Hi,
Event Code 101
Access 1 does not communicate with Access 2/3.
Step 1: Turn off the vehicle.
Step 2: Verify that B-NEG is present at Access 1 CA302-01, and the Access 2/3 B-NEG terminal.
* If: B-NEG is present at all the modules - Then continue to step 3
Step 3: Perform a CAN circuit test using the following
table.
1. Disconnect CA607.
2. Check the resistance between CA607-1 and CA607-2.
3. The resistance should be approximately 120 ohms.
4. Replace the terminating resistor if the resistance less than 115 ohms or greater than 125 ohms.
5. Check the resistance of the CAN circuit if the terminating resistor has a resistance between 115 ohms and 125 ohms.
6. Replace the appropriate module if the terminating resistor and CAN circuit test find no faults.
