TRANSAXLE RANGE (TR) SWITCH INSPECTION [LA4AX-EL (CD4E)]

Operating Inspection

1. Verify that the starter operates only when the ignition switch is turned to the START position with the selector lever in P or N position.

• If there is any malfunction, adjust the TR switch. (See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [LA4AX-EL (CD4E)].)

2. Verify that the back-up lights illuminate when shifted to the R position with the ignition switch in the ON position.

• If there is any malfunction, adjust the TR switch. (See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [LA4AX-EL (CD4E)].)

3. Verify that the positions of the selector lever and the indicator match.

• If there is any malfunction, adjust the TR switch. (See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [LA4AX-EL (CD4E)].)

Continuity Inspection

Caution

• Liquid or foreign material penetrating the TR switch connector can cause a poor connection or corrosion. Be sure not to spill liquid or foreign material on the connector when disconnecting it.

1. Disconnect the negative battery cable.

2. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [YF (2.0L Zetec)].) (See BATTERY REMOVAL/INSTALLATION [L3, AJ (3.0L Duratec)].)

3. Disconnect the crankcase vent hose and MAF sensor connector.

4. Remove the air hose and air cleaner cover.

5. Remove the air cleaner component.

6. Remove the thermostat housing. (See THERMOSTAT REMOVAL/INSTALLATION [YF (2.0L Zetec)].) (See THERMOSTAT REMOVAL/INSTALLATION [AJ (3.0L Duratec)].)

Note

• The thermostat housing must be removed to access the TR switch.

7. Disconnect the TR switch connector.

8. Measure the continuity and resistance between the following terminals.

• If there is any malfunction, adjust the TR switch. (See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [LA4AX-EL (CD4E)].)

Standard value

9. Remeasure the continuity and resistance between the terminals.

• If there is any malfunction, replace the TR switch. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL [LA4AX-EL (CD4E)].) (See TRANSAXLE RANGE (TR) SWITCH INSTALLATION [LA4AX-EL (CD4E)].)

10. Connect the TR switch connector.

11. Install the thermostat housing. (See THERMOSTAT REMOVAL/INSTALLATION [YF (2.0L Zetec)].) (See THERMOSTAT REMOVAL/INSTALLATION [AJ (3.0L Duratec)].)

12. Install the air cleaner component.

13. Install the air hose and air cleaner cover.

14. Connect the crankcase vent hose and MAF sensor connector.

15. Verify that there is no blockage or kinks, and the vent hose routing is correct.

16. Install the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [YF (2.0L Zetec)].) (See BATTERY REMOVAL/INSTALLATION [L3, AJ (3.0L Duratec)].)

17. Connect the negative battery cable.

Note

• If the battery has been disconnected then reconnected, the vehicle may need to be driven 160 km {100 miles} or more for the PCM to relearn the control strategy.
