What Does P1708 Mean?
An electrical short circuit has been detected in the transfer case control wiring or solenoid circuits. This prevents proper communication and control of transfer case functions.
Common Causes
35%
Shorted wiring harness or chafed wires in transfer case circuit
30%
Failed transfer case shift solenoid with internal short
20%
Water or fluid contamination in transfer case electrical connectors
10%
Damaged transfer case control module with shorted output drivers
5%
Pinched or damaged harness from undercarriage impact
Diagnostic Steps
1
Step 1: Disconnect transfer case solenoid/actuator connectors and recheck for short circuit using ohmmeter
2
Step 2: Measure resistance to ground on transfer case control circuits with components disconnected
3
Step 3: Inspect transfer case wiring harness routing for damage, especially near exhaust or moving parts
4
Step 4: Check for corrosion or water intrusion in all transfer case electrical connectors
5
Step 5: Test individual solenoids for internal short circuits using resistance measurements
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
An electrical short circuit has been detected in the transfer case control wiring or solenoid circuits. This prevents proper communication and control of transfer case functions.
The most common cause of P1708 (Transfer Box Line Short Circuit Fault) is: Shorted wiring harness or chafed wires in transfer case circuit
Typical repair costs for P1708 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transfer case may become stuck in one mode or fail to engage/disengage properly. Could cause drivetrain binding or unexpected four-wheel drive behavior.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1708 to identify the root cause.
