Symptom Chart
Condition | Actions |
---|---|
Driveline clunk - loud clunk when shifting from REVERSE to DRIVE | GO to Pinpoint Test A |

Pinpoint Tests
Normal Operation and Fault Conditions The driveline system enables the power generated by the engine and transferred through the transmission and, if applicable, transfer case, to place the vehicle in motion. Rotational torque received from the transmission or transfer case is delivered to the front and rear drive axles by way of the driveshafts. The CV joints at the ends of the shafts allow the shafts to rotate smoothly in an allowable angle plane. The rotational torque is introduced into the axle differential which drives the axles/halfshaft. Possible Sources

What Is the Master Access Code
The master access code is a factory-set five-digit entry code. You can operate the keypad with the master access code at any time. The master access code is on the owner’s wallet card in the glove box and is available from an authorized dealer.
Displaying the Master Access Code
To display the factory-set code in the information display:
Remove the rubber mat. Insert the first programmed key in the backup slot. Press the push button ignition switch once and wait a few seconds. Press the push button ignition switch again and remove the key. Within 10 seconds, place a second programmed intelligent access key in the backup slot and press the push button ignition switch.
