System DescriptionINFOID:0000000003533096
OUTLINE
Electric sunroof system consists of
• Front door switches
• Sunroof switch
• Sunroof motor assembly
• BCM (body control module)
BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.
OPERATION
Power is supplied at all times
• through 50A fusible link (letter f, located in the fuse and fusible link box)
• to BCM terminal 70 and
• through BCM terminal 69
• to sunroof motor assembly terminal 5.
With ignition switch in ON or START position, power is supplied
• through 10A fuse (No. 59, located in the fuse and relay box)
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67 and
• to sunroof motor assembly terminal 7
• through grounds M57, M61 and M79.
TILT UP OPERATION
When the tilt switch is operated for tilt up, ground is supplied
• to sunroof motor assembly terminal 4

TROUBLE DIAGNOSES FOR SYMPTOMS
Load Leveling Rear Air Suspension System Does Not OperateINFOID:0000000003532667
1.CHECK WARNING LAMP ACTIVATION
Make sure warning lamp remains off while driving.
OK or NG
OK >> GO TO 2.
NG >> Carry out self-diagnosis. Refer to RSU-11, "
CONSULT-II Function (AIR LEVELIZER)" .
2.CHECK FUSES AND FUSIBLE LINK
Check that the following fuses and fusible link are not blown.
OK or NG
OK >> GO TO 3.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link.
3.CHECK SUSPENSION CONTROL UNIT POWER AND GROUND
1. Turn the ignition switch ON.
2. Check voltage between suspension control unit connector B3
terminal 6 and ground and between suspension control unit con-
nector B3 terminal 7 and ground.
3. Turn the ignition switch OFF.
4. Check continuity between suspension control unit connector B3
terminal 16 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4.CHECK GENERATOR SIGNAL INPUT
1. Start the engine.

System DescriptionINFOID:0000000003533319
Power is supplied at all times
• through 40A fusible link (letter m , located in the fuse and fusible link box)
• to ignition switch terminal B.
With the ignition switch in the START position, power is supplied
• from ignition switch terminal ST
• to IPDM E/R terminal 21.
With the ignition switch in the ON or START position, power is supplied to IPDM E/R (intelligent power distribu-
tion module engine room) CPU.
With the selector lever in the P or N position, power is supplied
• through A/T assembly terminal 9
• to IPDM E/R terminal 48.
Ground is supplied at all times
• to IPDM E/R terminals 38 and 59
• through body grounds E9, E15 and E24.
Then the starter relay is turned on.
The IPDM E/R is energized and power is supplied
• from terminal 19 of the IPDM E/R
• to terminal 1 of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The
starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates.

DIAGNOSTIC PROCEDURE 1
Check Starter Motor Circuit
1.CHECK POWER SUPPLY TO STARTER MOTOR
1. Remove the fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn the ignition switch OFF.

4. Check that the starter motor connector F27 connection is clean and tight.
5. Check voltage between starter motor connector F27 terminal 2
and ground using a digital circuit tester.
OK or NG
OK >> GO TO 2.
NG >> Check harness between the battery and the starter
motor for open circuit.
2.CHECK VOLTAGE DROP ON STARTER MOTOR CIRCUIT
Check voltage between starter motor connector F27 terminal 2 and
battery positive terminal using a digital circuit tester.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter
motor for poor continuity.
3.CHECK VOLTAGE DROP ON STARTER MOTOR GROUND CIRCUIT
Check voltage between starter motor case and battery negative ter-
minal using a digital circuit tester.
OK or NG
OK >> Starter motor ground circuit is OK. Further inspection is
necessary. Refer to "WORK FLOW" .
NG >> Check harness between the starter motor case and
ground for poor continuity.
DIAGNOSTIC PROCEDURE 2
Check Magnetic Switch Circuit
1.CHECK POWER SUPPLY FOR MAGNETIC SWITCH
1. Remove the fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn the ignition switch OFF.
4. Disconnect starter motor connector F28.
5. Check voltage between starter motor connector F28 terminal 1
and ground using a digital circuit tester.
OK or NG
OK >> GO TO 2.
NG >> Check the following.
• 40A fusible link (letter m , located in fuse and fusible
link box)
• Ignition switch Battery voltage should ex-
ist.
