Not Automotive Ethernet Legacy Networks (ALDL Networks) CAN-C is being measured. What should Meter A display based on the fault shown? 0.0V What type of fault could be indicated when all modules on a SINGLE bus appear as unresponsive on the wiTECH topology? Select all that apply. Faulty Gateway Module What are the key differences between CAN-FD and CAN-C? Select all that apply. Similar bias voltage Same termination resistance CAN-FD modules can send larger messages at a faster transmission speed CAN-FD Modules can send up to 64 bytes between 500 kbps or 2 mbps (FD- Flexible Data) With the bus active and no faults present, what voltages should be measured on CAN-B (-)? 4.65V-4.98V CUSW found on? 2013 Dodge Dart 2014 Jeep Cherokee 2015 Chrysler 200 Now only on the KL Cherokee TIPM Found on? 2020 RT Grand Caravan and Town and Country 2018 JK Jeep Wrangler 2017 MK Jeep Compas TIPM is combined BCM and PDC CAN-C and IHS(older models use CAN-B instead of CAN-IHS similar to FIAT7209 LIN (Local Interconnect Network) Bus Lower priority modules Smart Sensors Actuators Single Wire that provides less bandwidth than CAN 8 bytes at up to 19.2 kbps(25 times weaker than CAN-C DMM averages voltage readings to 7-10 VDC while communicating Diagnosis A single module unresponsive can mean no power, poor ground, or open on the CAN Bus stub All modules on one bus unresponsive caused by a CAN Bus short to ground, power, or together;disabling the whole bus. All modules on every bus appearing red could mean a problem with the CAN Circuits at the DLC. This could mean an SGW Issue like a blown fuse or lost ground. Use a DLC BOB to check for DLC Voltage and perform all necessary tests before replacing an SGW A variety of modules unresponsive across the bus could mean a fault with a common power or ground circuit A group of unresponsive modules that share a communication bus might mean an open circuit What is the total termination resistance used on a CAN-B bus?
