PERFORMING DIAGNOSTIC
4.1 Compability
The shock absorber connections on the patch cable (RC and RR)
are compatible with the stepper motors 21704-XX.
The fork connections on the patch cable (FC and FR) are compatible
with stepper motors 21717-XX.
The preload connection on the patch cable (PL) is compatible with
preload adjuster motor unit 21762-01.
Other preload adjuster motor units can be diagnosed with this tool
but since the hydraulic ratio may differ, the adjustment range will not
be correctly displayed.
4.2 Check EC Motors
4.1.1 Perform Diagnostics
1. Adjust the spring preload to the lowest level before disconnecting
the motor from the vehicles wire harness.
2. Connect the patch cable to the product. See chapter “Connecting
the diagnostic tool”.
3. Start the Diagnostic Program on your computer. See chapter
“Diagnose a system”.
4. Turn on the power on the EC Diagnostic Tool.
4.1.2 Evaluation
Expected results if no errors on the motors:
• No error messages in the message box. See chapter 5.
• Stepper motors react to adjustments. See chapter 5.
• Preload adjuster reacts when applying more and less preload.
See chapter 5.
If you get an error code or no/incorrect reaction on adjustments
replace the faulty component and redo the diagnosis.
4.3 After Diagnostics
Adjust the spring preload to the lowest level and connect then the
motors to the vehicle´s wire harness.
The stepper motors are calibrated automaticly by the ECU. The
preload adjuster has to be manually checked and calibrated if
needed. If the preload is incorrect, adjust the preload to highest and
then lowest level using the vehicle´s controls.
