POWER SUPPLY AND GROUND CIRCUIT

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureBBS004YP
1. INSPECTION START
Start engine.
Is engine running?
Ye s o r N o
Yes >> GO TO 8.
No >> GO TO 2.
2. CHECK ECM POWER SUPPLY CIRCUIT-I
1. Turn ignition switch OFF and then ON.
2. Check voltage between ECM terminal 109 and ground with
CONSULT-II or tester.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING PART
Check the following.

Fuse block (J/B) connector M1

10A fuse

Harness for open or short between ECM and fuse
>> Repair open circuit or short to ground or short to power in harness or connectors.

DTC P0327, P0328 KS

DTC P0327, P0328 KSPFP:22060
Component DescriptionBBS0050N
The knock sensor is attached to the cylinder block. It senses engine
knocking using a piezoelectric element. A knocking vibration from
the cylinder block is sensed as vibrational pressure. This pressure is
converted into a voltage signal and sent to the ECM.
On Board Diagnosis LogicBBS0050O
The MI will not light up for these diagnoses.
DTC Confirmation ProcedureBBS0050P
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and run it for at least 5 seconds at idle speed.
3. If 1st trip DTC is detected, go to EC-514, "
Diagnostic Procedure"
.
WITHOUT CONSULT-II
1. Start engine and run it for at least 5 seconds at idle speed.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to EC-514, "
Diagnostic Procedure" .

OK or NG
OK >> GO TO 8.
NG >> Repair open circuit or short to power in harness or con-
nectors.
8. CHECK COOLING FAN MOTOR-2 CIRCUIT-II FOR OPEN AND SHORT
1. Check harness continuity between cooling fan motor-2 terminal 1 and IPDM E/R terminal 13, cooling fan
motor-2 terminal 2 and IPDM E/R terminals 10, 14.
Refer to Wiring Diagram.
2. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 9.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
9. CHECK COOLING FAN MOTORS
Refer to EC-585, "
Component Inspection" .
OK or NG
OK >> GO TO 10.
NG >> Replace cooling fan motors.
10. CHECK INTERMITTENT INCIDENT
Perform EC-450, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
OK or NG
OK >> Replace IPDM E/R. Refer to PG-17, "IPDM E/R (INTELLIGENT POWER DISTRIBUTION MOD-
ULE ENGINE ROOM)" .
NG >> Repair or replace harness or connector.
