Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY ACTIVE DTC
NOTE:
Ensure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.
  Does the scan tool display active B212D-13-IGNITION RUN ONLY INPUT CIRCUIT OPEN DTC?
  
  Yes
  - Go To 2.
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to Standard Procedure .
CHECK FOR ACTIVE RUN RELAY DTC
1. With the scan tool, read TIPM DTCs.
  Does the scan tool display any active TIPM Run Relay related DTCs?
  
  Yes
  - Perform the appropriate TIPM diagnostic procedures. Refer to appropriate Electrical Diagnostic Information .
  No
  - Go To 3.
INSPECT TIPM FUSE M32
1. Turn the Ignition OFF.
2. Remove and inspect the TIPM Fuse M32.
  NOTE:
  Check connectors - Clean and repair as necessary.
  
  Is the TIPM Fuse M32 open?
  
  Yes
  - Go To 4.
  No
  - Go To 6.

WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Measure the resistance of the (F100) Fused Ignition Run Control Output circuit between the TIPM Fuse M32 output terminal and ground.
  Is the resistance below 100 Ohms?
  
  Yes
  - Go To 5.
  No
  - Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
  - Replace TIPM Fuse M32.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
CHECK (F100) FUSED IGNITION RUN CONTROL OUTPUT CIRCUIT WITH ORC DISCONNECTED

1. Disconnect the ORC harness connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Adaptor (special tool #8443-24, 32-Way Adapter) to the ORC C2 harness connector.
3. Measure the resistance of the (F100) Fused Ignition Run Control Output circuit between SRS Load Tool Adaptor (special tool #8443-24, 32-Way Adapter) cavity 24 and ground.
  Is the resistance below 100 Ohms?
  
  Yes
  - Repair the (F100) Fused Ignition Run Control Output circuit for a short to ground.
  - Replace the TIPM Fuse M32.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Replace the ORC in accordance with the Service Information.
  - Replace the TIPM Fuse M32.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
CHECK TIPM FUSE M32 SUPPLY CIRCUIT VOLTAGE
1. Turn the ignition on.
2. Measure the voltage of the Ignition Run Control Output circuit between the TIPM Fuse M32 supply terminal and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  - Go To 7.
  No
  - Repair the open Ignition Run Control Output circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .

WARNING:
Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Reinstall the TIPM Fuse M32.
2. Disconnect the ORC harness connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adapter (special tool #8443-24, 32-Way Adapter) to the ORC C2 harness connector.
  WARNING:
  Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
4. Measure the voltage of the (F100) Fused Ignition Run Control Output circuit between the appropriate terminal of the SRS Load Tool Adapter (special tool #8443-24, 32-Way Adapter) and ground.
  Is the voltage above 6.0 volts?
  
  Yes
  - Replace the ORC in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Go To 8.
CHECK FOR OPEN (F100) FUSED IGNITION RUN CONTROL OUTPUT CIRCUIT

WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the TIPM C6 harness connector.
  NOTE:
  Check connectors - Clean and repair as necessary.
2. Measure the resistance of the (F100) Fused Ignition Run Control Output circuit between the SRS Load Tool Adapter (special tool #8443-24, 32-Way Adapter) cavity 24 and the TIPM C6 harness connector cavity 38.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Replace the TIPM in accordance with the Service Information.
