Test Description
WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 4: This step tests for a short to ground in the ignition 1 voltage circuit.
- 5: This step test for a fault in the ignition 1 voltage circuit.
- 6: This step test for high resistance. Three ohms or more can cause can cause a driveability condition.

| 1 | Did you perform the Diagnostic System Check - Engine Controls? | - | Go to Step 2 | Go to Diagnostic System Check - Engine Controls |
| 2 |
IMPORTANT:
Do not perform this diagnostic procedure if you were not sent here from a misfire DTC or the Engine Cranks but Does Not Run diagnostic. Attempt to start the engine.Does the engine start and run? |
- | Go to Step 3 | Go to Step 4 |
| 3 | Observe the misfire current counters with a scan tool. Does the scan tool display any misfire current counters incrementing? |
- | Go to Step 7 | Go to Intermittent Conditions |
| 4 | Inspect the fuse that supplies the ignition 1 voltage to the ignition coil. Is the fuse open? |
- | Go to Step 9 | Go to Step 5 |
| 5 |
|
- | Go to Step 6 | Go to Step 8 |
| 6 | Test for high resistance in the ignition 1 voltage circuit of the ignition coil. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Is the resistance more than the specified value? |
4 ohms | Go to Step 10 | Go to Step 11 |
| 7 | Test for an intermittent and for a poor connection at the ignition coil. Refer to Testing for Intermittent Conditions and Poor Connections
and Connector Repairs
in Wiring Systems. Did you find and correct the condition? |
- | Go to Step 12 | Go to Step 11 |
| 8 | Repair the open in the ignition 1 voltage circuit of the coil. Refer to Wiring Repairs
in Wiring Systems. Did you complete the repair? |
- | Go to Step 12 | - |
| 9 |
IMPORTANT:
The ignition 1 voltage circuit is shared with other components. Review the electrical schematic and diagnose the shared circuits and components. Repair the short to ground in the ignition 1 voltage circuit of the ignition coil. Refer to Wiring Repairs
in Wiring Systems.Replace the fuse.Did you complete the repair? |
- | Go to Step 12 | - |
| 10 | Repair the high resistance in the ignition 1 voltage circuit of the ignition coil. Refer to Wiring Repairs
in Wiring Systems. Did you complete the repair? |
- | Go to Step 12 | - |
| 11 | Replace the ignition coil. Refer to Ignition Coil(s) Replacement
. Did you complete the replacement? |
- | Go to Step 12 | - |
| 12 |
|
- | Go to Step 13 | Go to Step 2 |
| 13 | Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed? |
