Signal Circuit Inspection

■ Check CAN high circuit 

1. IG "ON" & ENG "OFF".
2. Connect GDS and select Scope meter function.
3. Measure signal waveform of PDM CAN High line.

   Specification:  Refer to SIGNAL WAVEFORM AND DATA 

4. Is the measured signal waveform of CAN high circuit normal?

   YES 

   • Go to next procedure

   NO 

   • Check short to battery/ground in CAN high circuit, and repair or replace as necessary. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check CAN Low circuit 

1. IG "ON" & ENG "OFF"
2. Connect GDS and select Scope meter function.
3. Measure signal waveform of PDM CAN Low line.

   Specification:  Refer to SIGNAL WAVEFORM AND DATA 

4. Is the measured signal waveform of CAN low circuit normal?

   YES 

   • Go to next procedure.

   NO 

   • Check short to battery/ground in CAN low circuit and, repair or replace as necessary. And then, go to 'VERIFICATION OF VEHICLE REPAIR " procedure.
