Timeout on CAN in communication with EQU
Check the EQU for related DTCs. • Check other ECUs for DTCs indicating time-out from the unit EQU. • Check unit EQU: - Wiring to Supply Voltage (30), System Ground (31), and WakeUp - Check CAN connections • Check CMS::ECU (E113) connection to Subbus2 CAN (wiring and connectors). The battery should be disconnected. - Disconnect harness connector on ECU side, and measure the resistance between pins A35 and A38. It should be approximately 60 ohm (two 120 ohm termination resistors in CAN-bus network).
What you'll see
• Instrument cluster will display warning.
