"Apply Brake to Shift" Message

Wiring Diagram:

CIRCUIT DESCRIPTION

The Brake Transaxle Shift interlock (BTSI) system requires that the regular service brake be applied to shift the vehicle out of Park. The PCM monitors the brake switch and the transmission position and transfers this information to the IPC via serial data. If the transmission is in Park and the brake is not on, this message will be displayed.

Once this message is displayed, it will continue to displayed until the brake is applied or the "STORE / RECALL" button is pressed. This message has a minimum display time of 5 seconds regardless of brake position.

TEST CONDITION(S)

1. Transmission in Park (from PCM data)

2. Message enabled in EEPROM option word #2 (refer to Diagnostic Parameters - BS09)

FAILURE CONDITION(S)

1. Brake Switch indicates brake not applied (from PCM data) for 5 seconds.

NOTE:

The "APPLY BRAKE TO SHIFT" message can be cancelled by pressing the "OFF" and "COOLER" buttons simultaneously for 5 seconds. Once the message is cancelled, it can be brought back with the same procedure.
