Alarm 2010 — Meaning Depends on Controller: Conf digital input 1 alarm / Coolant Temperature
The ATLAS-COPCO-2010 (Atlas Copco Xc-series controller (Xc1004 / Xc2003 / Xc4004)) diesel fault code means: Alarm 2010 — Meaning Depends on Controller: Conf digital input 1 alarm / Coolant Temperature. This is a serious severity code.

A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Common Symptoms
- Alarm 2010 shown on the Xc-series controller display
- Machine may shut down or refuse to load, depending on the alarm class
Probable Causes (Ranked by Likelihood)
- Depends on the controller fitted — see the per-controller meanings in the diagnostic steps High
- Sensor, switch or wiring fault in the monitored circuit producing a false alarm Moderate
Step-by-Step Diagnostic Procedure
Identify which Xc-series controller your machine has FIRST (Xc1004, Xc2003 or Xc4004 — it is named on the controller face or in the machine documentation). The same alarm number can mean different things on different controllers, so the controller identity is part of the diagnosis.
Note: on controllers where this number is a 'configurable digital input' alarm, the meaning is machine-specific — the input is wired to whatever protective device the packager chose. Check the machine's own documentation for what this input monitors on your unit.
On Xc2003: alarm 2010 = Conf digital input 1 alarm
On Xc1004: alarm 2010 = Coolant Temperature
On Xc4004: alarm 2010 = Low pumper oil pressure alarm
Stop the machine and check the oil level before anything else. Do not keep restarting against a possible real loss of oil pressure — if the level is correct, verify the switch/sensor and its wiring before condemning anything expensive.
Let the machine cool, then check coolant level and the cooler for blockage. Repeated trips with good coolant level point at the sensor or a genuine cooling-system fault, not something to reset past.
High-temperature alarms on a compressor are usually oil level, cooler cleanliness, or ambient conditions before they are sensors — check those in that order.

Frequently Asked Questions
What does Atlas Copco alarm 2010 mean?
It depends on the controller. On Xc2003: alarm 2010 = Conf digital input 1 alarm On Xc1004: alarm 2010 = Coolant Temperature On Xc4004: alarm 2010 = Low pumper oil pressure alarm Identify your controller before acting on any single interpretation.
How is the severity on this page decided?
Atlas Copco's published alarm table names each alarm but does not grade severity, so the rating here is inferred from the alarm's function (shutdown-class alarms rated higher than warnings and service reminders). Treat any alarm that stops the machine as serious regardless of the label.
