Hitachi ZX200‑5G CAN Fault Codes 11006, 11007, 16604

Hitachi ZX200-5G / ZX210-5G CAN Communication Fault Codes (11006, 11007, 11009, 16604, 13002, 13003, 13005) – Troubleshooting Guide

Hitachi ZX-5G series excavators use a CAN-bus communication system to connect the Engine Controller, Monitor Controller, ECF, and other electronic modules. When communication is lost, the machine displays fault codes such as 11006, 11007, 11009, 16604, 13002, 13003, 13005.

All these codes point to a CAN0 communication failure — usually caused by wiring issues, connector problems, or a controller not responding. This guide explains the meaning of each code, possible causes, and step-by-step troubleshooting.

1. Fault code meanings (simplified)

CAN0 network diagram showing Engine Controller, Monitor Controller, ECF, and Information Controller connected via CAN-H and CAN-L lines in Hitachi ZX200-5G / ZX210-5G excavators

11006-2 — Engine Controller Communication Error
The Engine Controller is not communicating on the CAN0 line.

Possible causes:
Open circuit in CAN wiring
Short circuit in CAN wiring
Loose or corroded connector

11007-2 — Monitor Information Controller Communication Error 1
The Information Controller lost communication on CAN0.

Possible causes:
Open circuit in CAN wiring
Short circuit in CAN wiring
Connector problem (loose, dirty, or damaged)

11009-2 — Monitor Controller Communication Error 1
The main monitor is not receiving CAN0 data.

Possible causes:
CAN wiring open
CAN wiring shorted

16604-2 — CAN Communication Error
General CAN-bus failure on the machine.

Possible causes:
CAN-H or CAN-L open
CAN-H or CAN-L shorted
One controller not responding on the CAN line

13002-2 — ECF Communication Error
The Engine Control Function (ECF) module is not communicating.

Possible causes:
Open circuit in CAN wiring to ECF
Short circuit in CAN wiring

13003-2 — MC Communication Error
The Monitor Controller is not responding on the CAN network.

Possible causes:
Open circuit in CAN harness
Short circuit in CAN harness

13005-2 — Monitor Information Controller Communication Error 1
The Information Controller lost CAN communication.

Possible causes:
Open circuit in CAN harness
Short circuit in CAN harness

2. Common root cause – CAN0 communication line problem

Even though the fault code numbers are different, they all point to the same system: the CAN0 communication line.

Typical problem areas:
CAN-H / CAN-L wiring damage
Loose or corroded connectors
Incorrect or failed termination resistors
Controller power supply or ground issues

3. Step-by-step CAN communication troubleshooting

Step 1 – Visual inspection of connectors

Inspect all CAN-related connectors between controllers.
Look for corrosion, bent pins, moisture, or loose locking tabs.
Clean, dry, and reconnect all suspect connectors.

Step 2 – Continuity check of CAN wiring

Use a multimeter to check continuity of CAN-H from one controller to the next.
Repeat the same for CAN-L.
If continuity is open → there is a break in the harness.

Step 3 – Check for short circuits

Measure resistance between CAN-H and ground.
Measure resistance between CAN-L and ground.
Measure resistance between CAN-H and CAN-L.
Any reading close to 0 ohms indicates a short circuit.

Step 4 – Check termination resistance

Disconnect power to the machine.
Measure resistance between CAN-H and CAN-L on the harness.
Expected value is normally around 60 ohms (two 120 Ω terminators in parallel).
120 Ω → one terminator missing.
0–10 Ω → short circuit on CAN line.
Infinite (open) → broken wiring or both terminators missing.

Step 5 – Wiggle test on harness

While measuring resistance, gently move and bend the harness.
If readings jump or drop, there may be an internal break in the wires.

Step 6 – Check controller power and ground

Verify proper battery voltage at each controller power supply pin.
Check ground continuity and voltage drop on ground circuits.
A controller with no power or poor ground can cause CAN communication errors.

Step 7 – Controller replacement (last option)

Only consider replacing a controller after wiring, connectors, and power supply are fully confirmed OK.
Most CAN faults are harness or connector related, not controller failure.

4. Technician tips for ZX200-5G / ZX210-5G CAN faults

Most CAN errors are caused by connectors, not ECUs.
Moisture and corrosion inside connectors are common causes, especially in hot and humid regions.
Always check and clean grounds when you see multiple communication codes together.
Do not twist, stretch, or crush the CAN-H and CAN-L twisted pair more than necessary.

5. When multiple CAN fault codes appear together

If several communication codes appear at the same time, for example: 11006, 11007, 11009, 16604, 13002, 13003, 13005, this usually indicates that the CAN0 line is down completely.

Possible reasons:
Major open circuit in the main CAN harness
Short circuit pulling CAN line low or high
One failed controller blocking CAN communication

Recommended check order:

Start at the monitor and engine controller connectors.
Check any CAN junction blocks or intermediate connectors.
Then move along the harness to other controllers.

6. Conclusion

These Hitachi ZX200-5G / ZX210-5G CAN communication fault codes all point to problems on the CAN0 communication network, not just one single controller.

By following a structured troubleshooting process — visual connector check, continuity testing, short circuit detection, termination resistance measurement, harness wiggle test, and power/ground verification — you can quickly determine whether the root cause is wiring, connectors, termination, or a failed module.

Understanding these codes and the CAN0 system will save significant diagnostic time and help prevent unnecessary controller replacement on Hitachi ZX-5G series excavators.

FAQ

Q1: What causes Hitachi fault code 11006? A CAN‑bus communication failure between the Engine Controller and Monitor Controller, usually due to wiring issues or poor connector contact.

Q2: How do I fix Hitachi error 16604? Check CAN‑H and CAN‑L continuity, inspect connectors, measure termination resistance, and verify controller power supply.

Q3: Are Hitachi CAN errors usually wiring or ECU problems? Most CAN errors are caused by wiring, corrosion, or poor grounding — not ECU failure.

Q4: What is the normal CAN‑bus resistance on Hitachi ZX‑5G? Around 60 ohms between CAN‑H and CAN‑L with power off.
