Subject:EI08045 - Key Cannot Be Removed from Ignition with Gear Selector in Park, Shifter Cannot Be Moved from Park Position (Repair/Reroute Brake Transmission Shift Interlock (BTSI) Solenoid Harness)

Models:2007-2009 Chevrolet Impala

 



Condition

Some customers may comment on either of the following conditions:

The key cannot be removed from the ignition.

The transmission gear selector (shifter) cannot be moved out of the PARK position.

Cause

This condition may be caused by an incorrectly routed brake transmission shift interlock (BTSI) solenoid harness which can make it difficult to install. In some instances, the wiring looms are tangled, causing stress on the wires in the connector at the BTSI. If the BTSI harness is routed incorrectly, it may also result in a wire pinching issue.

Correction

Important: DO NOT use force to move the gear selector (shifter). Using force may cause damage to the BTSI.

Inspection/Routing and Repair of the BTSI Wiring Harness/Connector

  1. Check for wire damage at the BTSI connector terminal ends. Refer to SI for repair procedures.
  2. For very intermittent issues, check the BTSI wire harness individual circuits for broken or crimped wires. Refer to SI for repair procedures.
  3. BTSI Wiring Harness Incorrectly Routed
