WHAT WE RESOLVE
1st Gen J120 (2009-2009) common module and security issues
- SRS crash-data and warning light SRS service can involve SRS Control Unit. Part numbers and crash-data workflow are confirmed for the exact year/VIN.
- Replacement module setup ECU/PCM replacement programming, BCM configuration, TCU/TCM cloning, ABS/EBCM setup are represented in the merged generation data. Rows with year ranges do not apply to every model year; verify by VIN.
- Gateway, key, and immobilizer access Gateway, key, and immobilizer procedures are represented by 2 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Lexus GX (2009-2009) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Lexus GX (2009-2009). The merged generation data includes ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS coverage. Rows marked with a year range apply only to that part of the span; unmarked rows are present across the merged generation data.
Which modules are documented for Lexus GX (2009-2009)?
The Lexus GX (2009-2009) generation currently shows 5 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit. Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 4513060490C0 - confirm for your exact year/VIN.
Can you reset the airbag module on Lexus GX (2009-2009)?
Yes. The generation data includes 1 SRS record, including SRS Control Unit. Bench reset, cloning, and replacement setup are handled after part-number review. Any SRS part number shown for this generation is planning data only - confirm for your exact year/VIN. Reference part number: 4513060490C0 - confirm for your exact year/VIN.
Do all Lexus GX (2009-2009) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2009-2009; any row that does not span all data-bearing years is printed with its year range or treated as varies by year - verify by VIN. Part numbers always require exact year/VIN confirmation before ordering, cloning, or programming.
Can you program keys or immobilizer systems for Lexus GX (2009-2009)?
Yes, where the VIN and security workflow support it. The generation data includes 2 gateway, immobilizer, or key-security records. Key records are present in the merged generation data. Security access, all-keys-lost eligibility, and add-key workflows vary by year - verify by VIN.
How long does service take for Lexus GX (2009-2009)?
Most programming, cloning, SRS, immobilizer, and key-security jobs are quoted after VIN, DTC, part number, and repair-scope review. Service time varies by module type, condition, security access, and the active mobile service path. Mail-in module intake is temporarily unavailable; do not ship a module unless support confirms next steps.
Is Lexus GX (2009-2009) service mobile or mail-in?
Mobile service covers DFW on-vehicle diagnostics, key programming, post-repair coding, and supported module work. Mail-in module intake is temporarily unavailable. We confirm the active path for your exact year/VIN before scheduling; do not ship a module unless support confirms next steps.
