NOTICE: An B1557 DTC will be set if the flowing procedure is not followed. An B1557 is not recoverable and the IPC will have to be rep laced. If, while performing the flowing procedure, the "OFF" button is pressed and the IPC displays "IPC CLEAR CODES" Exit on board diagnostics and start over. This will reset the options back to their original settings and prevent B1557 from setting.

To permanently store the changes, press and hold "FRONT DEFROST" and "AUTO/ECON" (Digital IPC) or "FRONT DEFROST" and "A\C" (analog IPC) until the value on the Trip Odometer flashes once (approximately five seconds).
