A/T INDICATOR
System DescriptionINFOID:0000000001328470
A/T shift position is displayed in the s egment display in the combination meter.
MANUAL MODE
 Unified meter and A/C amp. reads manual mode signal and shift-up/down signal from A/T device (manual
mode switch), and transmits the signals to TCM with CAN communication.
 TCM processes manual mode signal and shift-up/down signal, and transmits manual mode indicator signal and shift position indicator signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits manual mode indicator signal and shift position indicator signal to
combination meter with the communication line.
 Combination meter indicates shift gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position indicator signal.
NOT MANUAL MODE
 Unified meter and A/C amp. reads not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication.
 TCM transmits shift position indicator signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits shift position indicator signal to combination meter with the communi- cation line.
 Combination meter indicates A/T shift position when receiving shift position indicator signal.

2. Select “AUTO AIM”.
3. Confirm following.
a. The target should be accurately placed.
b. The vehicle should be stopped.
4. Select “Start” to perform aiming.
CAUTION:
Never Select “Start” when the target is not placed.
5. Input “Dh”, and then select “Start”. NOTE:
Check the value “Dh”. Refer to "VEHICLE HEIGHT CHECK".
CAUTION:
Never change “Ht” and “Dt”.
6. Check it display item.
a. “Normally Completed” is displayed, then selecting “Completion”.
b. Perform the following services when displa yed “SUSPENSION” or “ABNORMALLY COMPLETED”.
NOTE:
Replace camera unit if “SUSPENSION” is repeatedly indicated though the above tw o service is performed.
7. Check if “Normally Completed” is displayed and close the aiming adjustment procedure by selecting
“End”.
Check After The Adjustment
1. Perform self-diagnosis of LDW camera unit. Refer to DI-81, "CONSULT-III Function (LDW)".
2. Test the LDW system operation by running test. Refer to DI-71, "
Action Test".
