Inspection Procedure (Using the GDS)

NOTE:

When battery voltage is excessively low, diagnostic trouble codes can not be read. Be sure to check the battery for voltage and the charging system before starting the test.
Diagnosis memory is erased if the battery or the TCM connector is disconnected. Do not disconnect the battery before the diagnostic trouble codes (DTC) are completely read and recorded.

Turn OFF the ignition switch.
Connect the GDS to the data link connector on the lower crash pad.
Turn ON the ignition switch.
Use the GDS to check the diagnostic trouble code.
Repair the faulty part from the diagnosis chart.
Erase the diagnostic trouble code.
Disconnect the GDS.
