What is a Daihatsu Gran Move G301 airbag control unit?
The Daihatsu Gran Move G301 airbag control unit is the central safety unit of the Supplemental Restraint System (SRS), which activates all occupant restraint systems such as airbags in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the correct functioning of all airbag modules in the vehicle. This is essential for an efficient Daihatsu Gran Move G301 airbag control unit repair.
This SRS unit is compatible with Daihatsu Gran Move G301 models from 1997 to 2002, particularly with the 1.6-liter gasoline engine (engine code HDEP). The system is permanently powered and uses crash sensors for impact detection.
It processes fault messages and enables diagnostics via the on-board diagnostics (OBD) system. Yellow wiring harnesses indicate the secure connections to the airbag ignition system. The control unit continuously monitors circuits for short circuits or opens to prevent malfunctions.
Why is the Daihatsu Gran Move G301 airbag control unit defective?
The Daihatsu Gran Move G301 airbag control unit can be defective due to internal memory or logic errors, unstable power supplies, or communication problems with other systems. Short circuits in the airbag deployment circuit can also damage the control unit. A timely diagnosis is essential for a successful Daihatsu Gran Move G301 airbag control unit repair.
A common cause of failure is internal hardware defects or memory errors that prevent the airbag ECU from functioning properly. System voltage problems or ground faults can also lead to a malfunction. The system is designed to detect and report such irregularities.
Communication problems with other control units or the steering wheel pad can also signal a defect. These errors often prevent the airbags from deploying normally and activate the warning light. A professional diagnosis is then necessary to identify the exact problem and restore safety.
Common error codes for Daihatsu Gran Move G301 airbag control unit repair
Specific error codes are crucial for Daihatsu Gran Move G301 airbag control unit repairs, as they provide information about the exact nature of the internal control unit defect. These codes cover issues ranging from initial testing to persistent internal hardware or communication errors, enabling targeted diagnosis of the airbag ECU.
- Code 11: Initial check failed → ECU communication or system start error → Airbag ECU.
- Code 16: Internal error → System voltage or internal control unit error → Airbag ECU.
- Code 17: Diagnostic Error → Airbag ECU function diagnosis failed → Airbag ECU.
- Code 18: Internal error permanent → Internal defect in the airbag ECU → Airbag ECU.
- Code 21: Communication error permanent → problem between control units → airbag ECU.
- Code 22: Internal memory error permanent → Internal memory defect in the airbag ECU → Airbag ECU.
- Code 23: Short circuit or ground fault permanent → Short circuit in the driver airbag ignition circuit → Airbag ECU.
- Code 24: Internal diagnostic test failed permanent → Airbag ECU internal diagnostic test failed → Airbag ECU.
- Code 31: Permanent logic error → Control unit internal logic error → Airbag ECU.
- Code 32: Memory defect permanent → Defect in the airbag ECU memory → Airbag ECU.
- Code 33: Communication error permanent → Problem to steering wheel pad → Airbag ECU.
- Code 34: Connection error permanent → Airbag control error → Airbag ECU.
- Code 41: Circuit problems persistent → Problems in the airbag ECU circuit → Airbag ECU.
- Code 42: Incorrect voltage permanent → Airbag ECU detects incorrect voltage → Airbag ECU.
- Code 43: Diagnostic malfunction permanent → Diagnostic function of the control unit faulty → Airbag ECU.
- Code 44: Permanent hardware defect → Airbag ECU Hardware defect → Airbag ECU.
- Code 61: Configuration error → Control unit configuration faulty → Airbag ECU.
- Code 62: Incorrect response permanent → Airbag ECU does not respond correctly → Airbag ECU.
What part numbers are available for the Daihatsu Gran Move G301 airbag control unit repair?
For the Daihatsu Gran Move G301 airbag control unit repair, there are currently no explicitly verified OEM part numbers available that meet the strict criteria of official manufacturer catalogs or independent sources. Searches in professional databases and forums did not yield any clear and confirmed part numbers for this specific airbag control unit for the Daihatsu Gran Move G301.
Extensive research in spare parts databases such as TecDoc, manufacturer information from Autoliv and Bosch, and specialized forums failed to provide any specific, confirmed OEM numbers for the airbag control unit of the Daihatsu Gran Move G301. This significantly complicates identification by part number, making precise matching difficult.
If you need a precise part number for your Daihatsu Gran Move G301 airbag control unit repair, we recommend contacting an authorized Daihatsu dealer directly or using specialized OEM parts catalogs like TecAlliance to ensure compatibility. Replacing defective control units is often only possible with used spare parts, as new units are rarely available on the market.
