Default RE: Code Repair Information

You didn't list what you were driving so here are the basics.

DTC B2757, B2762, B2767, or B2772
Circuit Description
The memory function switches are normally open and are wired to the driver door switch assembly (DDSA). When a memory recall switch is pressed, the switch pulls the 5 volt signal circuit from the DDSA low. The DDSA senses that a memory recall signal was pulled low and a class2 message is sent out identifying that the circuit is active.
Conditions for Running the DTC
The DDSA must be powered and can not have B1328 -- Battery Voltage High or B1327-Battery Voltage Low as active DTCs for this DTC to set.
Conditions for Setting the DTC
If a memory recall switch circuit is active for more that 30continuous seconds, the circuit will be considered shorted, and the DDSA will set this DTC.
Action Taken When the DTC Sets
The DDSA ignores the invalid switch input from the memory function switch and will not respond to it. The DDSA will respond to all other valid switch inputs.
Conditions for Clearing the DTC
The DTC automatically clears when the switch circuit setting the DTC is no longer active.

DTC B0028, B0029, or B0030
Circuit Description
The passenger side deployment loop consists the following components:[align=left]



•
An inflatable restraint side impact module-RF [/align][align=left]



•
The inflatable restraint side impact module wiring harness [/align][align=left]



•
The side impact module-RF high circuits [/align][align=left]



•
The side impact module-RF low circuits [/align]A shorting bar is used within the side impact module-RF connector. The shorting bar will short together the side impact module-RF high circuit, and the side impact module-RF low circuit when the connector is disconnected. This helps prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force, the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop. This flow of current will deploy the side impact module-RF. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored in memory.
Conditions for Running the DTC
Ignition1 voltage is within the normal operating voltage range.
Conditions for Setting the DTC[align=left]



•
DTCB0028 will set when the side impact module-RF deployment loop resistance is less than 1.3ohms for 500milliseconds. [/align][align=left]



•
DTCB0029 will set when one of the following conditions occurs: [/align][align=left]



-
Side impact module-RF high circuit is less than 2.4volts and the side impact module-RF deployment loop is more than 6ohms for 500milliseconds. [/align][align=left]



-
Side impact module-RF deployment loop resistance is more than 4.8ohms for 500milliseconds. [/align][align=left]



•
DTCB0030 will set when one of the following conditions occur: [/align][align=left]



-
Side impact module-RF high and/or low circuits is short to ground or short to voltage for 500milliseconds. [/align][align=left]



-
Side impact module-RF high circuit is less than 2.4volts and side impact module-RF deployment loop resistance is less than 6ohms for 500milliseconds. [/align]
Action Taken When the DTC Sets
The SDM commands the AIR BAG indicator ON via Class2 serial data.
Conditions for Clearing the DTC[align=left]



•
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used. [/align][align=left]



•
A history DTC will clear once 255 malfunction free ignition cycles have occurred. [/align]
Diagnostic Aids
The following are possible causes of the malfunction:[align=left]



•
A short between the side impact module-RF high and low circuits. [/align][align=left]



•
An open or a high resistance in the side impact module-RF high or low circuits. [/align][align=left]



•
A short to ground or a short to voltage in the side impact module-RF high or low circuits. [/align][align=left]



•
The side impact module-RF connector [/align][align=left]



•
The SDM connector [/align][align=left]



•
A malfunctioning side impact module-RF [/align][align=left]



•
A malfunctioning SDM [/align]Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.


DTC B0249, B0269, B0409, B0419, or B0429
Circuit Description[align=left]



•
B0249 Mode actuator range error [/align][align=left]



•
B0269 Recirculation actuator range error [/align][align=left]



•
B0409 Left air temperature actuator range error [/align][align=left]



•
B0419 Right air temperature actuator range error [/align][align=left]



•
B0429 Auxiliary air temperature actuator range error [/align]The actuator is an electronic stepper motor. The HVAC control module (IPM) supplies power and ground to the actuator. The IPM controls the direction of the actuator by changing the polarity of the control circuits. When the actuator reaches its desired position, both circuits are fixed to the same value (9.5 to 12volts). The IPM determines the door position by counting pulses (voltage fluctuations) caused by the brush to commutator action generated during normal motor operation. The IPM monitors a voltage drop across an internal resistance to detect the pulses. The IPM converts the pulses to counts with a range of 0 to 255 counts.
When a calibration or recalibration procedure is performed, the IPM calculates the door travel range. The IPM commands the actuator to each extreme position and counts the total number of pulses. The IPM compares the total number of pulses to calibrated limits. If the total pulse count is less than or equal to the maximum calibrated limit and greater than or equal to the minimum calibrated limit, then the calibration is considered successful.
Conditions for Running the DTC
The IPM will run the DTC when either of the following conditions are met.[align=left]



•
The IPM has completed a calibration/recalibration of the actuator. [/align][align=left]



•
The IPM commands the actuator to move. [/align]
Conditions for Setting the DTC
The IPM will set this DTC if either of the following conditions are true.[align=left]



•
The actuator fails calibration/recalibration due to an over travel or under travel condition. (The IPM does not detect the calibrated number of total pulse counts during a travel range check.) [/align][align=left]



•
The IPM determines that the actual door position does not equal the commanded door position. (The IPM commands the door to move but does not see the expected number of pulses between positions.) [/align]
Action Taken When the DTC Sets[align=left]



•
The IPM will attempt to make use of whatever range is still available. [/align][align=left]



•
The IPM will recalibrate the actuator each time the ignition switch is turned ON. [/align]
Conditions for Clearing the MIL/DTC[align=left]



•
The DTC will become history if the IPM no longer detects a failure. [/align][align=left]



•
The history DTC will clear after 50 fault free ignition cycles. [/align][align=left]



•
The DTC can be cleared with a scan tool. [/align]
Diagnostic Aids[align=left]



•
Inspect the appropriate actuator door and actuator for the following conditions: [/align][align=left]



-
A misaligned actuator. Refer to one of the following: [/align][align=left]



•
Mode Actuator Replacement [/align][align=left]



•
Air Temperature Actuator Assembly Replacement [/align][align=left]



•
Air Temperature Actuator Replacement - Left [/align][align=left]



•
Recirculation Actuator Replacement [/align][align=left]



-
Broken or binding linkages or actuator door [/align][align=left]



-
Obstruction that prevents the actuator door from operating within its full range of motion [/align][align=left]



-
Missing seals to the actuator door [/align][align=left]



-
Misaligned seals to the actuator door [/align][align=left]



•
Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems[/align]
