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

IG key "ON", Engine "OFF".
Disconnect "BCM" connector and "SMART JUNCTION BLOCK_IPS CONTROL MODULE"(SJB) connector.
Measure the resistance between "B_CAN High" terminal of "BCM" harness connector and "B_CAN High" terminal of SJB harness connector.
Measure the resistance between "B_CAN Low" terminal of "BCM" harness connector and "B_CAN Low" terminal of SJB harness connector.
Specification : Below aprox. 1Ω
Is the measured value within specifications?
| ▶ Fault is intermittent caused by poor contact in SJB connector. → Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. → Repair or replace as necessary, go to "Verification of Vehicle Repair" procedure. |
| ▶ Repair open/poor connection in the abnormal terminal/harness. → Repair as necessary, go to "Verification of Vehicle Repair" procedure. |
