Ignition "OFF".
Disconnect "PCM" connector.
Measure resistance between CAN high terminal and CAN low terminal of PCM harness connector.
Specification : Approx. 120 Ω ± 10Ω
Is measured resistance within specifications?
| ▶ Substitute with a known-good "PCM/TCM" and check for proper operation. If the problem is corrected, replace "PCM/TCM" and Go to "verification of vehicle repair" procedure |
| ▶ Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage of ECM.and then Repair or replace Resistance for CAN communication as necessary and go to "Verification Vehicle Repair" procedure |
