Timeout on CAN in communication with ELC.
Check the ELC for related DTCs. • Check other ECUs for DTCs indicating time-out from the unit ELC. • Check unit ELC: - Fuse - Wiring to Supply Voltage (30), System Ground (31), and Ignition (15) - Check CAN connections • Check CMS::ECU (E113) connection to Subbus1 CAN (wiring and connectors). The battery should be disconnected. - Disconnect harness connector on ECU side, and measure the resistance between pins A11 and A14. It should be approximately 60 ohm (two 120 ohm termination resistors in CAN-bus network).
What you'll see
