Eldorados, Sevilles, and Allantes:

If the column wiring and keys are OK, replace the starter enable relay, P/N 25609047 (1992 Eldorados and Sevilles should use P/N 14100455).

Parts are currently available from GMSPO.

Refer to Section 9D or Section 8A, Cell 133, of the appropriate Service Information Manual for the location of the starter enable relay.

In these cases, the customer may indicate that rapidly cycling the key from off to crank will allow the vehicle to crank and start. The three minute wait timer will not delay a restart. The security telltale will bulb check normally and will not illuminate to indicate a PASSKey problem.


4. PASSKey CIRCUITS KEY INPUT

If the condition remains, disconnect the PASSKey module and check the resistance between A6 and B2 with the key in the ignition. The resistance should be within 10 ohms of the key pellet resistance as checked with an ohmmeter. Check wiring between the column and the PASSKey module while watching the resistance between A6 and B2. If the resistance changes, recheck for intermittent connection at the lock cylinder to the key, shorts or opens in the column, at the connector at the base of the column, or between the column and PASSKey module in circuits 1073 and 1074. See notes under step 2 for diagnosis of telltale, message and wait timer moding for opens, shorts to ground and improper resistance.

5. PASSKey MODULE WIRING

Check the power and ground to the PASSKey module. Intermittent power or ground at the module may cause the security telltale to bulb check multiple times.
