Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Verify that ECM DTC P0606 is not set.
- If the DTC is set, Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- Ignition OFF, disconnect the K59 starter generator control module X3 connector and the K20 ECM X1 connector.
- Test for less than 1 Ω between the serial data circuits listed below:
- K59 starter generator control module X3 connector terminal 16 and K20 ECM X1 connector terminal 36
- K59 starter generator control module X3 connector terminal 17 and K20 ECM X1 connector terminal 37
- If greater than the specified range, test the serial data circuit for an open/high resistance condition. If the circuit tests normal, replace the K20 ECM.
- If the DTC resets, program the K59 starter generator control module. If the DTC resets, replace the K59 starter generator control module.
