DIAGNOSIS AND REPAIR WORKFLOW

Work Flow

INFOID:0000000000892243

DETAILED FLOW

1.

OBTAIN INFORMATION ABOUT SYMPTOM

Interview the customer to obtain as much information as possible about the conditions and environment under
which the malfunction occurred.

>> GO TO 2.

2.

CHECK SYMPTOM

• Check the symptom based on the information obtained from the customer.
• Check if any other malfunctions are present. 

>> GO TO 3.

3.

CHECK ON BOARD DIAGNOSIS OPERATION

Check that the on board diagnosis function operates. Refer to 

MWI-21, "Diagnosis Description"

.

Does the on board diagnosis function operate normally?

YES

>> GO TO 4.

NO

>> Repair or replace the malfunctioning part and go to 6.

4.

CHECK CONSULTIII SELF-DIAGNOSIS RESULTS

Connect CONSULT-III and perform self-diagnosis. Refer to 

MWI-23, "CONSULT-III Function (METER/M&A)"

.

Are self-diagnosis results normal?

YES

>> GO TO 5.

NO

>> Repair or replace the malfunctioning part and go to 6.

5.

NARROW DOWN THE MALFUNCTIONING PART BY SYMPTOM DIAGNOSIS

Perform symptom diagnosis and repair or replace the identified malfunctioning parts.

>> GO TO 6.

6.

FINAL CHECK

Check that the combination meter operates normally.

Does it operate normally?

YES

>> INSPECTION END

NO

>> GO TO 1.

METER SYSTEM : System Description

INFOID:0000000000892245

COMBINATION METER

• The combination meter receives the information required to control the operation of each gauge, indicator/

warning lamp, and information display via CAN communication from each unit, each switch, and sensor. 

• The combination meter incorporates a trip computer that displays messages on the information display

according to the information received from various units. 

• The combination meter incorporates a buzzer function that sounds an audible alarm with the integrated

buzzer device. Refer to 

WCS-4, "WARNING CHIME SYSTEM : System Description"

 for further details.

• The combination meter integrates the meter circuit check function and the segment check function that

checks the information display operation.

IPDM E/R

• IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch signal to

the combination meter via BCM with CAN communication.

• IPDM E/R is equipped with the diagnosis function. It can perform the operation check of oil pressure warning

lamp with the auto active test and the diagnosis with CONSULT-III.
