Re: Dakota Dig. BIM-01-2 info for Gen IV
To edit my post above: I was browsing some alldata stuff, and realized the ecm does know what gear is selected.
Quote:
PRNDL Display
The IPC displays the selected gear position as determined by the ECM. The IPC receives a serial data message from the ECM indicating the gear position. The PRNDL display blanks if:
The ECM detects a malfunction in the transmission range switch circuit.
The IPC detects a loss of serial data communications with the ECM.
|
Evidently, the prndl position is bounced through a lot of modules before being displayed.
Transmission Control Module --> Engine Control Module --> Body Control Module. Here, it switches to low speed data, and goes to the Instrument Panel Cluster.
