GEAR LEVER POSITION
STATUS
DEFINITIONThis status ET012 indicates one of the six positions of the gear lever: UP, DW, N, R,
STB or A.
NOTESNone
Engine stopped, ignition on
Check the specification of status ET012 for each position of the gear lever:
●movement towards the front of the vehicle: "UP".
●movement towards the rear of the vehicle: "DW".
●Movement to the right: "N".
●Movement to the left: "A".
●Brake pedal depressed, movement to the right followed by a movement to the rear: "R".
●Lever in rest position: "STB".
If status ET012 is not consistent with the position of the gear lever each time it is moved, refer to the interpretation
of fault DF067 "Lever position switch circuit".
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.

GEAR ENGAGED
STATUS
DEFINITIONThis status ET013 indicates the gear engaged and corresponds to the gear displayed
on the instrument panel:
●1: 1st
●
2: 2nd
●
3: 3rd
●
4: 4th
●
5: 5th
●
N: Neutral
●R: Reverse
NOTESNone
Engine stopped, ignition on
Check the specification of status ET013 each time the gear lever is moved:
●Gears 1st to 5th: push the lever forwards for the next gear up and backwards for the next gear down and
check how status ET013 changes each time the gear lever moves.
●Position N (neutral): when status ET013 is "1", push the lever to the right and check that status ET013 is
"N".
●Gear R (reverse): check status ET013 changes to "R" after depressing the brake pedal, pushing the lever to
the right and then to the rear.
If status ET013 is not correct, refer to the interpretation of faults DF069 "Selection position circuit" and DF070
"Engaging position sensor circuit".
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
