Preliminary CheckBIS0012P
SETTING CHANGE FUNCTION
The settings of the automatic driving positioner system can be changed, using CONSULT-II.
×: Applicable –: Not applicable
It is possible to set sliding driver seat for entry/exit of vehicle by pressing set switch.
NOTE:
After the setting is registered, the new setting is effective, even if the battery is disconnected.
CHECK POWER SUPPLY AND GROUND
1. CHECK FUSE
Check if any of the following fuses in the BCM are blown.

Check 50A fusible link (letter M , located in the fuse and fusible link box.)

Check 15A fuse [No.17, located in the fuse block (J/B)]

Check 10A fuse [No.1, located in the fuse block (J/B)]

Check 10A fuse [No.6, located in the fuse block (J/B)]
NOTE:
Refer to SE-16, "
Component Parts and Harness Connector Location" .
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
3, "POWER SUPPLY ROUTING CIRCUIT" .

2. CHECK POWER SUPPLY CIRCUIT (BCM)
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open and short between BCM and
fuse or fusible link.
3. CHECK GROUND CIRCUIT (BCM)
1. Turn ignition switch OFF.
2. Check continuity between BCM connector M4 terminal 52 and
ground.
OK or NG
OK >> BCM circuit is OK. Check the driver seat control unit.
GO TO 4.
NG >> Repair or replace the harness between BCM and
ground.
4. CHECK FUSE
Check 10A fuse [No.9, located in fuse block (J/B)].
NOTE:
Refer to SE-16, "
Component Parts and Harness Connector Location" .
OK or NG
OK >> GO TO 5.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
