DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

With CONSULT








1. Turn ignition switch "ON" and select "DATA MONITOR" mode for "ENGINE" with CONSULT.
2. Drive vehicle in "D"" position and allow the transmission to shift 1 -> 2 -> 3 ("GEAR").

With GST
1. Start engine.
2. Drive vehicle in D1 -> D2 -> D3 position.
3. Select "MODE 7" with GST.

No Tools
1. Start engine.
2. Drive vehicle in D1 -> D2 -> D3 position.
3. Perform self-diagnosis for ECM.
