1-2 / 4-5 Solenoid Circuit Short To Ground
P0753 - 1-2 / 4-5 SOLENOID CIRCUIT SHORT TO GROUND
Theory of Operation
The 1-2/4-5 Solenoid is activated when the W5AJ400 Controller determines that the transmission must shift into second or fifth gear. The solenoid is only activated during the shifting of the transmission. When the solenoid is activated hydraulic pressure is applied to the proper shift elements in the transmission to allow the desired shift. Once the shift is completed the solenoid is turned off. This detection method will only detect shorts to ground and shorted drivers when the output is off.
When Monitored and Set Condition
- When Monitored: Always monitored with system active at each ignition cycle and the solenoid is off.
- Set Condition: If the TCM detects a short to ground on the solenoid control circuit or solenoid control circuit shorted to ground in the TCM.

Diagnostic Test
1. CHECK FOR CURRENT DTC
Turn the ignition on.
With the scan tool, read Transmission DTCs.
Is this DTC present?
Yes
- For complete diagnosis of this DTC, refer to (P0753) 1-2/4-5 SOLENOID CIRCUIT. 1-2 / 4-5 Solenoid Circuit
No
- Go To 2
2. INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal connections can set DTCs.Using the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the wires while checking for shorts and open circuits.
NOTE: Check for any Technical Service Bulletins that may apply.
Were there any problems found?
Yes
- Repair as necessary.
- Perform NAG1 TRANSMISSION VERIFICATION TEST. Transmission Verification Test
No
- The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for a possible intermittent condition.
