## Power Door Lock Control Circuit Input Test

1. | Remove the gauge assembly.

2. | Disconnect the gauge assembly connectors. NOTE: All connectors are wire side of female terminals.

3. | Inspect the connector and socket terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to 4.

4. | With the connectors still disconnected, make these input tests at the connectors. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, go to 5.
Cavity | Wire | Test condition | Test: Desired result | Possible cause if result is not obtained
--- | --- | --- | --- | ---
A1 | WHT/RED | Under all conditions | Check for voltage to ground: There should be battery voltage. | Blown No. 8 (15 A) fuse in the under-hood fuse/relay box An open in the wire
A2 | YEL | Ignition switch ON (II) | Check for voltage to ground: There should be battery voltage. | Blown No. 16 (7.5 A) fuse in the under-dash fuse/relay box An open in the wire
A9 | BLK | Under all conditions | Check for continuity to ground: There should be continuity. | Poor ground (G401) An open in the wire
A19

5. | Reconnect the connectors, and make these input tests at the connector. If any test indicates a problem, find and correct the cause, then recheck the system. If all input test prove OK, the gauge assembly must be faulty; replace it.
