Visual IndicatorsAs explained in earlier sections of this document, if either the raised mode (rear only) or lowered mode(partial) is selected, the respective pushbutton LED will flash. Additionally, if the raised mode (entirevehicle), lowered mode (lowest possible mechanical position), or the tag dump mode is selected therespective LED will be “ON” continuously. The user interface also contains a suspension and an airpressure indicator. Should the system ECU detect a problem, the suspension light will blink in such amanner as to identify an error code associated with the fault. Additionally, should the system air pressurefall below 90psi, the system ECU will illuminate the air suspension indicator.Note: The following section provides more information regarding the specific system error codes.Error CodesThe ECU has the ability to monitor the SAMS system and detect electrical problems. Should the ECUdetect a problem, a visual indication will be given by flashing the suspension indicator located on the userinterface panel in such a manner as to represent a two or three-digit code. The first number of the codecan be identified by counting the first series of flashes. It will be followed by a short pause, and thenprovide a second series of flashes to represent the second number of a two-digit code (if applicable, thesecond number will be followed by another short pause, and then provide a third series of flashes torepresent a three-digit code). For example one flash, followed by a short pause, and then three additionalflashes would illustrate a code 13.In the event of more than one detected problem, the ECU will cycle through this process and flash anindividual error code for each identified problem. The ECU will continue to flash the error code(s) untilthe problem(s) have been corrected. Once the problem(s) are corrected, the ECU will proceed to turn offthe suspension indicator. A list of potential error codes and their probable cause are as follows:• 11 (eleven) – Rear Drive, Driver Height Sensor• 12 (twelve) – Rear Drive, Curb Height Sensor• 13 (thirteen) – Rear Drive, Driver Pressure Transducer• 14 (fourteen) – ECU Sensor Reference Voltage• 21 (twenty-one) – Rear Drive, Curb Pressure Transducer• 22 (twenty-two) – Rear Tag, Driver Pressure Transducer• 23 (twenty-three) – Rear Tag, Curb Pressure Transducer• 24 (twenty-four) – X Axis Inclination Sensor• 31 (thirty-one) – Y Axis Inclination Sensor• 32 (thirty-two) – Front, Driver Height Sensor• 33 (thirty-three) – Front, Curb Height Sensor• 34 (thirty-four) – Supply Pressure Transducer• 41 (forty-one) – Invalid Battery Voltage• 42 (forty-two) – Not Used• 43 (forty-three) – Low Battery Voltage (less than 9.7VDC)• 44 (forty-four) – High Battery Voltage (greater than 14.8VDC) |
