Rear Drive Axle and Differential

Transcription

1 Published: Mar 30, 29 Drive Axle and Differential Principle of Operation For additional, refer to section Drive Axle/Differential of the workshop manual. Inspection and Verification 1. Verify the customer concern. 2. Confirm which, if any, warning lights and/or messages were displayed on the instrument cluster. For a list of messages, refer to the relevant section of the workshop manual. 3. Visually inspect for obvious mechanical or electrical faults. Mechanical Differential oil leakage Sensor installation Electrical Fuse(s) Wiring harness physical damage or water ingress Loose or corroded electrical connectors Controller area network (CAN) circuits Sensors 4. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. 5. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index. Make sure that all DTCs are cleared following rectification. Symptom Chart Symptom Running at reduced capability with fault present Possible message fault Possible other warnings Possible causes Action Driveline overheat warning lamp /driveline fault warning lamp Water ingress to wiring harness or connectors Reduced capability Differential increased tolerances Internal fault control module fault ( Visually inspect the wiring harness and connectors for water ingress. Refer to the warranty policy and procedures manual if a module is suspect. landrovertechinfo.com/ /frmviewit.js 1/5

2 control module) overheat Overheat Slow Down Driveline overheat warning lamp Oil level incorrect Oil level incorrect specification Sensor fault Internal fault Check for correct oil quantity and specifications. Refer to the relevant section of the workshop manual. DTC index NOTE: NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra read by the manufacturer-approved diagnostic system). Intermittent faults may cause DTCs to be logged, however some DTCs may be cleared during an ignition off, ignition on cycle. Carry out a road test (if safe to do so), check the functionality of the system and retrieve any DTCs before turning the ignition off. DTC Description Possible causes Action P0562- System Voltage Low voltage supply below 9V Check the charge condition, refer to the electrical guides and check the actuator sensor circuit, repair as necessary P0563- System Voltage High voltage supply below 16V Check the charging circuit and condition P0604- Module Random Access Memory (RAM) Error - no sub type renew the.
