Make:
Buick
Code:
B101E 46
Definition:
Front Axle System Short to Ground
Description:
Ignition ON.  System voltage 10.5-18 V.
Cause:
The TCCM monitors the front axle switch signal circuit and the front axle actuator control circuit for unexpected voltages.  The DTC sets if the TCCM detects a high voltage when a low voltage is expected,  or a low voltage when a high voltage is expected.
Failure Type:
Calibration / Parameter Memory Failure
This sub type is used by the control module to indicate a calibration / parameter memory failure for embedded systems using FLASH memory. This is equivalent to EEPROM in RAM/ROM/EEPROM embedded systems.
