Details of the c2116 OBD Code
Code C2116 relates to a malfunction in the ABS motor relay circuit.
OBD code C2116 means ABS Pump Motor Supply Low Voltage.
This code is triggered by the ABS control module when it detects that the voltage supplied to the ABS pump motor is below the specified threshold.
The ABS pump motor is responsible for building hydraulic pressure in the ABS system to assist with braking.
When the voltage supplied to the motor is insufficient, it can lead to improper ABS system operation and potentially compromise vehicle safety.
Mechanic’s Tech Notes
Code C2116 indicates a malfunction in the ABS pump motor circuit.
OBDII code C2116 typically indicates a fault with the ABS pump motor supply voltage circuit.
To diagnose, use a voltmeter to check the power and ground connections to the ABS module.
Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Verify communication between the ABS module and other control modules using a scan tool over the CAN network.
If no issues are found with the wiring or connections, the problem may lie within the ABS module itself, requiring further testing or potential reprogramming.
