Retrieving Diagnostic Trouble Codes: Notes

NOTE: Ensure battery is in good condition and is fully charged. DO NOT start engine when retrieving codes. If codes cannot be retrieved, perform ABS WARNING LIGHT CIRCUIT and Tc TERMINAL CIRCUIT tests under SYSTEM TESTS. If problem remains, replace ABS/TRAC/VSC ECU.

Turn ignition on. Ensure ABS warning light illuminates for 3 seconds. If ABS warning light does not illuminate, see ABS WARNING LIGHT CIRCUIT under SYSTEM TESTS. If ABS warning light flashes or stays on constantly, retrieve Diagnostic Trouble Codes (DTC). See Using ABS Warning Light or Using Lexus Scan Tool .
