CHECK FOR THE (K51) ASD RELAY CONTROL CIRCUIT OPEN INTERMITTENTLY
1. Ignition off.
2. Remove the ASD Relay.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance of the ASD Relay Control circuit while wiggling the wiring harness and connectors between the PCM and the ASD Relay connector.
  Did the resistance go above 5.0 Ohms at any time while wiggling the wiring harness and connectors?
  
  Yes
  - Repair the ASD Relay Control circuit for an intermittent open.
