Where this comes from

Only Emtron's own documents. Pin names and notes are written exactly as Emtron writes them.

How we checked it

  • We start from Emtron's pinout page for this ECU, on its Resource Centre.
  • Every pin is read again in Emtron's wiring harness specification for the ECU family, which lists each pin with its name, description and wire colour. A script compares them pin by pin.
  • A pin is only shown when both name the same function. A pin the ECU's pinout marks NC is shown as not connected; where the family's harness specification lists something there, the page says so. A wire colour is shown only when a second Emtron harness specification gives the same colour for that pin name.
  • Labels are Emtron's own words from the pinout page; notes are its words from the harness specification.

Where Emtron's documents disagree

B29: Emtron's SL Series wiring harness specification lists CAN 2 HI (Auxiliary CAN) on B29, and Emtron's 2018 ECU comparison sheet gives the SL6 two CAN channels. The SL6 pinout lists the pin as NC (not connected). Shown: not connected, as in the SL6's own pinout.

B30: Emtron's SL Series wiring harness specification lists CAN 2 LO (Auxiliary CAN) on B30, and Emtron's 2018 ECU comparison sheet gives the SL6 two CAN channels. The SL6 pinout lists the pin as NC (not connected). Shown: not connected, as in the SL6's own pinout.
