Diagnostic Trouble Code (DTC) Displaying
The Air Suspension system has an internal clock to prevent overheating if the compressor assembly is running for a prolonged period of time. If the system overheats, all leveling function stops until the system cools down. During this time, the indicator LED on the air inflator switch will be quickly flashing at a constant rate.
The other three diagnostic trouble codes are displayed with a blink code on the inflator switch LED. The Air Suspension Compressor Assembly shall begin to indicate the code when the condition to cause the code becomes current.
The number of the fault code shall be represented by the number of flashing pulses on the inflator switch LED. The flashing pulses shall have a repetition rate of 0.5 seconds and each code shall be separated by a 3.0 second delay. All codes shall be flashed in the order of occurrence of the fault. The blink code shall take priority over other processes that have access to the inflator switch LED. Refer to the following:
• DTC 001
• DTC 002
• DTC 003

DTC 001 System Disabled Information Stored

The air suspension compressor assembly monitors the calibrations in the electrically erasable programmable read-only memory (EEPROM). The module also monitors the compressor, solenoids and internal wiring for faults.

Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

2004 Buick Rainier code p0446:

I'm not sure what part to buy or where to find it. Can't find this answer anywhere online. Please help. This is code p0446 and non other.

Connect white (test lead) and black (ground lead) wires that are branched from harness approximately eight inches from ECM. After leads are grounded, the "Check Engine" light will flash the diagnostic trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.I-MARK 84-85

Connect male and female test leads taped into wire harness near ECM. After leads are connected, the "Check Engine" lamp will flash the trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.
86-87 Impulse located near the ECM connector, is used to actuate the Engine Control Module (ECM) trouble code memory within the module. Two terminals (A and C) of this connector are used to activate the diagnostic trouble code system in the ECM. With the ignition switch turned On, engine Off, connect a jumper wire between terminals A and C. The "Check Engine" lamp will begin by flashing a DTC 12. DTC 12 = flash, pause, flash, flash. There will be a longer pause and a code 12 will repeat two more times. This code indicates the self-diagnostic system is operating. The cycle will then repeat until the engine is started or the ignition is switched Off. In most cases, DTC's will be checked with the engine running since no DTC's other than DTC 12 or 51 will be present without the engine running. Remove jumper wire from ALDL connector before starting engine. Reconnect jumper wire after engine is running.

Throttle Body Fuel Injection

The ECM test connection is located under the center console.
A built-in, self diagnostic system will identify problems in the throttle body fuel injection system. When a problem is detected, the diagnostic system will illuminate the "Check Engine" light.
When the engine is started, the Check Engine light should turn off.. If the light remains lit, the self diagnostic has detected a problem. To determine where the problem exists, ground the "Test" terminal of the connector with the ignition On, engine Off and watch the check engine light. Each DTC will flash three times (lowest to highest).

Error Code: P2314
Description:
Ignition coil secondary, No. 5 circuit malfunction.
Possible causes:
- Faulty igniter No. 5.
- Connector of igniter No. 5 is disconnected.
- Wiring.
- ECM.

DTC P1275 - Acceleration Position Sensor 1 Circuit Malfunction
The acceleration position (AP) sensor circuit provides a voltage signal relative to acceleration pedal angle. The acceleration pedal angle (AP1) will vary about 13% at idle position to about 87% at wide open throttle (WOT). This code detects a continuous short to ground or high in either the circuit or the sensor.


Conditions for setting the DTC:
* The Ignition is "ON".
* The acceleration pedal angle is less than 2.5% or more than 97% for 12 counts within 500 test samples (15.6 m sec ).

Action Taken When the DTC Sets:
* The PCM will store condition which were present when the DTC was set as Freeze Frame and in the Failure Records data.

Conditions for Clearing the MIL/DTC:
* The PCM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
* A history DTC P1275 will clear after 40 consecutive trip cycle during which the warm up cycles have occurred without a fault.
* DTC P1275 can be cleared using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed.



Diagnostic Aids
An intermittent may be caused by the following:
* Poor connections.
* Mis routed harness.
* Rubbed through wire insulation.
* Broken wire inside the insulation.

Check for the following conditions:
* Poor connection at PCM-Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
* Damaged harness-Inspect the wiring harness for damage. If the harness appears to be OK, observe the APP sensor 1 display on the Tech 2 while moving connectors and wiring harnesses related to the sensor.

A change in the display will indicate the location of the fault. If DTC P1275 cannot be duplicated, the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set.

If it is determined that the DTC occurs intermittently, performing the DTC P1275 Diagnostic Chart may isolate the cause of the fault.


Referential sensor location.

it is an obdII code reader. the plug that the code scanner ,reader, is under the dash next to the hood release latch its a black plug just to the left

The location of WHAT???

Diagnostic Test Code (DTC) P1250 is a manufacturer - specific code which has a general description of "Pressure Regulator Control (PRC) Solenoid Circuit Malfunction".

The PCM monitors input voltage at Pin number 44 when the ignition is turned on. DTC P1250 sets when less than .44 volts are present. The possible causes are:
> PRC Valve malfunction (open or shorted internally)
> Open or short circuit between the PRC valve and the PCM (control circuit)
> Open or short circuit in the solenoid ignition voltage supply circuit
> Failed PRC valve (stuck open)
> Malfunctioning PCM

HI, the DTC your Astro has set POO59 is set when the computer doesn't see the oxygen sensor heating up fast enough. This DTC is for the bank 2 sensor 1 oxygen sensor. I have rarely come across and other failure for this code other then the O2 its self. I would recommend to my customer to replace this sensor. Good luck and happy motoring
