EFI Fuel System

11. Reconnect the battery cable and all external loads.

Remove the rubber band from the throttle lever.

Readjust the idle speed to the equipment

manufacturer’s specified setting and recheck the

high-speed, no-load RPM setting. Observe the

overall performance.

TPS Initialization Procedure

For “32 Pin” (MSE 1.1) Plastic-Cased ECU Only

(“Auto-Learn” Initialization)

1. Check that the basic engine, all sensors, fuel, fuel

pressure, and battery are good and functionally

within specifications.

Important!

2. Remove/disconnect all external loads from the

engine (belts, pumps, electric PTO clutch,

alternator, rectifier-regulator, etc.).

3. Locate the service connector plug in the wiring

harness. To initiate the TPS auto-learn function,

connect a jumper wire from the TPS initialization

pin #24 (violet wire) to the battery voltage pin

(red wire), or use the jumper plug with the blue

jumper wire. If using the PC-based diagnostic

software (see Section 2), go to “Special Tests” and

follow the prompts to complete.

4. Start the engine and immediately observe the

Malfunction Indicator Light (MIL). The light

should start blinking 4 consecutive times every 2

seconds.

5. Remove the jumper wire or plug from the service

connector plug.

6. Run the engine at full throttle (above 3000 RPM),

to warm up the engine and initiate O

sensor

function in “closed-loop” operation.

7. Watch the “MIL”. When the light starts blinking

rapidly, (5 blinks per second), move the throttle

lever to the low idle speed position. Check and

adjust the idle speed to 1500 RPM, using a

tachometer. The lamp should continue to blink

rapidly for another 30 seconds before switching

to a slow blink.

8. When the “MIL” blinks slowly, do not do

anything but wait until the “MIL” shuts off. This

indicates that this procedure has been completed

successfully.

9. Shut off the engine. If the learn procedure was

successfully completed, the external loads

removed/disconnected in Step 2 may be

reconnected.

If the procedure was unsuccessful see Steps a.

and b. following.

a. If the “MIL” goes back to blinking 4

consecutive blinks every 2 seconds during the

procedure, the engine and O

sensor have

cooled down and gone out of “closed-loop”

operation, prohibiting the learning from

occurring. Repeat Steps 6-9.

b. If the “MIL” stays “on” continuously for more

than 15 seconds during the procedure, there is

probably a fault code present, turn off the

ignition. Then initiate the fault code sequence,

by turning the key switch on-off-on-off-on,

leaving the key “on” in the last sequence (each

key on/off sequence must be less than 2.5

seconds long). The fault detected must be

corrected before the “auto-learn” function can

be re-initiated. The PC-based diagnostic

software may be used to read out the fault

code and assist with troubleshooting and

repair.
