Circuit/System Testing
- Verify that DTC P0562 is set as current.
- Engine running, measure the voltage at the battery terminals and compare it with the Ignition 1 Signal parameter. The battery and Ignition 1 signal readings do not differ more than 2 volts.
- If greater than the specified value, test the Ignition 1 and ground circuits for an open/high resistance.
- Ignition 1 signal 4.3L X1 terminals 19 and 73.
- Ground circuit 4.3L X2 terminal 73.
- Ignition 1 signal V8 gas engines X1 terminals 19 and 47.
- Ground circuit V8 gas engines X1 terminal 73.
- Ignition 1 signal 6.6L X1 terminal 76 and X2 terminal 21.
- Ground circuits 6.6L X2 terminals 2-4 and 6.
