Diagnostic Procedure

Step

Inspection

Action
1
VERIFY PCM DTCs
•  Retrieve the PCM DTCs using the M-MDS.
•  Are any DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [PCM (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].)
No
Without i-ELOOP:
•  Go to Step 4.
With i-ELOOP:
•  Go to the next step.
2
VERIFY DC-DC CONVERTER (I-ELOOP) DTCs
•  Retrieve the DC-DC converter (i-ELOOP) DTCs using the M-MDS.
•  Are any DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [i-ELOOP].)
No
Go to the next step.
3
INSPECT DC-DC CONVERTER (i-ELOOP)
•  Inspect the DC-DC converter (i-ELOOP).
•  Is the DC-DC converter (i-ELOOP) normal?
Yes
Go to the next step.
No
Replace the DC-DC converter (i-ELOOP), then go to Step 6.
(See DC-DC CONVERTER (i-ELOOP) REMOVAL/INSTALLATION [i-ELOOP].)
4
INSPECT BATTERY
•  Inspect the battery.
•  Is the battery normal?
Yes
Go to the next step.
No
Replace the battery, then go to Step 6.
(See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)
5
INSPECT GENERATOR
•  Inspect the generator.
•  Is the generator normal?
Yes
Go to the next step.
No
Replace the generator, then go to the next step.
(See GENERATOR REMOVAL/INSTALLATION [WITHOUT i-ELOOP (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].)
(See GENERATOR REMOVAL/INSTALLATION [WITH i-ELOOP (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].)
6
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Clear the auto leveling control module DTCs using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 5 s or more.
•  Retrieve the auto leveling control module DTCs using the M-MDS.
•  Is the same Pending DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the auto leveling control module, then go to the next step.
No
Go to the next step.
7
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [AUTO LEVELING CONTROL MODULE].)
No
DTC troubleshooting completed.
