4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P0650 (Flash DTC 77)
Check Engine Lamp Circuit Open/Short
060RW136
Circuit Description
The check engine lamp circuit receives through Meter
10A fuse the battery, current flowing in the order of Meter
and check engine lamp.
Action Taken When the DTC Sets
The ECM will illuminate the malfunction indicator lamp
(MIL) the first time the fault is detected.
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0650 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.
Diagnostic Aids
Check for the following conditions:
Poor connection at ECM – Inspect harness connectors
for backed-out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal-to-wire connection.
Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
lamp test display on the Tech 2 while moving
connectors and wiring harnesses related to the check
engine lamp. A change in the display will indicate the
location of the fault.
If the Tech 2 indicate DTCs P0650 and P0381, check the
meter circuit necessarily.
