OPERATION - 5 VOLT SUPPLIES Primary 5–volt supply: ² supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor. ² supplies the required 5 volt power source to the Camshaft Position (CMP) sensor. ² supplies a reference voltage for the Manifold Absolute Pressure (MAP)...

As far as I can remember the tacho signal comes from the crank into the PCM (don't know the way it gets measured yet, will do some research) from there it communicates a tacho signal to the "Body Control Module" (BMC) via PCI comms which translates the signal and sends it to the cluster via CAN...

Thanks that's great info. It makes a lot more sense now. One question with regards to the crank sensor and the amount of pulses it sends per revolution. Would it not be easier to weld a standard Jeep pullyto the Lexus crank and pick-up the signal from there? IOW on top of the Lexus pully...

I will be installing a 1uz-fe. It's nice and cheap if something goes wrong and relatively straight forward. Not to sure abou tthe trigger wheel?:o But as far as I can understand the basic working of a crank positioning sensor is basically just a magnet that spins with the actual crank and a...

Thanks let me know how it goes

Your right I was mistaken on how the fly by wire setup works...:D The Jeep runs a cable from the pedal to the throttle body there you will find a TPS and Servos to control cruise control etc. That should make it easy to get the motor running:rolleyes:

The PCM continually monitors the crankshaft position sensor to determine the engine speed, then sends the proper engine speed messages to the instrument cluster. This might get tricky as I would need to split the signal to the aftermarket ECU and give the standard Jeep system a signal. It...

Speedo Vehicle speed is monitored by the two front and one rear wheels via speed sensors. This 12V signwave is sent to the CAB (Antilock brakes system) with in turn sends it to the PCM via PCI Bus. From there it gets sent to the BCM via PCI and then onto the Dashboard via PCI. Thia is done...

Temp sensor The temp sensor is monitored by 5v output citcuit from the Powertrain control module to the sensor and back to the PCM. This will be easy to get right...

The turn signal indicators, security indicator, washer fluid indicator, and coolant low indicator (diesel engine only) use hard wired inputs to the Dasboard.

1 - skis indicator 17 - rear fog lamp indicator 2 - airbag indicator 18 - abs indicator 3 - low fuel indicator 19 - charging indicator 4 - wait-to-start indicator 20 - water-in-fuel indicator 5 - overdrive-off indicator 21 - engine temperature gauge 6 - coolant low indicator 22 -...

This is what I need to get working on the dash to complete the convertion: Coolant Temperature Gauge Fuel Gauge Speedometer Tachometer Charging Indicator Coolant Low Indicator (with Diesel Engine only) Cruise Indicator (with Speed Control only) Four-Wheel Drive Full Time Indicator (with...

I've read up a little on the CRD Jeep PCM (ECU) and it seems all it really reads from the engine is Temperature, Oils pressure, CAM position. Does that sound right? I know a diesel is less sophisticated but that seems way less than I expected...

Thanks will follow up with Fana van Zyl for the sump. Your right to get the engine running is nothing but it will take some time and effort to get all the other goodies to work right...:)

The Jeep uses a PCI Bus to communicate with other components like the cluster etc. I will be using an aftermarket ECU to run the Lexus but use some of the output of this ECU to send hardwire voltage signals to the standard Jeep "Powertrain Control Module" and "Body Control Module" this will then...
