DTC INSPECTION [EVP CONTROL UNIT]
id040251837000
CMDTC self test
1. Connect the M-MDS to the DLC-2.
2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.
3. Verify the DTC according to the directions on the screen.
4. After completion of repairs, clear all DTCs stored in the module. (See CLEARING DTC [EVP CONTROL UNIT].)

Instrument cluster power supply
|
• The EVP control unit constantly receives the power supply voltage value of the instrument cluster sent via CAN signal from the instrument cluster.
• If a DTC is detected, the EVP control unit records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the M-MDS.

|
IG-ON_TIMER
|
hh:mm:ss*1
|
Elapsed time since ignition was switched ON
|
• The EVP control unit constantly receives the elapsed time since the ignition was switched ON sent via CAN signal from the instrument cluster.
• If a DTC is detected, the EVP control unit records the elapsed time since the ignition was switched ON when the DTC was detected, and it is displayed in the M-MDS.

|
• Key Out: Ignition switched off
• Key Recently Out (Position 0): Elapsed time within 3 s since ignition was switched off
• Accessory (Position 1): Ignition is switched to ACC
• Post Ignition (Position 2): Elapsed time within 3 s since ignition was switched ON
• Ignition On (Position 2): Ignition switched ON (engine off)
• Running (Position 2): Ignition switched ON (engine on)
• Running - Starting: Cranking condition
|
• The EVP control unit constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
• If a DTC is detected, the EVP control unit records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.

TOTAL_DIST
|
km, ft, mi
|
Accumulated total traveled distance from completion of vehicle until EVP control unit detects DTC (Odometer value in instrument cluster)
|
The distance traveled when the EVP control unit detected a DTC can be calculated by performing the following procedure.
1. Verify the odometer value in the instrument cluster.
2. Verify the snapshot data item TOTAL_DIST.
3. Subtract 2 from 1.
|

|
|
TOTAL_TIME
|
hh:mm:ss*1
|
Accumulated total elapsed time since vehicle completion until EVP control unit detects a DTC
|
The elapsed time when the EVP control unit detected a DTC can be calculated by performing the following procedure.
1. Verify the PID item TOTAL_TIME of the instrument cluster.
2. Verify the snapshot data item TOTAL_TIME.
3. Subtract 2 from 1.
