ECU AND MOTOR DIAGNOSTIC

Incidents:

Machine on its stand:
- Motor not running
- The motor runs if helped by turning the rear wheel by hand
- The motor revs hard (E.g.: 67 km/h maximum speed on the TEP96)
- The motor power cables are hot

Causes:

ECU destroyed
Motor destroyed (in this case, the ECU is also faulty)

Troubleshooting:

Important:

Do not fit another ECU to find the fault, it may also be destroyed if the motor is faulty
The machine charge must be over 50%

1/Fault diagnosis:

Leave the machine on its stand
Turn on the ignition, enter the code on the keypad
Connect the TEP96 and select READ VARIABLES

Set the throttle to 100% and take the measurements for each driving mode
