Exhaust System – V6 Page 6F – 3

The Catalytic converter can be damaged or
rendered ineffective, if:
• operated outside the limits of the closed
loop mixture control system
• the engine burns excessive amount of oil
• the exhaust temperature at the converter
is too high (exceeds 840°C).
The catalytic material is very sensitive to the effects of a rich or lean fuel mixture, which may cause the temperature of
the converter to rise rapidly. The catalytic converter normally operates at approximately 600 °C.
The catalytic converter is also sensitive to the use of leaded petrol. Using leaded fuel can cause deposits to form in the
converter, which restrict exhaust flow and prevent the catalyst from working. This will result in an increase in exhaust
backpressure and converter temperature.
NOTE
The use of unleaded petrol results in black
tailpipe deposits rather than the grey colour that
some people may normally associate with an
acceptable combustion condition. This black
colour resulting from the use of unleaded fuel
does not necessarily indicate a state of poor
engine tune. For V6 engines, Refer to: 6C1 – 1
Engine Management General Information.
Euro 3 Emissions Standards
The Euro 3 emissions standard is a European standard which aims at setting vehicle emissions targets to encourage
vehicle manufacturers to reduce harmful vehicle emissions such as Carbon Monoxide (CO), Hydrocarbons (HC) and the
various oxides of Nitrogen (NOx).

This vehicle is fitted with a supplemental
restraint system (SRS). Refer to section 9A
Restraints, in order to determine whether you
are performing service on or near the SRS
components or the SRS wiring.

Always use the correct fastener in the proper
location. When you replace a fastener, use
ONLY the exact part number for that
application. Isuzu will identify those fasteners
that require a replacement after removal and
fasteners that require thread lockers or thread
sealant. Unless otherwise specified, do not
use supplemental coatings (Paints, greases
or corrosion inhibitors) on thread fasteners or
fastener joints. Generally such coatings
adversely effect the fastener torque and the
joint clamping force, and may damage the
fastener. When you install fasteners, use the
correct tightening sequence and torque
specifications.

Automatic Transmission – 4L60E – General Information Page 7C1–8
2.4 System Protection Devices
Should 1st gear be selected and left in that range, the TCM will protect the engine from an over-speeding condition by
upshifting to 2nd gear at a pre-determined point. Similarly, the TCM provides high speed, downshift protection by
preventing a manual shift into 1st gear above pre-determined engine speeds.
Under severe operating conditions such as towing in high ambient temperatures, fluid temperatures can rise to a point
where lubrication breakdown can occur. In addition to having an oil cooler fitted to the vehicle, the 4L60E transmission is
also fitted with a transmission fluid temperature sensor located in the Transmission Range (TR) Pressure Switch
Assembly (PSA).
When fluid temperatures in excess of 135 °C are sensed, the torque converter clutch is applied as programmed, in 3rd or
4th gear. This action reduces further the fluid temperature during normal operation of the torque converter. While these
high fluid temperatures are sensed however, torque converter clutch apply is not available when the throttle opening is
above 50%.
Similarly, when the fluid temperature is below 29 °C, the TCM prevents torque converter clutch apply.
If a condition occurs, preventing electronic control of the transmission's functions, a 'Fail Safe' mode will default the
transmission to 3rd gear when either Drive or 3 is selected, applying also maximum line pressure. W hile in this mode, the
vehicle operator can still manually select 2, 1, Reverse, Park or Neutral, should the need arise.
2.5 Self Diagnosis
If any transmission operation controlled by the TCM begins to operate outside its pre-set parameters, the TCM has the
ability to store a range of diagnostic codes which can be accessed by the servicing technician, thereby localising the
problem.
2.6 TCM Sensors and Actuators
As indicated earlier, there are a number of sensors and switches providing input information for the TCM programming
that will allow the TCM to change the shift pattern, shift feel and torque converter clutch operation.
The TCM does this by comparing this input information with its predetermined values on shift pattern, fluid pressure
maps, shift duration parameters, extreme heat protection programming and adaptive controls.
In addition, each input signal and output actuator operation is also monitored and if outside its pre-set parameters, a
diagnostic code is logged for future reference by the servicing technician.

4.9 DTC P0218 – Transmission Fluid Overtemperature
DTC Description
This diagnostic procedure supports DTC P0218 Transmission Fluid Overtemperature.
Circuit Description
The flow of transmission fluid starts in the bottom pan and is drawn through the filter, control valve body assembly,
transmission case and into the oil pump assembly. The oil pump assembly pressurises the fluid and directs it to the
pressure regulator valve where it becomes the main supply of fluid to the various components and hydraulic circuits in
the transmission. Hot fluid exiting the torque converter flows through the converter clutch apply valve and into the
transmission cooler lines, to the oil cooler located in the vehicle radiator, and auxiliary cooler if equipped. From the cooler ,
fluid returns to cool and lubricate the front of the transmission. In forward drive ranges, D4 fluid from the manual valve is
routed through an orificed cup plug in the rear of the transmission case to feed the rear lube fluid circuit.
When the transmission control module (TCM) detects a high transmission fluid temperature (TFT) for a long period of
time, DTC P0218 sets. DTC P0218 is a type C DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
• No DTCs P0711, P0712 or P0713.
• The ignition switch is on for 5 seconds.
Conditions for Setting the DTC
The TFT is greater than 130°C for 600 seconds (10 minutes).
Action Taken When the DTC Sets
•
The TCM does not request the ECM to illuminate the MIL.
• The TCM freezes transmission adapt functions.

4.19 DTC P0742 – Torque Converter Clutch
System – Stuck On
DTC Description
This diagnostic procedure supports DTC P0742 Torque Converter Clutch (TCC) System – Stuck On.
Circuit Description
The torque converter clutch (TCC) solenoid valve is a normally-open exhaust valve that is used with the torque converter
clutch pulse width modulation (TCC PWM) solenoid valve to control fluid acting on the converter clutch apply valve. The
TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. W hen grounded by the
transmission control module (TCM), the TCC solenoid valve stops converter signal oil from exhausting. This causes
converter signal oil pressure to increase and move the converter clutch apply valve against spring force and into the
apply position. In this position, release fluid is open to an exhaust port and converter feed fluid fills the apply fluid circu it.
The converter feed fluid applies the TCC. When the TCM no longer provides a ground path, the TCC solenoid valve de-
energizes and apply fluid exhausts, releasing the TCC.
W hen the TCM detects low torque converter slip when the TCC is commanded off, then DTC P0742 sets. DTC P0742 is
a type B DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
• No DTCs P0722, P0723, P0741 P02763, P02764, P02769 or P02770.
• Ignition voltage is 8 – 18 V.
• The engine run time is greater than 5 seconds.
• The IMS range is D4.
• The transmission fluid temperature is 10 – 130°C.
• The engine speed is 500 – 6,500 r.p.m. for 5 seconds, then 800 – 4,400 r.p.m.
• The engine torque is 156 – 881 Nm.
• The throttle position is greater than 10 percent.
• The transmission is not in 1st gear and the gear ratio is 0.95:1 – 1.56:1.
