DTC P262B-84: Control Module Power Off Timer Performance - Signal below allowable range: Action
- Vehicle Conditions to enable DTC Logging Strategy
- Prioritized Checks to Perform
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Using the Jaguar Land Rover approved diagnostic equipment check "Network Overview" for off bus control modules
- Refer to the electrical circuit diagrams and check high speed CAN network for short circuit to ground, short circuit to power, open circuit
- Install new powertrain control module, only when diagnosed as failed. Using the Jaguar Land Rover approved diagnostic equipment, configure the powertrain control module as a new module
- The powertrain control module now has a liquid cooling system incorporated. The following care points must be followed during removal, installation of component and disconnection, connection of electrical harness connectors
- Make sure PCM side connectors are always dry
- Make sure mating PCM harness connectors are always dry
- Make sure PCM is always handled with connector facing upwards to avoid any accidental exposure of the connector to the coolant from the cooling pipe of the PCM to avoid damage to the PCM
- Make sure that the connector from the PCM (harness side) is disconnected and connected only in a dry and clean environment
