DTC B1492: Generator "F" Terminal Low: Description

DTC B1492 will set when a fault exists that is causing generator PWM to read LOW continuously. This DTC will be set when PCM is sending "engine is running" and "generator PWM is less than 1.96 percent" class 2 data messages, field terminal present calibration is enabled in PCM, and engine is running at about 3000 RPM for 30 seconds.

When DTC B1492 is set, VOLTS indicator will illuminate. DTC B1492 can be cleared using scan tool, or history DTC will disappear after 100 ignition cycles if fault conditions do not reoccur.
