DTC P117:

Shift Solenoid Circuit:

CIRCUIT DESCRIPTION:
This diagnostic test monitors the Shift "A" and Shift "B" outputs from the PCM and increments a counter when the output is different than what is commanded. When the counter reaches 10, Code 117 is set. If at any time before the counter reaches 10 the output is the same as what is commanded, the counter will be reset to zero.

NOTES ON FAULT TREE:
12. Checking if Shift "A" solenoid is functioning properly using PCM output and PCM status light.
13. Checking if Shift "B" solenoid is functioning properly using PCM output and PCM status light.
14. Checking if PCM is receiving voltage.
15. Checking for an open or short to ground on CKT 750 outside of transaxle.
16. Checking CKTs 750 and 581 or Shift "A" solenoid for open.
17. Checking for a short to ground. If resistance is 1000 ohms or less, the short is inside the transaxle. If resistance is greater than 1000 ohms, the short is between "C111" and the PCM.
18. Checking CKTs 750 and 582 or Shift "B" solenoid for an open.
19. Checking for a short to ground. If resistance is 1000 ohms or less, the short is inside the transaxle. If resistance is greater than 1000 ohms, the short is between "C111" and PCM.
