IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status • CAN communication is normally performed with other control units.
• Individual unit control by IPDM E/R is normally performed.
• When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status • Process to stop CAN communication is activated.
• All systems controlled by IPDM E/R are stopped. When 1 second has elapsed after CAN communica-tion with other control units is st opped, mode switches to sleep status.
3. Sleep status • IPDM E/R operates in low current-consumption mode.
• CAN communication is stopped.
• When a change in CAN communication signal is detec ted, mode switches to CAN communication sta-
tus.
• When a change in ignition switch signal is detected, mode switches to CAN communication status.
CAN Communication System DescriptionINFOID:0000000005395355
Refer to LAN-7, "System Diagram".
Function of Detecting I gnition Relay MalfunctionINFOID:0000000005395356
• When the integrated ignition relay is stuck in a "closed contact" position and cannot be turned OFF, IPDM E/
R turns ON tail and parking lamps for 10 minutes to indicate IPDM E/R malfunction.
• When the state of the integrated ignition relay does not agree with the state of the ignition switch signal
received via CAN communication, the IPDM E/R activates the tail lamp relay.
NOTE:
When the ignition switch is turned ON, the tail lamps are OFF.

ACTIVE TEST
Display Item List
Auto Active TestINFOID:0000000005395358
DESCRIPTION
• In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
- Rear window defogger
- Front wipers
- Tail, license and parking lamps
- Daytime lamp system (Canada only)
- Front fog lamps
- Headlamps (High, Low)
- A/C compressor (magnet clutch)
- Cooling fan
OPERATION PROCEDURE
1. Close hood and front door RH, and lift wiper arms away from windshield (to prevent glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, pres s front door switch LH 20 times. Then turn ignition
switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once.
6. After a series of operations is repeated three times, auto active test is completed.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Concept of Auto Active Test
• IPDM E/R actuates auto active test mode when it re ceives door switch signal from BCM via CAN communi-
cation line. Therefore, when auto active test mode is activated successfully, CAN communication between
IPDM E/R and BCM is normal.
• If any of the systems controll ed by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

CAUTION:
• Do not allow axial impact to steering colu mn assembly during removal and installation.
• Steering column must be kept at maximum tilt up position during removal and installation. Do not
operate tilt mechanism while steeri ng column is out of the vehicle.
• Put matching mark on intermediate shaft and st eering column assembly before removing intermedi-
ate shaft.
• When steering wheel is turned re peatedly with the vehicle stopped, care must be taken because
motor and EPS control unit may get too hot.
• Steering column assembly is heavy. Care must be taken when removing steering column assembly
from vehicle.
• Do not put steering column assem bly near the things that generate excessive magnetic force.
• Steering column assembly (with motor, reduc tion gear, sensor) cannot be disassembled.
• Any time the ignition switch h as been removed and installed, the keys must be re-registered in the
BCM. Refer to CONSULT–III ope ration manual IVIS/NVIS.
REMOVAL
1. Set front wheels to straight ahead-position.
2. Remove spiral cable. Refer to SRS-37
.
3. Remove instrument lower finisher. Refer to IP-11, "
Component Parts".
4. Disconnect each switch connector installed to steering column assembly, and then disconnect harness from steering column assembly.
5. Remove bolt of intermediate shaft (upper side), and then remove intermediate shaft from steering column assembly.
