A/V & navigation head unit connector | 20 (M-CAN low) | Chassis ground | - | ∞ (infinity)Ω |
| A/V & navigation head unit connector | 7 (M-CAN high) | Chassis ground | - | ∞ (infinity)Ω | |
| A/V & navigation head unit connector | 20 (M-CAN low) | ICU connector | 8 (M-CAN low) | Approx. below 1Ω | |
| A/V & navigation head unit connector | 7 (M-CAN high) | ICU connector | 7 (M-CAN high) | Approx. below 1Ω | |
Good
- Remove each unit/module connector that constitutes the M-CAN communication network, and check if the DTC is cleared
- If a steady value is measured when the connector is removed, check the grounding short of the respective component and communication line.
- Repair or replace as necessary and then go to "Verification of Repair " procedure.
No Good
- If the voltage of the measured waveform is at the approx. 12V, check for short circuit to battery.
- If the voltage of the measured waveform is at the approx. 0V, check for short circuit to ground.
- Check the circuit open or connector disconnection.
- Check for a short circuit between the wiring and the chassis ground.
- Perform repair or replacement as necessary and perform the "Verification of Repair " procedure.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
