13) TEMPERATURE
This message signals that controller temperature has exceeded 76°C.
Maximum current is reduced step by step to zero at a temperature of 86°C. Possible
causes:
a) If the alarm is output immediately after system ON with cold controller,
temperature monitoring is faulty (replace controller!)
b) If the alarm is output after relatively short period of operation,heat is
insufficiently dissipated (check installation and fixing screws)
14) NO FULL COND.
Test during full ride;
If during full ride, the voltage at connection VMN is > 1/3 VBatt, the diagnosis circuitry is
faulty and the system switches off.
If error persists, replace controller (logic unit).
