(See MANUAL TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION [D66M-R].) (See MANUAL TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION [F66M-R].)
(6)  Selector lever knob (ATX) (See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
(7)  Shift panel (See SHIFT PANEL REMOVAL/INSTALLATION.)
(8)  Front console box (See FRONT CONSOLE BOX REMOVAL/INSTALLATION.)
(9)  CD player (with CD player) (See CD PLAYER REMOVAL.) (See CD PLAYER INSTALLATION.)
(10)  DVD/CD player (with DVD/CD player) (See DVD/CD PLAYER REMOVAL.) (See DVD/CD PLAYER INSTALLATION.)
(11)  Side wall (See SIDE WALL REMOVAL/INSTALLATION.)
(12)  Front console (See FRONT CONSOLE REMOVAL/INSTALLATION.)
(13)  Climate control unit (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].) (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)

3.  Reconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].)

4.  Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

•  If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
―  If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the indicator unit. (See INDICATOR UNIT REMOVAL/INSTALLATION.)

LED Illumination Inspection


When using M-MDS

1.  Connect the M-MDS to the DLC-2.

2.  After vehicle identification, select the following from the M-MDS initialization screen.

1.  "Data logger"
2.  "Module"
3.  "IC"

3.  Using "LCD_SEG", verify that the following warning/indicator lights are turned on.

•  If any one of the warning/indicator lights is not displayed, replace the indicator unit. (See INDICATOR UNIT REMOVAL/INSTALLATION.)


When not using M-MDS

1.  Switch the ignition ON (engine off or on).

2.  Using a jumper wire, connect indicator unit terminal G and body ground for 5 s or more.

Caution
•  If the terminals are mistakenly connected, vehicle damage or fire could occur. When connecting with the jumper wire, thoroughly verify what terminals are being connected to prevent a miss-connection.

3.  Verify that the following warning/indicator lights are turned on.
