TROUBLE DIAGNOSIS - GENERAL DESCRIPTION
Revision: 2006 January2006 M35/M45
NP RANGE SW
[ON/OFF]Indicates A/T position indicator lamp signal read from ICC sensor integrated
unit through CAN communication (TCM transmits A/T position indicator
lamp signal through CAN communication).
VHCL SPD AT
[km/h] or [mph]
Indicates vehicle speed calculated from A/T vehicle speed sensor read from
ICC sensor integrated unit through CAN communication (TCM transmits A/
T vehicle speed sensor signal through CAN communication).
GEAR
[1, 2, 3, 4, 5]
Indicates A/T gear position read from ICC sensor integrated unit through
CAN communication (TCM transmits current gear position signal through
CAN communication).
MODE SIG
