Normal Operation And Fault Conditions
The SASM is self-monitoring and capable of setting Diagnostic Trouble Codes (DTCs) to alert of potentialinternal errors. When one or more of these Diagnostic Trouble Codes (DTCs) appear, they can be resolvedby resetting the SASM using a diagnostic scan tool routine called SASM Reset.
PPT I ABS MODULE DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| B1016:19 | Status Switch: Circuit Current Above Threshold | This DTC sets if the SASM logic power circuit current is greaterthan 1.5A and less than 2.0A for at least 1 second or the current isgreater than 2.0A for less than 1 second. |
| C1B00:1C | Steering Angle Sensor: Circuit Voltage Out Of Range | This DTC sets if the voltage supplied to the internal SASM sensorsis less than 0.48 volt or greater than 6.5 volts. |
| C1B00:49 | Steering Angle Sensor: Internal Electronic Failure | This DTC sets due to a failure of the internal SASM sensors. |
| C1B00:62 | Steering Angle Sensor: Signal Compare Failure | The SASM monitors the input and output of the internal sensorsand compares the sensors to one another. This DTC sets if theinternal SASM sensors do not agree with each other. |
| C1B00:64 | Steering Angle Sensor: Signal Plausibility Failure | The SASM monitors the input and output of the internal sensorsand compares this information to other inputs to determine sensorvalidity. This DTC sets if the internal SASM sensors do not agreewith other inputs. |
| C1B00:81 | Steering Angle Sensor: Invalid Serial Data Received | This DTC sets if the SASM receives invalid serial data from outside sources. |
| C1B00:85 | Steering Angle Sensor: Signal Above Allowable Range | This DTC sets if the SASM steering angle sensor information isoutside regular measuring range of -1,080 degrees to +1,080 degrees. |
| U1000:00 | Solid State Driver Protection Active - Driver Disabled: No Sub Type Information | The SASM uses solid state drivers to control various outputs. When an overload occurs on any of these drivers, the SASM disables the output. This DTC sets if one of the following conditions exists: the high power current is more than 44.75A and less than 56A for 5 seconds, or the SASM has detected 3 high power circuit failures within the same ignition cycle. |
| U2001:98 | Reduce System Function: Component Or System Over Temperature | This DTC sets if the clockspring tape temperature exceeds 95°C (203°F) for 10 seconds or 105°C (221°F) for less than 500 milliseconds. |
| U2002:98 | Switch: Component Or System Over Temperature | This DTC sets if the high power circuit FET temperature exceeds 115°C (239°F) for 10 seconds or 125°C (257°F) for less than 1 second |
| U210A:02 | Temperature Sensor: General Signal Failure | This DTC sets due to an internal short to ground or short to voltage which causes an over-temperature condition in the clockspring tapecircuits. |
| U3000:1E | Control Module: Circuit Resistance Out Of Range | This DTC sets if the current on the clockspring tape high power circuit is between 8A and 17A and the resistance ratio crosses the upper or lower threshold. |
| U3000:42 | Control Module: General Memory Failure | This DTC sets due to an internal failure of the SASM. |
| U3000:45 | Control Module: Program Memory Failure | This DTC sets due to an internal failure of the SASM. |
| U3000:49 | Control Module: Internal Electronic Failure | This DTC sets due to an internal failure of the SASM. |
