Retrieving Codes

NOTE: Fault codes are erased when ignition is turned off. Drive vehicle, and perform self-test before turning ignition off. Fault codes can be retrieved one at a time. Correct first code retrieved, then drive vehicle and retest for additional codes.

If using Multi-Use Tester (09391-33002) to retrieve fault codes, connect tester to TCU test connector (located in fuse box at left kick panel) and cigarette lighter socket. See Fig 1 . If using analog voltmeter to retrieve codes, connect voltmeter to TCU test connector. Run engine until normal operating temperature is reached. Drive vehicle, allowing vehicle to cycle through all shift conditions.

NOTE: When using multi-use tester, refer to manufacturer instructions for fault code display information.

Read fault codes on multi-use tester, or if using voltmeter, count needle sweeps. Voltmeter needle sweeps represent on-off voltage signals, which can be used to identify fault codes. See Fig 2 -Fig 5 .
