CAN communication Line Inspection

1. Ignition "OFF".
2. Connect SRSCM and OCS (Occupant Classification System) ECU connector.
3. IG KEY ON.
4. Measure signal waveform between CAN HIGH terminal and CAN LOW terminal of OCS (Occupant Classification System) ECU connector.

   Specification:  Refer to SIGNAL WAVEFORM AND DATA 

5. Is the measured signal waveform normal?

   YES 

   • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
   • Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Substitute a known-good OCS (Occupant Classification System) ECU and check for proper operation.
