Diagnostic Test

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. 1)  CHECK FOR AN ACTIVE DTC 

    Turn the ignition on.

    With the scan tool, record and erase DTCs.

    Wait 30 seconds.

    With the scan tool, read DTCs.

    Is the DTC active? 

    Yes 

    1. Go To  2).

    No 

    1. The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .
  2. 2)  CHECK PDC FUSES 

    Inspect PDC fuses #8, and #29 in the PDC.

    Is either fuse open? 

    Yes 

    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for a short to ground condition.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .

    No 

    1. Go To  3).
  3. 3)  CHECK FOR VOLTAGE ON THE (F202) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT

    Turn the ignition off.

    Disconnect the Instrument Cluster C3 harness connector.

    Turn the ignition on.

    Measure the voltage of the (F202) Fused Ignition Switch Output (Run-Start) circuit.

    Is the voltage above 10.0 volts? 

    Yes 

    1. Replace the Instrument Cluster in accordance with the service information.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .

    No 

    1. Go To  4).
  4. 4)  CHECK THE (F202, F20) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT FOR AN OPEN 
    Fig 2: Measuring Resistance Of Fused Ignition Switch Output Circuit

    Disconnect the Ignition Switch harness connector.

    Measure the resistance of the (F202, F20) Fused Ignition Switch Output (Run-Start) circuit between the Instrument Cluster C3 harness connector and the Ignition Switch harness connector.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (F202, F20) Fused Ignition Switch Output (Run-Start) circuit for an open.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .

    No 

    1. Go To  5).
  5. 5)  CHECK THE (A106) FUSED B+ CIRCUIT FOR AN OPEN 
    Fig 3: Measuring Voltage On Fused B+ Circuit
    GC0016028Courtesy of DAIMLERCHRYSLER CORP.

    Measure the voltage on the (A106) Fused B+ circuit at the Ignition Switch harness connector.

    Is the voltage above 10.0 volts? 

    Yes 

    1. Replace the Ignition Switch in accordance with the service information.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .

    No 

    1. Repair the (A106) Fused B+ circuit for an open.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1) .
