Range Selection
| Range Positions | ||
|---|---|---|
| P | Park | In the PARK position, there is no power flow through the transaxle. the parking pawl locks the final drive. the engine may be started. the ignition key may be removed. |
| R | Reverse | In the REVERSE position, the vehicle may be operated in a rearward direction, at a reduced rear ratio. engine braking occurs. |
| N | Neutral | In the NEUTRAL position, the vehicle is able to roll. there is no power flow through the transaxle. the output shaft is not held and is free to turn. the engine may be started. |
| D | Drive position with Grade Assist | DRIVE is the normal position for most forward driving. The DRIVE position provides automatic shifts -1st through 6th gears. maximum fuel economy during normal operation. |
| L | Manual Low | Manual L position allows for 1st gear when the vehicle reaches slower speeds. This position provides maximum engine braking. downshifts to the lowest available gear for the current vehicle speed. |

Gear Availability
MANUAL LEVER POSITION DESCRIPTION CHART MANUAL LEVER POSITION TRANSAXLE GEAR OPERATION DESCRIPTION P Park Forward or reverse gears not available. Final drive is held to the transaxle case. R Reverse Transaxle allows reverse only. N Neutral Forward or reverse gears not available. Final drive moves freely. D 6 forward gears are available. Gears are dependent on vehicle speed and throttle position with coast braking. D Geade Assist 1st through 5th gears are available. Transaxle shifts to 5th gear if button is pressed when the transaxle is in 6th gear. Transaxle provides engine braking. L 1st gears hold with engine braking, the transaxle downshifts to 1st gear when L is selected above a calibrated speed under minimum to moderate accelerator pedal position

- A1 TEST THE BRAKE LIGHTS Apply the brake pedal and view the brake lights. Do the brake lights illuminate? Yes: Go to A2 . No: Refer to «EXTERIOR LIGHTING»(ref-382393) .
- A2 TEST THE BSIA POWER CIRCUIT Disconnect: Selector Lever Harness C3245. Ignition ON. Measure the voltage between selector lever harness C3245-1, circuit CCA26 (BU/GY), vehicle harness side and ground, while applying the brake pedal. Is the voltage greater than 10 volts? Yes: Go to A3 . No: REPAIR circuit CCA26 (BU/GY) for an open.
- A3 TEST THE TCM Ignition OFF. Measure the resistance between selector lever harness C3245-5 circuit GD115 (BK/GY) and ground. Is the resistance less than 5 ohms? Yes: INSTALL a new selector lever. Refer to «SELECTOR LEVER»(ref-382412-S30388105972011012300000) in this information. No: Go to A4 .
- A4 TEST THE BSIA GROUND CIRCUIT Disconnect: Transmission Control Module (TCM) C1ET02. Measure the resistance between selector lever harness C3245-12 and C1ET02-49. Is the resistance less than 5 ohms? Yes: INSTALL a new TCM . No: REPAIR circuit CET53 (BU/OG) for an open.

- B1 TEST THE IC Connect the scan tool. Using the scan tool, monitor the TCS_DEPRES PID while cycling the Transmission Control Switch (TCS). Does the TCS_DEPRES PID cycle from DEPRESSED to NOT DEPRESSED? Yes: Refer to «INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES»(ref-382387) . No: Go to B2 .
- B2 CHECK CJB FUSE 22 (7.5A) Ignition OFF. Check fuse: Central Junction Box (CJB) 22 (7.5A). Is the resistance less than 5 ohms? Yes: Go to B3 . No: Go to B4 .
- B3 CHECK FOR VOLTAGE AT THE SELECTOR LEVER CONNECTOR Disconnect: Selector Lever Harness C3245. Ignition ON. Measure the voltage between selector lever harness C3245-6, circuit CBP22 (GN/OG), vehicle harness side and ground. Is the resistance less than 5 ohms? Yes: Go to B4 . No: REPAIR circuit CBP22 (GN/OG). RECONNECT all components. TEST the system for normal operation.
- B4 TEST THE TCS Measure the resistance between selector lever harness C3245 pins 6 and 7, component side, while cycling the TCS . Is the resistance less than 5 ohms when pressed and greater than 10,000 ohms when released? Yes: Go to B5 . No: INSPECT the selector lever wiring harness for damage. REPAIR the wiring harness as required. If the selector lever wiring harness is not damaged, INSTALL a new selector lever knob.

Brake Shift Interlock Override
Note. If it is necessary to use the brake shift interlock override procedure to move the selector lever out of the PARK position, it is possible that a fuse has blown and the brake lights are not operational. Before driving the vehicle, verify that the brake lights are working.
This vehicle is equipped with a brake shift interlock feature that prevents the selector lever from being moved out of PARK when the ignition is in the ON or RUN position unless the brake pedal is depressed.
Perform the following if the selector lever cannot be moved out of the PARK position when the ignition is in the ON position and the brake pedal is depressed
