DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions detected by the ECM.
When the ignition switch is turned to the ON position, power is supplied to the MIL circuit, and the ECM
provides the circuit ground which illuminates the MIL.
The MIL operation can be checked visually. When the ignition switch is first turned to the ON position, the
MIL should be illuminated and should then turn off. If the MIL remains illuminated or is not illuminated,
conduct the following troubleshooting procedure using the intelligent tester.

INSPECTION PROCEDURE
(a) Turn the ignition switch to the ON position.
(b) Check the illumination of the MIL.

ADJUSTMENT
HINT:
• On the RH side, use the same procedures as on the LH
side.
• Since a centering bolt is used as door hinge mounting
bolts on the body side and the door side, the door cannot
be adjusted with them on. Substitute a bolt with a washer
for the centering bolt.
1. INSPECT BACK DOOR PANEL SUB-ASSEMBLY
(a) Check that the clearance is within the standard
range.
Standard
2. ADJUST BACK DOOR PANEL SUB-ASSEMBLY
(a) Adjust the door forward / rearward and vertically by
loosening the body side hinge nuts and bolt.
(b) Tighten the body side hinge nuts and bolt after the
adjustment.
Torque: 19.5 N*m (200 kgf*cm, 14 ft.*lbf)
(c) Horizontally and vertically adjust the door by
loosening the door side hinge bolts.
(d) Tighten the body side hinge bolts after the
adjustment.
Torque: 19.5 N*m (200 kgf*cm, 14 ft.*lbf)
(e) Using a screwdriver, remove the back door scuff
plate.
HINT:
Tape the screwdriver tip before use.
