Install the IPC. Ensure everything is connected properly. The replacement IPC requires SPS Programming and IPC Setup procedures to be performed. It does not matter which procedure is performed first. 2. Start the engine and then select IPC Setup. You must have the engine running before performing the IPC Setup. 3. Select IPC Setup. With the engine running, enter the appropriate mileage and engine hours. 4. Select “OK”. Review the pop up asking you to verify the mileage and engine hours. Move the pop up out of the way if necessary to view the verification screen. This may require a click and drag of the dialog box. 5. Verify that the mileage and engine hours are correct and select “OK”. DO NOT turn the ignition OFF until the engine has “run” for approximately seven (7) minutes. Allowing the engine to idle for this period of time allows the IPC to accumulate 1/10th of an hour and write the correct engine hour value to the permanent memory. The engine must be running before set up is performed and run for approximately seven minutes after the user selects “OK” confirming their mileage/engine hour inputs. After approximately seven minutes, shut the engine OFF and complete the event. The seven minute clock starts after you select “OK”, confirming the entries. Note: Based on feedback from technicians, we are currently making changes to the “IPC Setup” application which will include several enhancements to the set up screens. These are scheduled to be released and available in TIS2WEB very soon. Important: Only IPC conditions listed in the Condition section of the bulletin are covered under this special coverage program. In a small number of vehicles, the condition may be intermittent and the gauge sweep test may not always verify the condition. IPC Performance IPC performance may be affected by the following conditions: Customer Comments and Observations Customers who describe gauge performance as jumpy, sticky, slow or erratic. Gauge performance may also be described as being inoperative or inaccurate. For example, for a period of time the speedometer may appear to move normally but be inaccurate and not return to zero (0) after the vehicle comes to a stop. This inaccurate condition may be more or less pronounced during the drive cycle and may, for a time, return to normal operation. A Tech 2 sweep test may not reveal the condition. 1. Perform a gauge sweep test to determine/verify that an IPC gauge is sticking, stuck, or inoperative. Using the Tech 2, navigate to the following screens to perform the gauge sweep test: Body -> Instrument Panel Cluster -> Special Functions -> IPC Gauges -> Display(s) Test. • Cold temperatures • Temperature fluctuations • High humidity • Driving over rough surfaces such as dirt roads or potholes

The ATF level gauge (dip-stick) has been discontinued, and the ATF inspection method and the oil level inspection method have been changed. This mechanism consists of a refill plug, overflow plug, ATF temperature sensor No.2, and A/T OIL TEMP temperature warning light. ATF Filling procedures using SST (09843-18020): When a large amount of ATF needs to be filled (i.e. after removal and installation of oil pan or torque converter), perform the procedure from step 1. When the small amount of ATF is required (i.e. removal and installation of the oil cooler tube, repair of oil leak), perform the procedure from step 7. 1) Raise the vehicle keeping it level. 2) Remove the refill plug and overflow plug. 3) Fill ATF from the refill plug until it overflows from the overflow plug. 4) Install the overflow plug. 5) Fill the specified amount of ATF determined by procedure and install the refill plug. Example 6) Lower the vehicle down. 7) Use the SST (09843-18020) to short the terminals Tc and CG of the DLC3 connector: 8) Start the engine and allow it to idle. A/C switch must be turned OFF. 9) Move the shift lever slowly through each of the positions from the P to the L position, and move it back to the P position. 10) Move the shift lever from the D position, and quickly move then back and forth between N and D (once per less than 1.5 seconds) for at least 6 seconds. This will activate the oil temperature detection mode. Standard: The A/T OIL TEMP warning light remains illuminated for 2 seconds and it goes off. 11) Return the shift lever to the P position and disconnect the terminal Tc. 12) Idle the engine to raise the oil temperature. 13) Immediately after the ATF OIL TEMP warning light turns on, lift the vehicle up. The A/T OIL TEMP warning light will indicate the ATF temperature according to the following table. (Insert table here) 14) Remove the overflow plug and adjust oil quantity. If the ATF overflows, go to step 17, and if the ATF does not overflow, go to step 15. 15) Remove the refill plug. 16) Fill ATF to the refill plug until it flows out from the overflow plug. 17) When the ATF flow slows to a trickle, install the overflow plug. 18) Install the refill plug (only if the refill plug has been removed). 19) Lower the vehicle down. 20) Turn the ignition switch OFF to stop the engine.

