Resistance Measurement With Matching Resistor
- Ignition "OFF" and disconnect the battery and wait about four minutes.
- Make sure all modules are properly connected.
- Measure resistance between Pin No. 5 (C-CAN High) and Pin No. 4 (C-CAN Low) terminal of IGPM harness connector.
Specification: Approx. 60 Ω
- Is the measured value within specification?
YES
- Go to "CAN Signal Inspection" procedure.
NO
- If the value is out of specification then, go to "CAN RESISTOR INSPECTION " procedure.
* If the measured value is approx. 0Ω, then check for short CAN communication line.
* If the measured value is approx. ∞Ω, then check for open CAN communication line.
