P0615-4B: Starter Relay Circuit - Over temperature: Action
- Vehicle Conditions to enable DTC Logging Strategy
- Prioritized Checks to Perform
- Refer to the electrical circuit diagrams and check the starter motor relay circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Install new starter motor relay, only when diagnosed as failed
- Refer to the electrical circuit diagrams and check the power and ground connections to the module
- Check core temperature of powertrain control module
- Using the Jaguar Land Rover approved diagnostic equipment check and install latest relevant level of software to the powertrain control module
- Clear the DTC and retest
- 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
