Details of the c1415 OBD Code
C1415 code indicates a malfunction in the right front wheel speed sensor circuit.
OBD code C1415 means Right Front Wheel Speed Sensor Circuit High.
This code is triggered by the ABS module when it detects a high voltage signal from the right front wheel speed sensor circuit.
The ABS module monitors the wheel speed sensors to ensure proper ABS operation and traction control.
When the voltage from the right front wheel speed sensor circuit is higher than expected, it sets this diagnostic trouble code (DTC) C1415.
Mechanic’s Tech Notes
Code C1415 indicates a malfunction in the right front wheel speed sensor circuit.
OBDII code C1415 relates to a malfunction in the transmission control module (TCM) power supply.
To diagnose this issue, use a voltmeter to check TCM power and ground connections for proper voltage levels.
Utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect wiring harnesses and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection will help pinpoint the root cause of the C1415 fault code.
