P0350-85: Ignition Coil Primary/Secondary Circuit - Signal above allowable range: Action
- Vehicle Conditions to enable DTC Logging Strategy
- Prioritized Checks to Perform
- Check powertrain control module for additional Diagnostic Trouble Code(s) and refer to relevant DTC index. Rectify these first
- Refer to the electrical circuit diagrams and check the power and ground connections to the module
- Install new powertrain control module, only when diagnosed as failed
- 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
- Clear the DTC and retest
