Step | Action | System Response | Notes / Comments |
I | To obtain stored fault codes, the following procedure must be followed: Open ECU to expose to expose the multicoloured plug/wiring, and identify the black diagnostic plug (bottom right corner - plug has short jumper cable installed). Switch Ignition ON (ECU powered). Wait for at least 1 second, Then pullout the black plug | | The ECU incorporates a blink code system, using a built-in diagnostic plug and LED. |
II | No stored faults in ECU: | The LED (below the black diagnostic plug) will immediately flash the configuration code | See the Blink Code List (and above diagram) for how to interpret the ABS Indicator Lamp flashes. |
III | Stored faults present in ECU: | A series of 10 rapid flashes of the LED (below the black diagnostic plug) will be displayed. | See the Blink Code List (and above diagram) for how to interpret the ABS Indicator Lamp flashes. |
| To access any stored faults, replace the black diagnostic plug for at least 1 second and then remove it. | The first blink code displayed on the LED (after approx. 1 second) is the configuration code, | |
| To display the first fault code (the most recent fault detected), replace the black diagnostic plug a further time for at least 1 second, and then remove it. | The Blink Code is in two parts - 'tens' and 'units'. The flashes for the 'tens' are of longer duration than those for the 'units' (see above diagram). | |
| To display the next fault, replace the plug for at least 1 second, and then remove it again. This process is repeated until all the faults have been displayed. | When all stored faults have been displayed, this is indicated by a a series of 10 rapid flashes on the LED. | |
III | Count the flashes from the ABS Indicator Lamp. Write down only the first 4 or 5 Blink Codes for faults recorded on the ECU (there may be several stored in the memory). | The first code displayed is for the configuration of the system (see above diagram), following which faults are shown as Blink Codes. | |
IV | Turn Ignition OFF Determine if faults recorded in III above are active or stored: | | Active Faults: Will reappear (repeat) after any Blink Codes have been deleted from the ECU. Stored Faults: Will be cleared when Blink Codes are deleted from ECU. NOTE: Last fault stored is first fault displayed. |
V | Clearing ECU fault memory: Repeat steps I to III above. When all faults in the ECU memory have finished (indicated by a series of 10 rapid flashes), insert the black diagnostic plug during this series of flashes. | The fault codes will now be deleted providing there are no active faults still present. The ECU self-configures after the memory has been cleared. The ECU self-configures to the status of the system at the time of ‘powering up’ and so any component connected after configuration has taken place will not be recognised by the ECU. | |
VI | Turn Ignition OFF | | |
VII | Repeat steps I to III above. Record Faults (Blink Codes). | Only active faults will be shown now. | To identify blink codes, refer to the Blink Code List. Make the necessary repairs to active faults. Repeat Step V (Clearing ECU fault memory), then road test the vehicle. The warning light should go out. If the warning light remains after road testing, go back and repeat steps II , III and VII again until the warning light does go out. Record faults for future reference |
