P1751

Note for DTC 18159 / P1751:
^ Conditions for fault recognition: Battery voltage higher than 16 Volt.

^ Battery monitoring differentiates between four areas: (U= battery voltage) First U < 7 Volt => Transmission goes into mechanical backup with non-active control module; Second 7 Volt < U < 9 Volt --> Transmission range is held for about 2.5 sec., if U is then still in this range, the transmission goes into mechanical backup with non-active control module; Third 9 Volt < U < 16 Volt -> voltage is OK; Fourth U > 16 Volt => transmission goes into mechanical backup with non-active control module.
