CAN COMMUNICATION CONTROL
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.
Control part Fail-safe operation
Cooling fan Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is
turned ON (Cooling fan operates at HI)
 Turns OFF the cooling fan relay-1, the cooling fan relay-2 and the cooling fan relay-3
when the ignition switch is turned OFF (Cooling fan does not operate)
A/C compressor A/C relay OFF
Alternator Outputs the power generation command signal (PWM signal) 0%
Control part Fail-safe operation
Headlamp Turns ON the headlamp low relay when the ignition switch is turned ON
 Turns OFF the headlamp low relay when the ignition switch is turned OFF
 Headlamp high relay OFF
Parking lamps
 License plate lamps
 Illuminations
 Tail lamps Turns ON the tail lamp relay when the ignition switch is turned ON
 Turns OFF the tail lamp relay when the ignition switch is turned OFF
Front wiper The status just before activation of fail-safe control is maintained until the ignition
switch is turned OFF while the front wiper is operating at LO or HI speed.
 The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-
safe control is activated while the front wiper is set in the INT mode and the front wiper
motor is operating.
Front fog lamps Front fog lamp relay OFF
Horn Horn OFF
Ignition relay The status just before activation of fail-safe is maintained.

NOTE:
This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item
“WIP PROT” while the wiper is stopped.
STARTER MOTOR PROTECTION FUNCTION
IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains
active for 90 seconds.
DTC IndexINFOID:0000000003880882
NOTE:
 The details of time display are as follows.
- CRNT: A malfunction is detected now
- PAST: A malfunction was detected in the past.
 IGN counter is displayed on FFD (Freeze Frame data).
- The number is 0 when is detected now
- The number increases like 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF →
ON.
- The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

SYMPTOM DIAGNOSIS
POWER DISTRIBUTION SYSTEM
Symptom TableINFOID:0000000003805778
The engine start function, door lock function, power distribution system and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding control. Narrow down the functional area in question
by checking the following table to identify which function is malfunctioning. The vehicle security function can
operate only when the door lock and power distribution system are operating normally. Therefore, it is easy to
identify any factor unique to the vehicle security system by checking the following table.
Use the chart below to help you find the cause of the symptom. The numbers indicate the order of the inspec-
tion.
NOTE:
Before starting vehicle security system operation check, the following conditions must be met.
 Open front windows
 Turn ignition switch OFF
 Pull out Intelligent Key from key slot.
