sis
INFOID:0000000009463996
NOTE:
“Start the engine and turn OFF the ignition switch after warm-up.” This is defined as 1 trip.
1 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorize s DTC. In these diagnoses, some illuminate MIL and
some do not. Refer to TM-60, "DTC Index"
.
2 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage. <1
trip>
If the same malfunction is detected again in next drivi ng, TCM memorizes DTC. When DTC is memorized, MIL
lights. <2 trip>
“Trip” of the “2 trip detection diagnosis” indicates the driving mode that executes self-diagnosis during driving.

DIAGNOSIS DESCRIPTION : DTC and DTC of 1st TripINFOID:0000000009463997
2 TRIP DETECTION DIAGNOSIS THAT ILLUMINATES MIL
• The DTC number of the 1st trip is the same as the DTC number.
• When a malfunction is detected at the 1st trip, TCM memo rizes DTC of the 1st trip. MIL does not light at this
stage. If the same malfunction is not detected at t he 2nd trip (conforming to necessary driving conditions),
DTC at the 1st trip is erased from TCM. If the same malfunction is detected at the 2nd trip, TCM memorizes
DTC and MIL lights at the same time.
• The DTC of the 1st trip is specified in Service $01 of SAE J1979/ISO 15031-5. Since detection of DTC at the
1st trip does not illuminate MIL, warning for a problem is not given to a driver.
• For procedure to delete DTC and 1st trip DTC from TCM, refer to TM-43, "CONSULT Function"
.
• If DTC of the 1st trip is detected, it is necessary to check the cause according to the “Diagnosis flow”. Refer
to TM-77, "Flowchart of Trouble Diagnosis"
.
DIAGNOSIS DESCRIPTION : Malf unction Indicator Lamp (MIL)INFOID:0000000009463998
• TCM not only detects DTC, but also sends the MI L signal to ECM through CAN communication. ECM sends
the MIL signal to the combination meter through CAN communication according to the signal, and illumi-
nates MIL.
• For malfunction indicator lamp (MIL) description, refer to EC-74, "DIAGNOSIS DESCRIPTION : Malfunction
Indicator Lamp (MIL)".

RELATION BETWEEN DTC AT 1ST TRIP/DTC/MIL AND DRIVING CONDITIONS (FOR 2 TRIP DE-
TECTION DIAGNOSIS THAT ILLUMINATES MIL)
• When initial malfunction is detected, TCM memorizes DT C of the 1st trip. MIL does not light at this stage.
• If the same malfunction is detect ed at the 2nd trip, TCM memorizes DTC and MIL lights at the same time.
• Then, MIL goes after driving the vehicle for 3 tr ips under “Driving condition B” without malfunction.
• DTC is displayed until 40 trips of “Driving condition A” are satisfied without detecting the same malfunction.
DTC is erased when 40 trips are satisfied.

WARNING CHIME SYSTEM : System DescriptionINFOID:0000000009462880
DESCRIPTION
• The buzzer for the warning chime system is installed in the combination meter.
• The buzzer sounds when the combination meter receives a buzzer output signal from the BCM.

DIAGNOSIS SYSTEM (METER)
DescriptionINFOID:0000000009941189
COMBINATION METER SE LF-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 the ignition switch in ON. Combination meter self-
diagnosis mode will exit upon turning the ignition switch to OFF.
How to Initiate Se lf-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 withi n 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:0000000009941190
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”, potentiall y causing a discharged battery and no-start condition.
APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes shown.
