Dodge Ram Truck 1500-2500-3500. Manual — part 539

PASSENGER SQUIB 1 SHORT TO BATTERY (CONTINUED)

For the Air Bag System circuit diagram (Refer to 8 - ELECTRICAL/RESTRAINTS - SCHEMATICS AND DIA-
GRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the voltage on the Passenger Squib 1
circuits.

•

Set Condition:
When the ORC has detected voltage on the Passenger Squib 1 circuits.

DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following
test.

NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must
be disconnected.
Select Active or Stored DTC.

CHECK FOR SHORTED SQUIB CIRCUITS IN PASSENGER AIRBAG

WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the Passenger Airbag Squib connector.

WARNING: To avoid personal injury or death, do not place an
intact undeployed airbag face down on a hard surface, the airbag
will propel into the air if accidentally deployed.

NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool to the Passenger Airbag Squib connector.

WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active ORC DTC’s.

Does the scan tool display: PASSENGER SQUIB 1 SHORT TO
BATTERY?

Yes

>> Go To 3

No

>> Replace the Passenger Airbag in accordance with the Ser-

vice Information.

Perform ORC VERIFICATION TEST - VER 1

3.

CHECK PASSENGER SQUIB 1 LINE 2 CIRCUIT AND PASSENGER SQUIB 1 LINE 1 CIRCUIT FOR A
SHORT TO BATTERY

WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the 8443 Load Tool from the Passenger Airbag Squib con-
nector.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool ORC Adaptor to the ORC connector.

Measure the voltage of the Passenger Squib 1 Line 2 circuit between
the Passenger Airbag Squib connector and ground.

Measure the voltage of the Passenger Squib 1 Line 1 circuit between
the Passenger Airbag Squib connector and ground.

Is there any voltage present on either circuit?

Yes

>> Repair the Passenger Squib 1 circuits with voltage present for a short to battery.

Perform ORC VERIFICATION TEST - VER 1

No

REPLACE THE ORC

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes before proceeding.

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to
take the proper precautions can result in accidental airbag deployment and personal injury or death.

NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must
be disconnected.

Repair

Replace the ORC in accordance with the Service Information.

Perform ORC VERIFICATION TEST - VER 1

5.

STORED ORC DTC

With the scan tool, record and erase all DTC’s from all Airbag System Modules.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or
contaminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
With the scan tool monitor active codes as you work through the following steps.

Wiggle the wiring harness and connectors of the related airbag circuit or component.

If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

If only stored codes return continue the test until the problem area has been isolated.

In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

Are any ACTIVE DTCs present?

Yes

>> Select the appropriate diagnostic procedure from the Table of Contents in this section.

No

>> No problem found at this time. Erase all codes before returning vehicle to customer.
