Selector Lever Cannot Be Moved From P-Position

CHECKING THE SHIFT-LOCK FUNCTION

Fault Symptom.
Selector lever cannot be moved from position P.

Diagnostic Procedure.
1. Remove the shift-lock relay which is fitted in the distribution center under the facia in the passenger compartment. Check the relay's ground connection and remedy any faults.
Connect a volt meter as follows: relay socket, pin 31 -- BATT- < 0.1 V.

2. Check the relay's inputs from the gear position sensor and remedy any faults.
Connect a volt meter to the relay socket as follows with the ignition switched ON:
^ pin B - pin 31,
^ pin C - pin 31,
and operate the selector lever.

Nominal voltages are in accordance with the following table.

Nominal Voltage Table:

Diagnostic trouble code P0705 is often recorded when there is a fault in connections B and C. CHECK GEARBOX is lit and the system's emergency program is activated.





3. Check the relay's input from the brake light switch and remedy any faults. Connect a voltmeter to the relay socket as follows with the ignition switched on: pin R - pin 31, and depress the brake pedal.
A non-depressed brake pedal should result in battery positive voltage.
A depressed brake pedal should result in <0.5 V.

If the measurement result is wrong, check:
- fuse 9 and power supply to the fuse.
- brake light switch. It might have to be adjusted or a new one fitted.
- the wiring.

NOTE: If fuse 9 is removed the starting motor interlock function is prevented from operating, which means that the selector lever can be operated.





4. Check the functioning of the lifting magnet. Connect alternately BATT+ and BATT- or ground to the relay socket, pin 87.
BATT+ should result in activation of the lifting magnet and BATT- or ground in the lifting magnet falling.

If the measuring works and steps 1-3 have been carried out, install a new shift-lock relay.

If the measuring does not work, go to step 5.

5. Check the lifting magnet and its wiring and remedy any faults. The lifting magnet is located in the selector lever housing. Disconnect the lifting magnet's connector.
Connect a voltmeter to the female connector as follows:
^ pin 2 - BATT- < 0.1 V
^ pin 1 - pin 2 BATT+ with non-depressed brake pedal
<0.5 V with depressed brake pedal.

If the measurement results are correct, install a new lifting magnet.

If the measurement results are wrong, install a new shift-lock relay.

6. If it still does not function after steps 1-5 have been carried out, carry on with mechanical fault tracing of the lifting magnet.
