2/To Determine The Faulty Component - PEUGEOT E1A Workshop Manual

ECU AND MOTOR DIAGNOSTIC

2/To determine the faulty component:

Remove the saddle and the saddle cover
Turn on the ignition, enter the code on the keypad
Stay in handling mode and fully open the throttle
Measure the voltages with a multimeter set to the DC voltmeter range
Between the +MOT and the –MOT correct value 5V ±1V
Between the +MOT and EXC correct value 8V ±1V
If the values are lower, the ECU is faulty.
If the values are higher, the motor is faulty (in this case the ECU is also faulty).
