C1404- TRANSFER CASE RANGE POSITION SENSOR CIRCUIT LOW





For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    Ignition on. Battery voltage between 9.0 and 16.0 volts.

  • Set Condition:

    The TIPM detects a short to ground on the Transfer Case Position Sensor Signal circuit for 2.0 seconds.


Possible Causes
 
(T313) MODE SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
 
(T313) MODE SENSOR SIGNAL CIRCUIT SHORTED TO (K91) SENSOR GROUND CIRCUIT
 
TRANSFER CASE (4WD) SWITCH
 
TOTALLY INTEGRATED POWER MODULE (TIPM)
