LOWER SEQUENTIAL LEVER SWITCH
NOTESThere must be no present or stored faults.
This indicates the status of the lower sequential lever switch.
This status displays "ACTIVE" with the gear lever in position "M-".
This status displays "INACTIVE" with the gear lever in a position other than "M-".
Check the sequential lever supply on the following connections:
●check for + 12 V on connection AP43 of component 129,
●check for the vehicle earth on connection N of component 129.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the gear lever in position "M", measure the voltage of the following connections:
●check for the vehicle earth on connection 5H of component 129,
●check for the vehicle earth on connection 5FM of component 129.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If any of the measured values is + 12 V, replace the sequential lever.
If the values are 0 V, check that the gear lever positions match the instrument panel display.
If the correct status is not displayed, use the interpretation of fault DF093 "Manual sequential controls circuits".
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.
