Diagnostic Procedure
1 INSPECTION START
Do you have CONSULT-II?
Yes or No
YescGO TO 2.
NocGO TO 3.
2 CHECK COOLING FAN OPERATION
With CONSULT-II
1. Turn ignition switch ªONº.
2. Perform ªCOOLING FANº in ªACTIVE TESTº mode with CONSULT-II.
SEF646X
3. Make sure that cooling fan-1 operates.
OK or NG
OKcGO TO 12.
NGcGO TO 4.
3 CHECK COOLING FAN OPERATION
Without CONSULT-II
1. Turn ignition switch ªOFFº.
2. Disconnect engine coolant temperature sensor harness connector.
3. Connect 150Wresistor to engine coolant temperature sensor harness connector.
4. Restart engine and make sure that cooling fan operates.
MEC475B
OK or NG
OKcGO TO 12.
NGcGO TO 4.
DTC 0208 OVER HEATZD30DDTi
EC-3007

4 CHECK COOLING FAN POWER SUPPLY CIRCUIT

cRepair open circuit or short to ground or short to power in harness or connectors.
DTC 0208 OVER HEATZD30DDTi
Diagnostic Procedure (Cont'd)
EC-3008

6 CHECK COOLING FAN GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch ªOFFº.
2. Disconnect cooling fan motor-1 harness connector.
SEF691V
3. Check harness continuity between cooling fan relay-1 terminal 5 and cooling fan motor-1 terminal 1, cooling fan relay-1 terminal
7 and cooling fan motor-1 terminal 3, cooling fan motor-1 terminals 2, 4 and body ground. Refer to Wiring Diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
OKcGO TO 7.
NGcRepair open circuit or short to ground or short to power in harness or connectors.
7 CHECK COOLING FAN OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 14 and cooling fan relay-1 terminal 2. Refer to Wiring Diagram.
Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
OKcGO TO 9.
NGcGO TO 8.
8 DETECT MALFUNCTIONING PART
Check the following.
+Harness connectors E127, M21
+Harness connectors M52, F7
+Harness for open or short between cooling fan relay-1 and ECM
cRepair open circuit or short to ground or short to power in harness or connectors.
9 CHECK COOLING FAN RELAY-1

10 CHECK COOLING FAN MOTOR-1
Supply battery voltage between the following terminals and check operation.
SEF645V
MTBL1304
OK or NG
OKcGO TO 11.
NGcReplace cooling fan motor.
11 CHECK INTERMITTENT INCIDENT
Perform ªTROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTº.
cINSPECTION END
12 CHECK COOLING SYSTEM FOR LEAK
Apply pressure to the cooling system with a tester, and check if the pressure drops.
Testing pressure: 98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Higher than the specified pressure may cause radiator damage.
SLC754A
Pressure should not drop.
OK or NG
OKcGO TO 14.
NGcGO TO 13.
