1. This has been separated from the next row SPN 615 as this is the only case when the DTC with SPN
615 can signal the Lamp status set to Amber.
2. SPN 615 with the Lamp status set to Red indicates that other critical EHPS error has happened. The
user must retrieve an error code from the EHPS error buffer and use the table in section 2 to locate
the source of a problem.
The PVED-CL supports DM1, DM2 and DM3 according to SAE J1939-73 diagnostic protocol (see
PVED-CL
Communication Protocol Technical Information
, 11079551).
A sub-set of all possible PVED-CL fault codes are represented as standardized J1939-73 Suspect
Parameter Numbers (SPN). The sub-set is limited to interface-related faults, which are typically causing
most troubles.
AD1 and/or AD2 Short-circuit
Each of the two analog input ports are monitored for short-circuits to GND, VCC or positive battery
supply. The Failure Mode Identifier (FMI) differentiates between the two type of short-circuits. An internal
pull-down resistor on both analog input ports will pull the input level to GND if an analog input port is
left open. No analog input diagnostic is active if the analog input is not mapped.
Missing CAN Sensor Set-points
SPN 611 indicates a fault due to invalid timing or missing input signals from the sensors, most likely due
to a failing CAN sensor or cable tree fault. In this context, input signals are both CAN messages and
analog samples from sensors. However, missing analog samples or invalid timing of analog samples can
only be caused by an internal PVED-CL fault – nothing can be concluded about the analog sensors from
this SPN.
Invalid timing means that the requirements to the period that data has to be received within, has not
been met. This could again be caused by an incorrectly configured CAN sensor or a heavy CAN bus-load,
restricting the CAN sensor messages to be transmitted at their expected time.
