Is voltage within the specification?
 | ▶ Go to next step as below |
 | ▶ Repair CAN communication line for Open. And then go to "Verification of Vehicle Repair" procedure |
Disconnect the connectors related to the CAN communication
Ignition "ON" & Engine "OFF"
Measure resistance between High signal terminal of PCM and TCM.
Measure resistance between Low signal terminal of PCM and TCM.
Specification : Approx. 0Ω
Is voltage within the specification?

Ignition "OFF".
Measure resistance between High signal terminal and Low signal terminal of PCM connector(PCM side).
Specification : Approx. 110~130Ω
Is resistance within the specification?
| ▶ Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure. |
| ▶ Check PCM for contamination, deterioration, or damage. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure. |
