1.
Check CAN communication waveform generation
1)
Ignition "OFF"
2)
Connect 2 channel scope to DLC terminal 3(CAN HIGH) and 11(CAN LOW).

3)
Ignition "ON" after connecting only PCM to CAN BUS.
4)
Ignition "ON" after connecting only ABS or ESP module to CAN BUS.
Specification : At Ignition "ON", the waveform same as "Signal Waveform &
Data" of above signal waveform.
※ Different from "Signal Waveform & Data", if 1) both CAN HIGH and LOW signal are fixed at 2.5 V or
2) HIGH and LOW signal are fixed at 3.5 V and 1.5 V, respectively, it is due to communication error between modules.

Does correct waveform generate from each module?
YES
▶ Go to "Verification of Vehicle Repair".
NO
▶ Replace the module which generates poor communication waveform, and go to "Verification of Vehicle Re-
pair".
VERIFICATION OF VEHICLE REPAIR
EDE62C44
After a repair, it is essential to verify that the fault has been corrected.
1.
Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
2.
Using a Scantool, Clear the DTCs
3.
Operate the vehicle within conditions noted in the freeze frame data or enable conditions
4.
Monitor that all rediness test have been verified as " Complete "
5.
Are any DTCs present ?
YES
▶ Go to the applicable troubleshoooting procedure.
NO
▶ System is performing to specification at this time.
