- Is the result within specifications?
YES
- Go to next procedure.
NO
- In case of the resistance "approx. 1Ω" in both measurement: Repair mutual short in C-CAN signal circuit of the ESP (ESC) and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- In case of the resistance "approx. 120Ω" in both measurement: Go to "COMPONENT INSPECTION " procedure.
- In case of the resistance "∞ Ω" in both measurement: There is open circuit between ESP (ESC) connector and other ECUs, go to "CAN BUS LINE OPEN/SHORT INSPECTION " procedure.
