C1405-TRANSFER CASE RANGE POSITION SENSOR CIRCUIT HIGH (CONTINUED) For a complete wiring diagram Refer to Section 8W • When Monitored: • Set Condition: Possible Causes INTERMITTENT TRANSFER CASE RANGE POSITION SENSOR CIRCUIT HIGH (K504) DRIVETRAIN 5 VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE (T313) MODE SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE (T313) MODE SENSOR SIGNAL CIRCUIT OPEN (K594) DRIVETRAIN SENSOR RETURN CIRCUIT OPEN TRANSFER CASE MOTOR FINAL DRIVE CONTROL MODULE Diagnostic Test 1. T-CASE POSITION SENSOR VOLTAGE ABOVE 4.8 VOLTS Ignition on, engine not running. With the scan tool under Data Display, read the T-Case Position Sensor voltage. Is the voltage above 4.8 volts? Yes >> Go To 2 No >> Go to 8 2. (K504) DRIVETRAIN 5 VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Transfer Case Motor harness connector. Turn the ignition on. Measure the voltage of the (K504) Drivetrain 5 Volt Supply circuit. Is the voltage above 5.5 volts? Yes >> Repair the (K504) Drivetrain 5 Volt Supply circuit for a short to voltage. Perform the TRANSFER CASE VERIFICATION TEST- No >> Go to 3 21 - 910 TRANSFER CASE - ELECTRICAL DIAGNOSTICS WK |