Toyota Landcruiser / Scout Weatherproof Harness Wire Harness Installation Instructions

Grounding the Automobile A perfectly and beautifully wired automobile will nevertheless have bugs and problems if everything is not properly grounded. Do not go to the careful effort of installing a quality wire harness only to neglect proper grounding. Note: The Painless Wire Harness Kit includes no ground wire except the black wire from the two headlamp connectors. You must supply ground wire (14-16 gauge) for all circuits. 6.3.1 Connect a Ground Strap or Cable (2-gauge minimum) from the Negative Battery terminal to the automobile chassis (frame). 6.3.2 Connect a Ground Strap from the Engine to the chassis (even a 10-gauge wire is too small) . DO NOT RELY UPON THE MOTOR MOUNTS TO MAKE THIS CONNECTION . 6.3.3 Connect a Ground Strap from the Engine to the Body. 6.3.4 If you have a fiberglass body you should install a terminal block to ground all your Gauges and Accessories. Ground the Terminal Block with at least a 12-gauge wire to the chassis. 6.4 Terminal Installation and Making Connections Note: In the following steps you will be making the circuit connections. Before you start, you should carefully read Sections 7.0 through 10.0 , as appropriate, and continually refer to Section 10.0 , DOUBLE- CHECKING your routing and length calculations before cutting any wires and making connections. Give special attention to Turn Signal and Ignition Switch connections. These can be somewhat confusing. 6.4.1 Have all needed tools and connectors handy. 6.4.2 Select the correct size terminal for the wire and stud application. 6.4.3 Determine the correct wire length and cut the wire. Remember to allow enough slack in the harness and wires at places where movement could possibly occur, such as automobile body to frame, frame to engine, etc. Double-check your calculations. 6.4.4 Strip insulation away from wire. Strip only enough necessary for the type of terminal lug you are using. Note: In the following step, make sure that the terminal is crimped with the proper die in the crimping tool. An improper crimp will NOT make a good connection. 6.4.5 Crimp the terminal onto the wire. CAUTION: DO NOT OVER-CRIMP! 6.4.6 Connecting the harness throughout the groups is a redundant process. Make sure that each wire is FIRST properly routed and THEN attach. DO NOT ATTACH FIRST THEN ROUTE AFTERWARD. 6.4.7 When all wires are attached, tighten the mounts and ties to secure harness permanently. 6.5 Testing The System 6.5.1 Use a small (10 amp or less) battery charger to power up the vehicle for circuit testing. If there is a problem anywhere, the battery charger’s low amperage and internal circuit breaker will provide circuit protection. CAUTION: IF YOU HAVE NOT YET DISCONNECTED THE BATTERY FROM THE AUTOMOBILE, DO SO NOW! DO NOT CONNECT THE BATTERY CHARGER WITH THE BATTERY CONNECTED. Connect the battery charger’s NEGATIVE output to the automobile chassis or engine block and its POSITIVE output to the automobile’s positive battery terminal. 6.5.2 INDIVIDUALLY turn on each light, ignition, wiper circuit, etc. and check for proper operation. Note: The turn signals will not flash properly if you do not have both the front and rear bulbs installed and connected. 6.5.3 When all circuits check out THEN attach the battery cable to the battery for vehicle operation


INSTALLATION: Rotate the main trunnion of the rocker arm so that the flat machined surface is facing up, then lower the rocker arm onto the rocker stud so that the roller tip is contacting the valve and the pushrod is seated into the cup. Rotate the engine by hand until cylinder #1 is at TDC on the compression stroke (the rotor on the distributor should be lined up with cylinder #1′s spark tower). If you are using hydraulic lifters, rotate the pushrod between your fingers as you tighten the rocker arm adjustment nut, once you start to feel drag in the pushrod you are at zero lash. Continue tightening the adjustment to set the lifter preload according to your camshaft installation instructions, then use an allen wrench to tighten the posi-lock. If you are using mechanical lifters, use a feeler gauge while tightening the adjustment nut to set your valve lash to the clearance listed in the camshaft installation instructions, then use an allen tool to tighten down the posi-lock. Complete this procedure for both the intake and exhaust rockers, then rotate the crankshaft 90° and repeat this procedure on the next cylinder in the firing order. Continue doing so until all 16 rocker arms have been properly installed and adjusted. Proper operation can be verified by rotating the crank by hand and observing the motion of the pushrod and the position of the roller on the valve tip. The pushrods must never contact the cylinder head walls and the roller tip must maintain at least 50% contact with the valve tip during a full rotation of the camshaft. If the pushrod contacts the cylinder head or the roller fails to maintain sufficient contact with the valve tip you will need to loosen your rocker stud and adjust your pushrod guideplate until proper valvetrain alignment is achieved.
