CAN Communication Line Inspection
- Ignition switch "OFF"
- Disconnect battery (-) cable.
- Refer to "ABS CONTROL UNIT and DCT CONTROL MODULE (TCM) (1.6L) or ENGINE CONTROL MODULE (ECM) (2.0L/2.4L) " and disconnect HECU and TCM/PCM connector.
- Measure the resistance between Pin No. 44 (C-CAN High) terminal of HECU harness connector and Pin No. 44 (C-CAN High) terminal of TCM harness connector. (1.6 T-GDI)
- Measure the resistance between Pin No. 45 (C-CAN Low) terminal of HECU harness connector and Pin No. 45 (C-CAN Low) terminal of TCM harness connector. (1.6 T-GDI)
- Measure the resistance between Pin No. 44 (C-CAN High) terminal of HECU harness connector and Pin No. 77 (C-CAN High) terminal of PCM harness connector. (2.4 GDI, 2.0 T-GDI)
- Measure the resistance between Pin No. 45 (C-CAN Low) terminal of HECU harness connector and Pin No. 60 (C-CAN Low) terminal of PCM harness connector. (2.4 GDI, 2.0 T-GDI)
Specification: Approx. below 1 Ω
- Is the measured value within specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Repair open in C-CAN circuit and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
