A C1100 trouble code means that your 2012 Mitsubishi Eclipse spyder's Engine Control Unit (ECU) has registered an unspecified circuit failure in the Antilock Braking System's pump switch circuit.
The antilock braking system offers your 2012 Mitsubishi Eclipse spyder added traction. If the ABS pump isn't working properly, the ECU will run a diagnostic test to verify whether the parameters for a C1100 have been met. If a C1100 code has occurred and the pump switch circuit has failed, this will restrict use of the ABS system.
A faulty ABS pump, sensor and/or control unit could explain the failed ABS circuit. Multiple ABS circuit failure are sometimes solved at once by replacing a single sensor. It may also be caused by a problem with the wiring and electrical connectors. Improper wiring or corroded, damaged and otherwise faulty circuitry may be to blame for this circuit failure. In some rare cases, the ECU itself may be faulty, mistakenly reporting the trouble code as a result. Due to the rareness of this cause, it should only be considered once all other plausible causes have been exhausted.
The ABS system will be disabled or seriously hindered in the event of a C1100 code. In addition to the practical concerns, the C1100 code will be accompanied by an illuminated check engine light on your 2012 Mitsubishi Eclipse spyder's dashboard, as well as a stored trouble code in the ECU that can be read using an OBD-II scanner. These symptoms are present in a purely diagnostic context, and may be disregarded once the specific issue has been identified.
The C1100 code is first diagnosed by reading the code using an OBD-II scanner on your 2012 Mitsubishi Eclipse spyder's ECU. Components (including the control unit, sensor and the pump itself) should be looked over to see if one of them is faulty. Any wiring and electrical connector related to the pump switch circuit should be looked over thoroughly for signs of damage, corrosion and disconnection. An additional diagnostic tool such as the Autohex scanner may help in pinpointing the source of the circuit failure.
Chassis (or C-class) trouble codes may describe different issues depending on the make and model of 2012 Mitsubishi Eclipse spyder in question. For instance, in the specific case of Mercedes 2012 Mitsubishi Eclipse spyders, the C1100 code refers to a circuit fault in the left-front axle. Your OBD-II scanner may specify the code description for you. If you're not sure if you're interpreting the code correctly, refer to your 2012 Mitsubishi Eclipse spyder's user manual, or contact the manufacturer.
Your 2012 Mitsubishi Eclipse spyder will handle differently than usual without its proper ABS traction. Although your 2012 Mitsubishi Eclipse spyder may still technically be drivable without the Antilock Braking System, it significantly increases the risk of accidents. A C1101 trouble code is considerably more serious if your 2012 Mitsubishi Eclipse spyder is typically driven on less-than-optimal driving conditions and routes.
Any electrical wiring and connectors that have been identified as broken, damaged, or faulty should be replaced, repaired, or rewired accordingly. In the rare event that the ECU has been identified as faulty, it will need to be reprogrammed or replaced altogether. Once you've made any necessary repairs to fix the ABS pump switch circuit, restart your 2012 Mitsubishi Eclipse spyder. If the C1100 hasn't been properly solved yet, this will give the trouble code a chance to recur. In the event that the issue hasn't been solved, return to the diagnostic stage and see if there is anything you may have missed.
Virtually all modern cars come equipped with ABS braking.
