GENERAL

Here is the basic order suggested to diagnose a suspected engine management related problem:

– Check the chart in TROUBLESHOOTING section to have an overview of problems and suggested so-

lutions.

– Check if the engine management system (EMS) pilot lamp lights up. If so, use the VCK (Vehicle Com-

munication Kit) and look for fault codes to diagnose the trouble.

– Check all fuses, relay(s) and battery (if so equipped).
– Check spark plugs condition.
– Check all connections of the wiring harness.

Refer to COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT section for procedures.

TROUBLESHOOTING

The following chart is provided to help in diagnosing the probable source of simple troubles.

Monitoring Beeper and Light Coded Signals

WARNING SIGNALS

LED

BEEPER CODE

WARNING

DESS/RER

HI-TEMP

POSSIBLE CAUSE

REMEDY

2 short beeps

(when engine is started).

Blink

Confirms that proper tether cord
cap is installed.

NOTE: Engine can rev above clutch
engagement.

Normal condition. No problem
detected.

2 short beeps every second.

Closed throttle reset was not
performed

Perform closed throttle reset.

1 short beep followed by 1 long
beep

(when engine is running).

Engine overheat at idle

NOTE: Engine stops automatically
after 4 minutes of idling (without
depressing the throttle lever) and
engine temperature is higher than
85°C (185°F).

Refer to TROUBLESHOOTING.

NOTE: Depressing throttle lever
within 4 minutes will reset timer.

EMS fault (1).

Use B.U.D.S. and check fault
codes

(1) See EMS Fault code table for more details.

EMS FAULT CODES

General

The faults registered in the ECM (engine control module) are kept when the battery is disconnected.

IMPORTANT: After a problem has been solved, ensure to clear the fault(s) in the ECM using the VCK.
This will properly reset their states.

Many fault codes at the same time is likely to be burnt fuse(s).

For more information pertaining to the code faults status and report, refer to B.U.D.S. online help or to
the EMS fault code table.

Supplemental Information

When using the service action suggested in the Fault section of B.U.D.S., the system circuits are referred
to as DA-41, which means connector on the ECM and the circuit 41.

Fault code P0654

If this code occurs and tachometer works normally, disregard this fault code.

Fault code P0336

This code occurs when engine RPM goes too high which could happen under some mechanical-related
circumstances and is not necessarily related to a problem with the engine management system.

Section 05 ENGINE MANAGEMENT (POWER TEK)

Subsection 02 (DIAGNOSTIC PROCEDURES)

Fault code P1102 (TPS “Out of Range” Fault)

It is caused by the sensor reading going out of its allowable range. This fault can occur during the whole
range of movement of the throttle.

To diagnose this fully, it is recommended to operate the throttle through its full range. It is also recom-
mended to release the throttle quickly as this may also reveal a fault that is intermittent.

POSSIBLE CAUSES

ACTION

Check if connector is disconnected from TPS

Reconnect.

Check if sensor is loose

Tighten sensor and reset Closed Throttle.

Inspect sensor for damage or corrosion

Replace sensor and reset Closed Throttle.

Inspect wiring (voltage test)

Repair.

Inspect wiring and sensor (resistance test)

If bad wiring, repair.

If bad TPS, replace and reset Closed Throttle.

Test sensor operation (wear test)

Replace sensor and reset Closed Throttle.

Fault code P1104 (TPS “Adaptation Failure” Fault)

It is caused by the idle position moving out of an acceptable range.

Following problems can be caused by a TPS “Adaption Failure“:

– Idle speed is out of range.
– Engine stops, when throttle is released quickly.
– Engine runs inconsistent in low partload or low RPM.

POSSIBLE CAUSES

ACTION

Sensor has been replaced and TPS closed

position not reset

Reset Closed Throttle.

Carburetor has been replaced and TPS closed

position not reset

Reset Closed Throttle.

EMS has been replaced and TPS closed

position not reset

Reset Closed Throttle.

Throttle cable too tight

Adjust cable and reset Closed Throttle.

Sensor is loose

Tighten sensor and reset Closed Throttle.

Throttle bracket is loose

Fix and reset Closed Throttle.
