DIAGNOSIS
GENERAL ON-VEHICLE INSPECTION
The operating condition of the charging system is
indicated by the charge warning lamp. The warning
lamp comes on when the starter swtich is turned to
“ON” position. The charging system operates normallyif the lamp goes off when the engine starts. If the
warning lamp shows abnormality or if undercharged or
overcharged battery condition is suspected, perform
diagnosis by checking the charging system as follows:

1. Check visually the belt and wiring connector.
2. With the engine in stop status, turn the starter
switch to “ON” position and observe the warning
lamp.
1) If lamp does not come on:
Disconnect wiring connector from generator,
and ground terminal “L” on connector side.
2) If lamp comes on:
Repair or replace the generator.

6E–93 4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS
Circuit Description
The rail pressure control valve (RPCV) is built in the high
pressure oil circuit.
RPCV is an important device which is used to control oil
pressure in the HEUI system.
The circuit receives current through Engine 15A fuse from
the battery, current flowing in the order of RPCV.
Action Taken When the DTC Sets
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 P1196 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
Rail Pressure Control display on the Tech 2 while
moving connectors and wiring harnesses related to the
Rail Pressure Control. A change in the Rail Pressure
Control display will indicate the location of the fault.
If DTC P1196 cannot be duplicated, the information
included in the Failure Records data can be useful in
determining vehicle mileage since the DTC was last set.
If it is determined that the DTC occurs intermittently.

6E–109 4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P1217 (Flash DTC 36)
High Oil Temp Warning
060RW129
Circuit Description
The engine oil temperature (OT) sensor is a thermistor
mounted on a oil manifold. The Engine Control Module
ECM applies a voltage (about 5 volts) through a pull-up
resistor to the OT signal circuit. When the engine oil is
cold, the sensor (thermistor) resistance is high, therefore
the ECM will measure a high signal voltage. As the
engine oil warms, the sensor resistance becomes lower,
and the OT signal voltage measured at the ECM drops.
Action Taken When the DTC Sets
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 P1217 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.
High Oil Temperature Warning may sometimes be
given due to High Coolant Temp Warning. On this
occasion, recognize DTC P0217 and give priority to
High Coolant Temp Warning.

Engine Over Speed Warning
060RW133
Circuit Description
The CKP reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolution,
CKP crankshaft reference pulses will be produced. The
Engine Control Module ECM uses the CKP reference
signal to calculate engine RPM and crankshaft position.
Action Taken When the DTC Sets
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 P0219 can be cleared by using the Tech 2 “Clear
