Make:
HUMMER
Code:
B1000 46
Definition:
System Disabled Information Stored Invalid Serial Data Received
Description:
Ignition ON.  Ignition voltage is greater than 10 volts.
Cause:
DTC C0561 4BThis diagnostics detects if one or more of the module learning steps was not performed or failed during component replacement (New ECU or reprogrammed ECU).DTC C0561 54This diagnostics detects an over temperature condition with 1 of the 12 solenoids due to an extended ABS,  traction control and the vehicle stability enhancement system event lasting more than 45 seconds.DTC C0561 59This diagnostics detects if the ABS motor is continuously ON for greater than 60 seconds during the same ignition cycle due to;  Pedal pumping,  poor service bleed,  or a hydraulic leak.DTC C0561 71, 72, 74, and 75The EBCM receives an invalid serial data message or signal from another module which causes the EBCM to deactivate the antilock brake system,  traction control and the vehicle stability enhancement system.
Failure Type:
Calibration  or  Parameter Memory Failure
This sub type is used by the control module to indicate a calibration  or  parameter memory failure for embedded systems using FLASH memory. This is equivalent to EEPROM in RAM or ROM or EEPROM embedded systems.
