(1) When battery voltage is low, no detection of failure is possible. Be sure to check the battery for voltage and other conditions before starting the test.
(2) Diagnostic item is erased if the battery or the engine control module connector is disconnected. Do not disconnect the battery before the diagnostic result is completely read.
(3) Be sure to connect or disconnect the scan tool with the ignition switch turned off. If the scan tool is disconnected with the ignition switch placed in the ON position, ABS diagnostic trouble code may be stored and ABS warning lamp turned on.
