Circuit/System Testing
WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- Verify DTC P0563 is set as current.
- If the DTC is history, refer to CHARGING SYSTEM TEST .
- Engine running, measure the voltage at the battery terminals and compare it with the scan tool ECM Ignition 1 Signal parameter. Verify that battery terminal and ignition 1 signal readings do not differ more than 2.0 volts.
- If greater than specified value, test the ignition 1 circuits X2 terminal 5, X2 terminal 54 and ground circuits X2 terminal 1, X2 terminal 2 and X2 terminal 4 for open/high resistance.
- If the circuits test normal, replace the ECM.
