Technical Data - PTU And RDM
Power Transfer Unit (PTU) - The voltage values given below are taken with the ignition on and the engine not running.
| Expected typical voltage readings on the PTU motor and position sensor circuits | ||
|---|---|---|
| CIRCUITS | TYPICAL VOLTAGE WITH MOTOR CONNECTOR UNPLUGGED | TYPICAL VOLTAGE WITH MOTOR CONNECTOR PLUGGED IN |
| MOTOR (+) | Approximately 9.9 volts | Approximately 4.6 volts |
| MOTOR (-) | Approximately 1.5 volts | Approximately 4.6 volts |
| SENSOR SUPPLY | Approximately 7.5 volts | Approximately 4.0 volts |
| HALL EFFECT POSITION SENSOR SIGNALS | 0 volts for both | The position sensor voltage signals should be either approximately 1.6 volts or 5.3 volts depending on the motor position. |
| Both position sensor voltage signals should alternate between approximately 1.6v and 5.3v as the motor shaft rotates during a PTU shift between modes (2WD <-> AWD). | ||
Rear Drive Module (RDM) - The voltage values given below are taken with the ignition on and the engine not running.
| Expected typical voltage readings on the RDM motor and position sensor circuits | ||
|---|---|---|
| CIRCUITS | TYPICAL VOLTAGE WITH MOTOR CONNECTOR UNPLUGGED | TYPICAL VOLTAGE WITH MOTOR CONNECTOR PLUGGED IN |
| MOTOR (+) | Approximately 9.9 volts | Approximately 4.4 volts |
| MOTOR (-) | Approximately 1.2 volts | 0 volts |
| SENSOR SUPPLY | 0 volts | Approximately 7.5 volts |
| HALL EFFECT POSITION SENSOR SIGNALS | 0 volts for both | The position sensor voltage signals should be either approximately 1.6 volts or 5.3 volts depending on the motor position. |
| Both position sensor voltage signals should alternate between approximately 1.6v and 5.3v as the pulse width changes and the motor shaft rotates with the RDM clutch engaged. | ||
