With Major Key Off Loads As Computer-Controlled Suspension

Vehicles equipped with these features will have temporary current drains that may last up to 70 minutes after ignition switch is turned off. These drains can range from 0.1 to 20 amps if the compressor is cycling. This action can often mask a problem and must be considered when evaluating test results. To test for this kind of drain, proceed as follows.
1. Repeat Steps 1 through 5 of the Drain Testing Procedure. Drain Testing
2. Turn ignition switch to RUN for a moment and then OFF again.
3. Disconnect major key OFF load circuits.
4. Make sure interior lamp is OFF, if applicable.

Test Conclusion
The current reading (current drain) should be less than 0.05 amps. If it is higher, disconnect fuses and leads of the starter motor cutout relay to locate the problem circuit.

If the drain is less than 0.05 amps, reconnect the major key-off load circuits, turn ignition switch to RUN and then OFF, and wait 70 minutes to make sure they shut off properly. If current drain is still greater than 0.05 amps after 70 minutes, disconnect each of the components one at a time until the cause of the current drain is located.
