Hi guys,

i am new to this forum.
I am looking for ECU flash file for Wizard 3.2L Auto 4WD, can anyone help me?

i am getting these errors when scanning :

P0342
P0713
P0748
P1860

Mechanics say that it is maybe the ECU defective.
Please help with troubleshooting / diagnostics for finding other errors like in wiring.

Any help would be appreciated.

DTC P0342 is a Camshaft Position Sensor (CPS) code. The CPS is used during startup to determine which cylinder should be the first to fire. An inoperative CPS does not prevent the engine from starting, it just takes more crankshaft revolutions to start and run.

DTC P1860, P0748 and P713 are 4L30e transmission failure codes.

DTC P1860 is a Torque Converter Clutch (TCC) solenoid electrical problem.
DTC P0748 is a Pressure Control solenoid electrical problem.
DTC P0713 is a ATF temperature sensor electrical problem.
The TCC solenoid control signal, Pressure Control solenoid signal and the ATF temp sensor signal are all connected to the ECU using the same 5 pin transmission electrical connector, it would be a good idea to make sure the connector is plugged in.

I am 99.99% sure no one in the forum has a 1998 Wizard/Rodeo/Passport ECU "flash file".

What problem are you trying to fix?

When the car was bought the Reverse gear was not working , had to give full gass to let it reverse.
So the guys took out the gearbox and renew a lot of things, now it is working good but
the check engine stays on and check trans is flashing , when scanning i am getting these codes mentioned earlier.
When driving i think the 3th or 4th is not activating..

they say they tested solenoids and all is good.

i am trying to solve all the mentioned codes, so i can drive the car as normal.

Did you check to see if the transmission 5 Pin electrical connector is plugged in as I suggested ?
Do you have an ohm meter and know how to operate it?

Disconnect the ECU C-3 Blue connector and measure the resistance between pins E3 and E4 of the harness connector. The expected resistance is about 4 ohms (PCS coil resistance). If the circuit reads open, check the continuity between the ECU C-3 Blue connector pins E3 and E4 and the 5 Pin connector Pins 1 and 2.

The measured resistance is too high.
I think E3 and E4 are the pins I marked in yellow.
If you disconnect the 5 pin connector and you still have the same resistance reading that will confirm your currently measuring the wrong pins.
Btw if the latch on the 5 pin connector plug is broken the plug can be mated to the transmission connector incorrectly.

The 5 Pin transmission connector is on the LH side of the overdrive section which is located on the front of the transmission assembly. The overdrive section has the smaller ATF pan held in place with 12 bolts.
The 5 Pin is used with 90-99 transmissions, 00-03 have a 4 pin at this location.

Check the operation of the Vacuum Solenoid Valve (VSV) and the vacuum hoses from the VSV to the Axle Acuator and from the vacuum tank to the VSV.
