Control module power supply
|
Battery voltage (+30 circuit)
Current (+30 circuit) is supplied via fuse 12 to pin 33 (A) on the control module. The control module uses this current (+30 circuit) for the bus function when the ignition key is in the OFF position (+15).
Battery voltage (+15 circuit)
Current (+15 circuit) is supplied via fuse B to pins 31 (A) and 22 (A) on the control module. The leads are connected internally. The control module is activated by +15 current.
Diagnostics
Should the power supply drop below 9 V or exceed 16 V for at least 0.5 seconds, diagnostic trouble code P0560 will be generated and the TCM will go into Limp-Home mode.
