BODY – Sunroof42-11
Inspection Procedure 2
The motor does not reverse its direction when a load of
140 N or more is applied while the sunroof is closing.
Probable cause
The sunroof-ECU monitors the load conditions from the amount of current flowing
to the motor. If more than the constant amount of current is flowing, the direction
of motor operation is reversed to prevent jamming.
If the motor does not reverse direction even when an excessive load is being applied,
the cause may be a malfunction of the sunroof-ECU.
Malfunction of sunroof-ECU
Replace the sunroof-ECU.
Inspection Procedure 3
The timer does not operate for 30 seconds after the
ignition switch is turned to OFF.
Probable cause
The sunroof-ECU has a timer function which operates for 30 seconds after the ignition
switch is turned to OFF. If the timer does not operate, the cause may be a malfunction
of the sunroof-ECU or of the wiring harness or connector.
Malfunction of sunroof-ECU

Malfunction of wiring harness or connector

Inspection Procedure 4
Opening or closing of the sunroof is possible for 30
seconds after turning the ignition switch to OFF, but the
timer function is not extended when the driver’s side door
is opened within this period.
Probable cause
The sunroof timer operation period is extended when an on signal is output from
the driver’s-side door switch. Because of this, if the timer operation period is not
extended, the cause may be a malfunction of the door switch input circuit.

CAUTION

Carefully read and observe the information in the SERVICE PRECAUTIONS (P.52B-3.) prior to any service.

For information concerning troubleshooting or maintenance, always observe the procedures in the Troubleshooting
(P.52B-6.) section.

If any SRS components are removed or replaced in connection with any service procedures, be sure to follow the
procedures in the INDIVIDUAL COMPONENT SERVICE section (P.52B-22.) for the components involved.

If you have any questions about the SRS, please contact your local distributor.

SRS – General Information52B-2
GENERAL INFORMATION
To improve safety, the SRS is available as optional
part.
The SRS consists of two air bag modules, SRS
air bag control unit (SRS-ECU), SRS warning lamp
and clock spring. One air bag is located in the
centre of the steering wheel and another above
the glove box. Each air bag has a folded air bag
and an inflator unit. The control unit under the floor
console monitors the system and has a safing G
sensor and an analog G sensor. The warning lamp
on the instrument panel indicates the operationalstatus of the SRS. The clock spring is installed
in the steering column.
Only authorized service personnel should do work
on or around the SRS components. Those service
personnel should read this manual carefully before
staring any such work. Extreme care must be used
when servicing the SRS to avoid injury to the service
personnel (by inadvertent deployment of the air
bags) or the driver (by rendering the SRS
inoperative).
