ZN065 PWM voltage converter: feeding the PWM lines at 5V during bench ECU reading

Strumenti Interface Classic Hardware / Connections Advanced ⏱ 10 min 5 steps

The ZN065 is the PWM voltage converter: it is only used in the cases where reading an ECU on the bench requires the PWM lines to be fed at 5V instead of the usual 3.3V.

⚠ WarningThe ZN065 is compatible ONLY with DS Box version 2.3. Do not use it with other Distribution Box versions and do not fit it when the procedure does not specifically call for 5V on the PWM lines.

Procedure

  1. Check the version of your Distribution Box: the ZN065 only works with DS Box v. 2.3.
  2. Check that the bench ECU reading procedure calls for the PWM lines at 5V; if it works with the normal 3.3V, do not fit the converter.
  3. Fit the ZN065 - PWM voltage converter into the connection chain between DS Box and ECU.
  4. Power up the bench and start the read from the Abrites software.
  5. When the job is done, remove the converter so you are back to the standard 3.3V setup for the next jobs.
