2.2.7.44 Engine Fault Lamp (MIL)/Check Vehicle Lamp Malfunction

Description:

CAN network is used in vehicles. Fault lamps are controlled via the instrument panel circuit. When ECM DTC code is set to light
fault lamps, ECM sends a "Light the fault lamp" signal through the CAN network the instrument panel. The instrument panel internal
circuit light the fault lamp indicating engine fault after receiving the instruction from ECM.

Diagnostic Steps:

Step 1

Check other fault lamps in the instrument cluster.

(a)

Turn the ignition switch to "ON" position.

Other fault lamps normal?

Yes

Go to step 3

No

Step 2

Repair instrument cluster circuits.

(a)

Repair instrument cluster power supply circuit. Refer to

11.7.6.7

 

DTC U129C U129D

(b)

Repair instrument cluster ground circuit. Refer to

11.7.6.7

 

DTC U129C U129D

.

Fault solved?

Yes

System normal

No

Step 3

Check the instrument DTC codes.

(a)

Connect scan tool.

(b)

Turn the ignition switch to "ON" position.

(c)

Scan instrument DTC.

Is there DTC U1430?

Yes

Go to step 5

No

Step 4

Test the fault indicator lamp.

(a)

Connect scan tool.

(b)

Turn the ignition switch to "ON" position.

(c)

Select on the scan tool "Fault indicator lamp test" menu within
the "Function Test".

Is the fault indicator lamp lit?

Yes

Go to step 6

No

Step 5

Replace the instrument cluster.

(a)

Turn off the ignition switch and remove the ignition key.

(b)

Disconnect the battery negative cable.

(c)

Replace the instrument cluster. Refer to 

11.7.7.1
