Enhanced Accident Report Driver Circuit High

P2513 - ENHANCED ACCIDENT REPORT DRIVER CIRCUIT HIGH





When Monitored and Set Condition

- When Monitored: Ignition on.
- Set Condition: The Occupant Restraint Controller (ORC) periodically sends out a signal to the Powertrain Control Module (PCM). If the PCM does not receive the signal from the ORC, the PCM will set this DTC.

Diagnostic Test

1. PRE-DIAGNOSTIC CHECK OUT

NOTE: Always perform diagnostics with a fully charged battery.

NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal connections can set DTCs.

NOTE: Check for applicable TSBs related to the problem.

Turn the ignition on.
With the scan tool, read PCM DTCs.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Repair as necessary.
Perform this procedure prior to symptom diagnosis.

- Go To 2

2. CHECK FOR ACTIVE DTC
NOTE: If the PCM detects and stores a DTC, the PCM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.

NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.

With the scan tool, check the ORC for proper communication and DTCs. If there are any Occupant Restraint Controller (ORC) DTCs, repair them before continuing.
Turn the ignition on.
With the scan tool, erase PCM DTCs.
Cycle the ignition switch on and off several times, pausing for at least 10 seconds at each key off and key on.
Turn the ignition on.
With the scan tool, read PCM DTCs.
Did this DTC set again?

Yes

- Go To 3

No

- Go To 7

3. ENHANCED ACCIDENT REPORT DRIVER CIRCUIT SHORT TO VOLTAGE




WARNING: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPONENTS, THE IGNITION MUST BE TURNED OFF AND THE BATTERY MUST BE DISCONNECTED.

Turn the ignition off.
Disconnect the Occupant Restraint Controller harness connector. Occupant Restraint Controller - Removal.
Disconnect the PCM C4 harness connectors.

NOTE: Check connectors - Clean/repair as necessary.

Turn the ignition on.
Measure the voltage of the Enhanced Accident Report Driver circuit.
Is the voltage below 1.0 volt?

Yes

- Go To 4

No

- Repair the Enhanced Accident Report Driver circuit for a short to voltage.
- Perform POWERTRAIN VERIFICATION TEST - VER 2. Powertrain Verification Test

4. ENHANCED ACCIDENT REPORT DRIVER CIRCUIT SHORT TO GROUND




Turn the ignition off.
Measure the resistance between ground and the Enhanced Accident Report Driver circuit.
Is the resistance above 100 kohms?

Yes

- Go To 5

No

- Repair the Enhanced Accident Report Driver circuit for a short to ground.
- Perform POWERTRAIN VERIFICATION TEST - VER 2. Powertrain Verification Test

5. ENHANCED ACCIDENT REPORT DRIVER CIRCUIT OPEN




With the ignition off.
Measure the resistance of the Enhanced Accident Report Driver circuit from the PCM C4 harness connector to the ORC harness connector.
Is the resistance below 5.0 ohms?

Yes

- Go To 6

No

- Repair the Enhanced Accident Report Driver circuit for an open.
- Perform POWERTRAIN VERIFICATION TEST - VER 2. Powertrain Verification Test

6. ORC
WARNING: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPONENTS, THE IGNITION MUST BE TURNED OFF AND THE BATTERY MUST BE DISCONNECTED.

With the ignition off.
Replace the Occupant Restraint Controller. Occupant Restraint Controller - Removal.
Turn the ignition on.
With the scan tool, erase PCM DTCs.
Perform several engine run cycles, turning the ignition off for at least 20 seconds between each engine run cycle.
With the scan tool, read PCM DTCs.
Did this DTC set again?

Yes

- Replace and program the Powertrain Control Module. Powertrain Control Module - Removal.
- Perform POWERTRAIN VERIFICATION TEST - VER 2. Powertrain Verification Test

No

- Test Complete.

7. INTERMITTENT WIRING AND CONNECTORS
The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for a possible intermittent condition.

NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal connections can set DTCs.

NOTE: Check for any Technical Service Bulletins that may apply.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the wires while checking for shorts and/or open circuits.
Were there any problems found?

Yes

- Repair as necessary.
- Perform POWERTRAIN VERIFICATION TEST VER - 2. Powertrain Verification Test

No

- The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for a possible intermittent condition.
