display “Not Available” if a DTC description is not available for a particular fault.

Displaying codes will only be allowed if all of the following conditions are true:

• The key switch is in the IGNITION position.

• AND displaying codes is allowed due to vehicle orderable options

• AND the programmable parameter “Diagnostics” is enabled using Diamond Logic® Builder (DLB).

• The vehicle is not moving (the Vehicle Speed is equal to zero).

• The feature is not password protected to prevent unauthorized access. Refer to the Vehicle Information

Display Owner’s Manual for more information.

Perform the following steps if all of the above conditions are met:

1. Go to the main menu screen

NOTE – The following selections will not be available if the vehicle is not equipped with the option to

display codes.

2. Select “DIAGNOSTIC CODES”

3. Select “ACTIVE” or “INACTIVE”. The VID may initiate a password prompt if the VID has been password

protected. Refer to the Vehicle Information Display Owner’s Manual for more information.

The VID will indicate "NO FAULT DETECTED" if faults are not found. Scroll through the list of faults if faults

are present.

The following information will be displayed for each fault:

DTC Description

CLEARING DIAGNOSTIC TROUBLE CODES

Previously active diagnostic trouble codes can only be cleared by a service tool, such as Diamond Logic®

Builder (DLB). Some previously active codes may not be cleared by this method.

DEFINITIONS

• “SPN” represents the Suspect Parameter Number. This number identifies the item for which diagnostics

are being reported.

• “FMI” is the Failure Mode Indicator. This number represents the type of failure detected. Refer to Failure

Mode Indicators (FMI) below for more information.

“Active” or “Previously Active” will be displayed to identify whether a fault is currently active or if the fault

was previously active.

• “OC” is the Occurrence Count. This number represents the number of times a fault has gone from

previously active to active.

• “SA” is the Source Address. This number identifies the module reporting the fault. Refer to Source

Addresses (SA) for more information.

• FMI=0 - Data Valid But Above Normal Operational Range - Most Severe Level

• FMI=1 - Data Valid But Below Normal Operational Range - Most Severe Level

• FMI=2 - Data Erratic, Intermittent Or Incorrect

• FMI=3 - Voltage Above Normal, Or Shorted To High Source

• FMI=4 - Voltage Below Normal, Or Shorted To Low Source

• FMI=5 - Current Below Normal Or Open Circuit

• FMI=6 - Current Above Normal Or Grounded Circuit

• FMI=7 - Mechanical System Not Responding Or Out Of Adjustment

• FMI=8 - Abnormal Frequency Or Pulse Width Or Period

• FMI=9 - Abnormal Update Rate

• FMI=10 - Abnormal Rate Of Change

• FMI=11 - Root Cause Not Known

• FMI=12 - Bad Intelligent Device Or Component

• FMI=13 - Out Of Calibration

• FMI=14 - Special Instructions

• FMI=15 - Data Valid But Above Normal Operating Range - Least Severe Level

• FMI=16 - Data Valid But Above Normal Operating Range - Moderately Severe Level

• FMI=17 - Data Valid But Below Normal Operating Range - Least Severe Level

• FMI=18 - Data Valid But Below Normal Operating Range - Moderately Severe Level

• FMI=19 - Received Network Data In Error

• FMI=20 - Data Drifted High

• FMI=21 - Data Drifted Low

• FMI=31 - Condition Exists
