After pressing the key > , a selection menu is displayed: After the last displayed error, the following instruction appears:
Menu
1 = Fault memory
2 - Drive links
3 = input signals
Proceed with key >
c Menu
1 = System adaptation
Repair fault according to repair instructions
Continue: >
In the example - press key t. There then foliaws the display of the number of errors which are stored (if any).
Number of faults
Proceed with key
Additional info to every display with key 1 continue:
Proceed with key Error output:

If key 1 is pressed instead of the key, the corresponding error code display appears (the last two digits of the flashing code).
Proceed with key >
Further errors are displayed (if they exist):
2: Idle contact
Short to ground present
If keyl is pressed instead of key the corresponding error-code display appears (the last two digits of the flashing code).
Return to display "No. of errors" with key 3. proceed with key 1:
Fault memory 1 = Erase 3 = Do not erase
(f key 3 is pressed: = Return to menu "error memory", The error memory is not erased I
Proceed with key 1:
Fault memory has been cleared
Return:
The test scope "Read-out error memory" is terminated at this point.
3.2 Actuator diagnosis
If a n actuator is selected, this is triggered by the ECU so that it ca n be checked for correct functioning.
The various actuators components are gone through one after the other and are selected with the key.
Operate the Systemtester 9288 as described under 3.1 until the following menu display appears:
Menu
1 = Fault memory
2 = Drive links
3 - Input signals
After pressing key 2, the display for the first actuator appears:
Injector to activate 1 - Start Continue :
If key is pressed, the next actuator is selected. Pressing key 1 results in the following instruction:
Key 1 selects the next actuator (e.g. idle actuator). Following instruction:

Proceed with key
Idle stabilizer to activate 1 = Start Continue :
After pressing key 1, the following display appears:
Can idle stabilizer be heard / felt ? 1 = yes 3 = no
By pressing key 1, the next actuator is selected.The actuatorsare selected one after the other and triggered until the following display appears:
Drive link test completed
Return: N
By pressing the key N, the operator is returned to the menu.
3.3 Circuit inputs
In addition to the actuators, the Syslemtester 9288 can also check circuit inputs. To this end, operate the Systemtester 9288 in accordance with 3.1 until this menu display appears:
Menu
1 = Fault memory
3 = Input signals
Press key 3
Idle contact 1 = Start
Continue:
By pressing key the next circuit input is selected. The next display appears when key 1 is pressed.
