Fuse check
- Check for fuse blow at "IG" fuse and "Fl" fuse (1).
Are fuses in good condition? |
Go To Step 2. |
Replace fuse and check for short in circuits connected to this fuse. |

Main relay circuit check
- Turn ignition switch to OFF position.
- Remove main relay (2) from relay and fuse box.

- Check for proper connection to main relay connector at "BLK/YEL" and "BLK/RED" wire terminals.
- If OK, measure voltage between "BLK/YEL" wire terminals of main relay connector and body ground.
Is voltage 10 - 14 V? |
Go To Step 3. |
Open wire in "BLK/YEL" circuit. |

Main relay check
- Check for main relay referring to MAIN RELAY INSPECTION
.
Is main relay in good condition? |
Go To Step 4. |
Replace main relay. |

Ignition signal check
- Disconnect connectors from ECM with ignition switch turned OFF.
- Check for proper connection to ECM connector at "C46-10", "C45-23", "G04-7", "G04-6", "C45-6", "C46-6" and "C45-2" wire terminals.
- Turn ignition switch to ON position.
- Measure voltage between "C46-10" wire terminal of ECM connector and body ground.
Is voltage 10 - 14 V? |
Go To Step 5. |
Open wire in "BLK/ WHT" or "GRN" circuit. |
| 5 |
Main relay circuit check
- Turn ignition switch to OFF position.
- Install main relay to relay and fuse box.
- Measure voltage between "C45-23" wire terminal of ECM connector and body ground.
Is voltage 10 - 14 V? |
Go To Step 6. |
Go To Step 8. |
| 6 |
Main relay circuit check
- Remove ECM from vehicle body referring to ENGINE CONTROL MODULE (ECM) REMOVAL AND INSTALLATION
and connect connectors to ECM.
- Turn ignition switch to ON position.
- Measure voltage between "C45-23" wire terminal of ECM connector and body ground.
Is voltage 0 - 1 V? |
Go To Step 8. |
Go To Step 7. |
| 7 |
ECM ground circuit check
- Turn ignition switch to OFF position.
- Disconnect connectors from ECM.
- Measure resistance between each "C45-6", "C46-6" and "C45-2" wire terminals of ECM connector and body ground.
Is resistance 1 Ω or less? |
Intermittent trouble.
Check for intermittent referring to "INTERMITTENT AND POOR CONNECTION INSPECTION
."
If OK, substitute a known-good ECM and recheck. |
Open or high resistance wire in "BLK/ORN" or "BLK" circuit. |
| 8 |
Main relay circuit check
- Using service wire, ground "C45-23" wire terminal of ECM connector.
- Turn ignition switch to ON position.
- Measure voltage between each "G04-7" and "G04-6" wire terminals of ECM connector and body ground.
Is voltage 10 - 14 V? |
Intermittent trouble.
Check for intermittent referring to "INTERMITTENT AND POOR CONNECTION INSPECTION
."
If OK, substitute a known-good ECM and recheck. |
Go To Step 9. |
| 9 |
Main relay circuit check
- Turn ignition switch to OFF position.
- Measure resistance between each "G04-7" and "G04-6" wire terminals of ECM connector and "BLK/RED" wire terminal of main relay connector.
Is resistance 1 Ω or less? |
Open or high resistance wire in "BRN/WHT" circuit. |
Open or high resistance wire in "BLK/RED" circuit. |
