ASCD Pump Circuit Check
- Turn ignition switch to LOCK position. Disconnect ASCD pump harness connector. Measure resistance between specified ASCD pump connector terminals (pump side). See ASCD PUMP RESISTANCE table. See Fig 1
. If resistance is as specified, go to next step. If resistance is not as specified, replace ASCD pump.
