Overview
The transaxle selector lever linkage consists of
- a selector lever cable that connects the transaxle manual control lever to the selector lever assembly.
- a BSIA that is integral to the selector lever assembly.
- a SelectShift ™ switch that allows the driver to have control over transmission shifting by manually selecting which gear to operate in.
The selector lever assembly
- locks the transaxle selector lever in the PARK position when the igntion switch is in the LOCK position.
- requires the transaxle selector lever to be in the PARK position to turn the igntion switch to the LOCK position.

Brake Shift Interlock Operation
When the ignition switch is in RUN/START, the solenoid inhibits the selector lever movement (from the PARK position) if the brake pedal is not pressed.
The BSIA inhibits the selector lever movement from the PARK position by mechanically blocking the detent pawl of the selector lever mechanism. When the brake pedal is applied with the ignition key in the RUN/START position and the transmission in PARK, the BSIA is energized by the BCM, this allows the selector lever to be moved out of the PARK position.
| Inputs to BCM | Outputs from BCM |
|---|---|
| Fuse(s) 18 (10A) BPP switch Ignition switch position (RUN/START) | BSIA |
Proper Operation Requirements
Three requirements for the selector lever to be moved from the PARK position are
- Ignition switch in the RUN/START position
- TR sensor in the PARK position
- BPP switch closed (brakes applied - brake lamps on)
Scheme 92
When the selector lever is moved to the M position, the driver can shift the transaxle manually using the SelectShift ™ switch mounted on the selector lever knob. By pressing plus (+) on the toggle switch once will shift the transmission to next highest gear. Pressing the minus (-) on the toggle switch will shift the transmission to next lowest gear.
The SelectShift ™ switch is not serviceable. If a new switch is required, install a new selector lever knob. Refer to Selector Lever Knob .
Component Description
The selector lever cable transfers the transmission operating mode from the selector lever to the automatic transmission. The indicated position of the selector lever is transferred to the transmission through the steering column mounted selector lever, or the floor-mounted selector lever, to the selector lever cable and down to the manual control lever on the transmission.
Normal Operation and Fault Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0815 | The PCM detects a voltage high signal when an upshift is requested | Open or short circuit to the upshift switch |
| P0816 | The PCM detects a voltage high signal when a downshift is requested | Open or short circuit to the downshift switch |
DTC FAULT TRIGGER CONDITIONS
The BSIA system is controlled by the BCM and is activated when the BCM receives a brake pedal applied input.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1319:11 | BSIA system malfunction | Short to ground in the BSIA circuitry. |
DTC FAULT TRIGGER CONDITIONS
The BSIA system is controlled by the BCM and is activated when the BCM receives a brake pedal applied input.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1319:15 | BSIA system malfunction | Short to power or open in the BSIA circuitry. |
