The brake transaxle shift interlock (BTSI) system requires that you press the brake pedal in order to move the gear selector from the PARK position. The powertrain control module (PCM) monitors the BTSI switch and the park neutral position (PNP) switch. The PCM sends the position of the 2 switches to the IPC through a class 2 serial data line. If the gear selector is in PARK and the brake pedal is not pressed, the IPC displays this message.

Once this message displays, the message continues to display until one of the following actions is completed:

The message has a minimum display time of 3 seconds regardless of the brake position.

You may cancel the APPLY BRAKE TO SHIFT message by pressing the OFF and cooler (blue) buttons simultaneously for 5 seconds. Once you cancel the message, you can bring it back with the same procedure.

The IPC monitors the alternator L terminal input on IPC connector C1 terminal A9. The IPC uses the input in order to determine when to set IPC DTC B1911 current. The IPC uses this input when the L terminal is low and the engine runs over 600 RPM for more than 2 seconds. If the alternator is not charging, the L terminal input is low (ground). If the alternator is charging, the L terminal input is at the ignition voltage. When DTC B1911 is set current, the IPC displays the message and illuminates the battery indicator.

The IPC monitors battery voltage on IPC connector C1 terminals A1 and B1. If battery voltage is below 10 volts with the engine running, DTC B1981 is set current and the IPC displays the BATTERY VOLTAGE LOW message.
