ECM BRANCH LINE CIRCUIT
Diagnosis ProcedureINFOID:0000000001333707
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-
nector side).
-ECM
- Harness connector E7
- Harness connector M69
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair the terminal and connector.
2.CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of ECM.
2. Check the resistance between the ECM harness connector terminals.
- Diesel engine models
- Gasoline engine models
Is the measurement value within the specification?
YES >> GO TO 3.
NO >> Repair the ECM branch line.
3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ECM. Refer to the following.

PERIODIC MAINTENANCE
Periodic MaintenanceINFOID:0000000001277598
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE (MR ENGINE)
(Annual Mileage <30,000 Km/year)
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace, [ ] = At the specified mileage only.
NOTE:
 Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving Con-
ditions”.
(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
(2) Replace the drive belt if found damaged.
(3) First replace at 90,000 Km (54,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform "I" (Check-
ing the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.
(5) Perform only according to “Maintenance Under Severe Driving conditions” for models without Euro-OBD system. For
models with Euro-OBD system, periodic maintenance is not required.
