EATX Output Open Load

EATX OUTPUT OPEN LOAD

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

With the ignition off.

- Set Condition:

If the Integrated Power Module (IPM) detects a open or short to battery condition on the Ignition Unlock/Run/Start circuit. This condition must be present for a least one second.

Diagnostic Test

1. INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, record and erase IPM DTC's.

Turn the ignition off.

With the scan tool, read active IPM DTCs.

Does the scan tool display: Trans Ignition Feed Open or Short To BATT?

Yes

- Go To 2

No

- The condition that caused this DTC to set is not currently present. Using the wiring diagram as a guide, inspect for chafed, pierced, pinched, and broken wires in the related wiring and connectors and pushed out terminals in the related connectors.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

2. PCM

Turn the ignition off.

Disconnect the PCM C1 harness connector.

Measure the voltage between the (F1) Ignition Unlock/Run/Start circuit and ground.

Is the voltage above 10.0 volts?

Yes

- Go To 3

No

- Go To 4

3. (F1) IGNITION UNLOCK/RUN/START CIRCUIT SHORTED TO VOLTAGE

Turn the ignition off.

Measure the voltage of the (F1) Ignition Unlock/Run/Start circuit.

Is the voltage above 0.2 volts?

Yes

- Repair the Ignition Unlock/Run/Start circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the PCM.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

4. IGNITION UNLOCK/RUN/START CIRCUIT OPEN

Turn the ignition off.

Disconnect the IPM C6 harness connector.

Measure the resistance of the (F1) Ignition Unlock/Run/Start circuit.

Is the resistance below 10K ohms?

Yes

- Repair the (F1) Ignition Unlock/Run/Start circuit for an open
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the IPM.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
