CHART C-2B IDLE STOP SOLENOID (VIN H & 6)

Circuit Description:
An Idle Stop Solenoid is used to increase throttle opening during certain deceleration modes and when the A/C is "ON". The solenoid is controlled by a relay which has two sets of contacts. Control of the relay is by the ECM which completes a ground to energize the solenoid. When relay is energized, throttle opening is increased only if A/C is "ON". When relay is de-energized a fixed throttle opening is maintained on deceleration regardless of A/C position.

Chart Description:
1. Checks for normal operation of solenoid. With key "ON" engine not running solenoid plunger should extend.
2. Checks for normal solenoid plunger retraction if "test" terminal is grounded.
