DIAGNOSIS SYSTEM (METER)
DescriptionINFOID:0000000009461692
COMBINATION METER SELF-DIAGNOSIS MODE
The following meter functions can be checked during Combination Meter Self-Diagnosis Mode:
• Pointer sweep of speedometer, tachometer and gauges.
• Illumination of all LCD segments and color patterns for meter displays.
• Illumination of all lamps/LEDs that are controlled by the combination meter (regardless of switch status).
STARTING COMBINATION METER SELF-DIAGNOSIS MODE
NOTE:
• Check combination meter power supply and ground circuits if self-diagnosis mode does not start. Refer to
MWI-58, "COMBINATION METER : Diagnosis Procedure"
. Replace combination meter if power supply and
ground circuits are found to be normal and self-diagnosis mode does not start. Refer to MWI-82, "Removal
and Installation".
• Combination meter self-diagnosis mode will function with t he ignition switch in ON. Combination meter self-
diagnosis mode will exit upon turning the ignition switch to OFF.
How to Initiate Self-Diagnosis Mode
1. Press and hold the trip reset switch while turning the ignition switch ON. After 2 seconds release trip reset switch, then press the trip reset switch 3 times within 7 seconds after the ignition switch is turned ON.
2. When the diagnosis function is activated, the meter illuminates all of the following:
• Warning lights/indicators.
• Meter assembly.
• Information display color bars red, green, blue and white (1).
• Odometer, trip A/B odometers and CVT indicator LCD display segments (2).
3. Pressing and holding the trip reset switch performs the pointer sweep test.
CONSULT Function (METER/M&A)INFOID:0000000009461693
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.

POWER CONSUMPTION CONTROL SYSTEM : System DescriptionINFOID:0000000009461600
OUTLINE
• IPDM E/R incorporates a power consumption control function that reduces the power consumption accord-
ing to the vehicle status.
• IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN com-
munication.
Normal mode (wake-up)- CAN communication is normally performed with other control units.
- Individual unit control by IPDM E/R is normally performed.
Low power consumption mode (sleep)- Low power consumption control is active.
- CAN transmission is stopped.
SLEEP MODE ACTIVATION
• IPDM E/R judges that the sleep-ready conditions are fu lfilled when the ignition switch is OFF and none of the
conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica-
tion.
- Front wiper fail-safe operation
- Outputting signals to actuators
- Switches or relays operating
- Auto active test is starting
- Emergency OFF
- Output requests are being received from control units via CAN communication.
• IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep
wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.
WAKE-UP OPERATION
• IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep
wake-up signal (wake up) from BCM or any of the followi ng conditions is fulfilled. In addition, it transmits a
sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start.
- Ignition switch ON
- An output request is received from a control unit via CAN communication.
IGNITION BATTERY SAVER LOGIC
If the ignition is ON for 30 minutes with the engine OFF, the IPDM E/R and BCM turn OFF to save the battery.
