Step | Action | System Response | Notes / Comments |
I | Connect a switch (Diagnostic Push Button) between the Diagnostic Line 'L' (Pin 14 of the ECU) and Ground. | Blink Code display (i.e. a sequence of flashes) may be initiated. The Blink Code will be displayed on either the Dashboard ABS Warning Lamp (INA) or the Traction Control Warning Lamp (ASR). Consult the Vehicle Manufacturer’s Handbook to establish which lamp is used and where it is located. | In the absence of the Vehicle Manufacturer’s Handbook, a bulb with a maximum power of 10 W can be connected between Ground and the ASR lamp pin of the ECU (Pin 3) (see appropriate wiring diagram). |
II | Switch Ignition ON (ECU powered). Wait at least 2 seconds, Then press Diagnostic Push Button for approximately 2 seconds, Then release button. | The ABS Indicator Lamp will illuminate whilst the button is pressed, and go out when it is released. | The Blink Codes are displayed in blocks of flashes of the lamp. Subsequent pressing of the Diagnostic Push Button to that described in Column 2 of this row (Step II), will display only one Blink Code. Further Blink Codes can be displayed by additional activation / pressing of the Diagnostic Push Button. The Blink Code for the most recently detected fault is displayed first. When all stored faults have been displayed, the first fault code will be repeated again. See Step III below for how to interpret the ABS Indicator Lamp flashes. |
III | Count the flashes from the ABS Indicator Lamp each time the Diagnostic Push Button is pressed to determine the Blink Code(s). Write down only the first 4 or 5 Blink Codes for faults recorded on the ECU (there may be several stored in the memory). | Following each activation of the button, a period of approx. 3 seconds elapses before the Blink Code is displayed. The Blink Code for a fault is in two parts 'tens' and 'units'. The flashes for the 'tens' are of longer duration than those for the 'units' (see diagram above). | The Blink Codes '1' and '10' both give only one flash of the ABS Indicator Lamp, and the codes can be differentiated only by the duration of the flash. Note - there is no configuration code displayed as the KB-92 System has a fixed configuration. |
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: Whilst pressing the Diagnostic Push Button, switch ignition ON, and hold button for a further 3 seconds. Release button and the memory is cleared. | 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 II and 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 |
