DTC P0603 ECM POWER SUPPLY
2007 Pathfinder
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 Procedure
UBS00KBS
1.
CHECK ECM POWER SUPPLY
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check voltage between ECM terminal 121 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 3.
NG
>> GO TO 2.
2.
DETECT MALFUNCTIONING PART
Check the following.
●
20A fuse
●
IPDM E/R harness connector E121
●
Harness for open or short between ECM and battery
>> Repair open circuit in harness or connectors.
3.
CHECK INTERMITTENT INCIDENT
Refer to
EC-145, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"
.
OK or NG
OK
>> GO TO 4.
NG
>> Repair or replace harness or connectors.

DTC P0605 ECM
2007 Pathfinder
DTC P0605 ECM
PFP:23710
Component Description
UBS00KBC
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.
On Board Diagnosis Logic
UBS00KBD
This self-diagnosis has one or two trip detection logic.
FAIL-SAFE MODE
ECM enters fail-safe mode when the malfunction A is detected.
DTC Confirmation Procedure
UBS00KBE
Perform PROCEDURE FOR MALFUNCTION A first. If the 1st trip DTC cannot be confirmed, perform
PROCEDURE FOR MALFUNCTION B. If there is no malfunction on PROCEDURE FOR MALFUNCTION
B, perform PROCEDURE FOR MALFUNCTION C.
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.
PROCEDURE FOR MALFUNCTION A
With CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
If 1st trip DTC is detected, go to
EC-473, "Diagnostic Procedure"
.
With GST
Follow the procedure “With CONSULT-II” above.
