Details of the b253a OBD Code
Fault code B253A relates to a problem with the ignition switch position circuit.
OBD code B253A means Ignition Accessory Relay Coil 1 Control Circuit High.
This code is triggered when the powertrain control module (PCM) detects a high voltage condition in the control circuit for the ignition accessory relay coil 1. The ignition accessory relay is responsible for providing power to various accessories in the vehicle, such as the radio, power windows, and interior lights.
When the PCM detects a high voltage in this circuit, it sets code B253A to indicate a potential issue with the relay or its control circuit.
Mechanic’s Tech Notes
Code B253A relates to a fault in the keyless entry system’s antenna circuit.
OBDII code B253A typically indicates an issue with the Transmission Control Module (TCM) power or ground circuits.
To diagnose this, use a multimeter to check the TCM power and ground connections for proper voltage levels.
Additionally, utilize a scan tool to confirm if the TCM is communicating over the Controller Area Network (CAN) network.
If the TCM is unresponsive, reprogramming or reflashing it may be necessary.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection can help pinpoint and resolve the root cause of the B253A fault code.
