What Does P1715 Mean?
Shift Solenoid B (SSB) has failed an inductive signature test, indicating abnormal electrical characteristics in the solenoid coil or circuit. Similar to SSA testing, this detects internal electrical or mechanical faults in the solenoid.
Common Causes
45%
Failed shift solenoid B with internal coil damage or short
25%
Contaminated transmission fluid causing solenoid mechanical binding
15%
Worn or damaged transmission valve body affecting solenoid operation
10%
Internal wiring harness fault within transmission
5%
Transmission control module malfunction
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition for contamination, burning, or debris
2
Step 2: Perform resistance test on shift solenoid B using manufacturer specifications
3
Step 3: Monitor solenoid operation with bidirectional scan tool control to verify mechanical response
4
Step 4: Check solenoid circuit voltage and ground at transmission connector
5
Step 5: If external tests pass, remove valve body for direct solenoid and valve body inspection
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
Shift Solenoid B (SSB) has failed an inductive signature test, indicating abnormal electrical characteristics in the solenoid coil or circuit. Similar to SSA testing, this detects internal electrical or mechanical faults in the solenoid.
The most common cause of P1715 (SSB Inductive Signature Malfunction) is: Failed shift solenoid B with internal coil damage or short
Typical repair costs for P1715 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause harsh shifting, delayed engagement, or transmission stuck in one gear. Can lead to unexpected transmission behavior that affects vehicle acceleration and control.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1715 to identify the root cause.
