DIAGNOSIS SYSTEM (IPDM E/R)
Diagnosis DescriptionINFOID:0000000012542533
AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
• When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation se-
quence Inspection location
Operation
1 Front wiper LO for 5 seconds → HI for 5 seconds
2 •Parking lamp
• Side marker lamp

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000012430674
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped into vehicl es, and each control unit shares information and links
with other control units during operation. With CAN co mmunication, control units are connected with two com-
munication lines (CAN-H line, CAN-L line) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-30, "
CAN
COMMUNICATION SYSTEM : CAN Communication Signal Chart".

DTC CONFIRMATION PROCEDURE
1.PERFORM SELF-DIAGNOSIS
1. Turn ignition switch ON and wait for 7 seconds or more.
2. Using CONSULT, perform SELF-DIAGNOSIS RESULTS of AIR BAG.
3. Check if any DTC is displayed in the self-diagnosis results.
Is DTC detected?
YES >> Refer to SRC-94, "Diagnosis Procedure".
NO >> Refer to GI-42, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000012430676
1.CHECK CAN COMMUNICATION SYSTEM
Check CAN communication system. Refer to LAN-16, "
Trouble Diagnosis Flow Chart".

5. Remove screws (A), then release pawls and remove spiral cable and steering angle sensor (1) as an assembly.
: Pawl
CAUTION:
Do not turn the spiral cable quickly or beyond the limit
number of turns (approximately 2.5 turns from the neutral
position), this may cause the cable to snap.
6. Remove screws (A), then release pawls (B) and separate the steering angle sensor (2) from spiral cable (1).
CAUTION:
Do not reuse steering angle sensor.
CAUTION:
• Do not strike or drop the spiral cable.
• Replace the spiral cable if it has been dropped or sustained
an impact.
INSTALLATION
Installation is in the reverse order of removal.
• The turn signal lever must be in the neutral position for spiral cable installation.

• When the selector lever is in the P or N position, power is supplied to starter relay and starter control relay by
the transmission range switch. The BCM and IPDM E/R (C PU) will detect the selector lever position by the
input signal.
• When the starter operating condition is met, the IPDM E/R will turn the starter control relay ON by starter
control relay control signal.
• When engine cranking condition is met, the BCM turns ON the starter relay by starter control relay signal.
• Then battery power is supplied to starter motor (“S” terminal) through the starter control relay and starter
relay.
