Retrieving Codes
- Connect a jumper wire between terminal "A" (ground) and terminal "C" of Data Link Connector (DLC), or between terminal D16 (ground) and terminal D2 of SSS control module connector. See Fig 1 or Fig 2
. Turn ignition on. Observe error light on SSS control module, next to connector.
- Light will be on for 7.5 seconds, indicating self-test is in progress. Code sequence will then start with Code 12, which is flashed 3 times. This marks beginning of sequence. Code 12 is signalled by: flash, a short pause, flash, flash, and a long pause.
- If codes are stored, they will be flashed in ascending order (code of lowest numeric value is flashed first). Each code is flashed 3 times before next code is flashed. When all codes have been flashed, Code 12 will be flashed again, indicating sequence is starting over. If no codes are stored, only Code 12 will be flashed.
- If test jumper wire is disconnected during sequence, sequence will be aborted. Start procedure again from beginning. For interpretation of codes, see CODE INTERPRETATION table. To repair indicated fault, see TROUBLE CODE CHARTS .
