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.
APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes shown.
