Has a problem been found?
 | ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "CAN communication circuit inspection" procedure. |
Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

IG KEY OFF.
Connect PCM, ESP, EPS, BSD connector.
Measure registance between terminal 3 and 11 of diagnostic connector.
Specification : About 60 Ω
Is the measured resistance within specification ?
| ▶ Check Each Module 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. |
| ▶ If the measured value is lower than 10Ω, repair or replace CAN High and CAN Low are short each other. And then, go to "Verification of Vehicle Repair" procedure. ▶ If the measured value is ∞ Ω, repair or replace the open in CAN High /CAN Low circuit. And then, go to 'Verification of Vehicle Repair" procedure. |
IG KEY OFF.
Disconnect PCM, EPS(MDPS), and BSD connector.
IG KEY OFF
Measure voltage between CAN high terminal(
Is the measured value within specification ?
| ▶ Check PCM, EPS, BSD ECU and ESP 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. |
| ▶ Check short to battery in communication line. And then, go to 'Verification of Vehicle Repair" procedure. ▶ Check short to ground in communication line. And then, go to 'Verification of Vehicle Repair" procedure. |
