ELECTRIC SYSTEM
Pegaso 650 I.E.
6.5.2 TROUBLESHOOTING ◆ Position the vehicle on the stand. ◆ Turn the ignition switch to position “2”.
The diagnostic warning light "û" (1) comes on.
aCAUTION Do not carry out any operation on the components of the vehicle with the ignition switch in position “2”. With the engine stop switch in position "1", it comes on whenever the ignition switch is brought to position "2" and remains on, with low light intensity, thus testing the correct operation of the injection circuit. ◆ Start the engine.
If the diagnostic warning light "û" (1) goes out a few seconds after the engine start, this means that the central unit has not detected any anomaly. If the diagnostic warning light “û” remains on after the engine start or comes on during the normal operation of the engine, this means that the electronic unit has detected an anomaly.
6.5.3 FAILURE CODE VERIFICATION ◆ Remove the saddle, see p 7.1.7 (REMOVING THE
SADDLE).
aCAUTION Do not start the engine. ◆ Put the gearshift into neutral. ◆ Turn the ignition switch to position “2”. ◆ Turn the engine stop switch to position “2”. ◆ Short-circuit the two contacts of the central unit electric
connector (2) (see figure) for twelve seconds, in order to activate the "workshop mode".
NOTE The "workshop mode" interrupts the operation of the injection system, the coil and the fuel pump for safety reasons. At this point: – the diagnostic warning light (1) positioned on the dashboard will blink for five seconds, confirming in this way that the "workshop mode" has been successfully activated.
NOTE Each failure code consists of 2 digits. The failure codes correspond to the blinking of the warning light, according to the following codification: EXAMPLE: failure code 53 = 5 long blinks + 3 short blinks.
NOTE Between two different failure codes the warning light remains off for 3 seconds. ◆ Refer to the following table to verify the correspond-
ence between the failure code and the problem that is being dealt with.
NOTE Short-circuit the two contacts of the central unit electric connector (2) (see figure) for twelve seconds, in order to exit from the "workshop mode". The diagnostic warning light (1) positioned on the dashboard will blink for five seconds, confirming in this way that the "workshop mode" has been successfully abandoned.
