Fail-safe
INFOID:0000000009578957
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.
If No CAN Communication Is Available With ECM
If No CAN Communication Is Available With BCM
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.
NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.
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 second activation and 20 second stop five times.
Control part
Fail-safe operation
Cooling fan
• The cooling fan relay turn ON when the ignition switch is turned ON (Cooling fan HI operation)
• The cooling fan relay turn OFF when the ignition switch is turned OFF
A/C compressor
A/C relay OFF
Generator
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 lamp
• License plate lamp
• Illumination
• Tail lamp
• 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 motor
• 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.
• Returns automatically wiper to stop position when ignition switch is turned ON if fail-safe control
is activated while front wiper motor is operated and wiper stop in the other position than stop
position.

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 Index
INFOID:0000000009578958
NOTE:
The details of TIME display are as follows.
• CRNT: The malfunctions that are detected now
• 1 - 39: The number is indicated when it is normal at present and a malfunction was detected in the past. It
increases like 0
→ 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF → ON. It is
fixed to 39 until the self-diagnosis results are erased if it is over 39. It returns to 0 when a malfunction is
detected again in the process.
