C211C

C211C-IGNITION RUN/START INPUT CIRCUIT LOW

For a complete wiring diagram Consult Diagrams/Electrical.





- When Monitored:
With the ignition on.

- Set Condition:
The AWD will set this DTC if the Ignition Run/Start circuit voltage is less than the expected value for more than 10 seconds.





Diagnostic Test

1. CHECK FOR ACTIVE DTC
Ignition on, engine not running.
With the scan tool, read the active DTC.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 10 seconds.
With the scan tool, read the active DTC.
Does the scan tool display this DTC as active?

Yes

- Go to 2

No

- Go to 7

2. (F202) IGNITION SWITCH OUTPUT (RUN/START)




Turn the ignition off.
Disconnect the AWD Control Module harness connector.
Ignition on, engine not running.
With a 12-volt test light connected to ground, check the (F202) Ignition Switch Output (RUN/START) circuit in the AWD Control Module harness connector.

NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Go to 3

No

- Go to 4

3. (Z908) GROUND CIRCUIT OPEN OR HIGH RESISTANCE




Turn the ignition off.
Disconnect the AWD Control Module harness connector.
With a 12-volt test light connected to B+, check the (Z908) Ground circuit in the AWD Control Module harness connector.

NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Go to 5

No

- Repair the (Z908) Ground circuit for an open circuit or high resistance.
- Perform AWD Control Module VERIFICATION TEST.AWD Control Module Verification Test.

4. (F202) IGNITION SWITCH OUTPUT (RUN/START) CIRCUIT OPEN OR HIGH RESISTANCE




Disconnect the TIPM C11 harness connector.
Connect a jumper wire between the (F202) Ignition Switch Output (RUN/START) circuit and B(+) in the TIPM C11 harness connector.
With a 12-volt test light connected to ground, check the (F202) Ignition Switch Output (RUN/START) circuit in the AWD Control Module harness connector.

NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Go to 6

No

- Repair the (F202) Ignition Switch Output (RUN/START) circuit for an open circuit or high resistance.
- Perform AWD Control Module VERIFICATION TEST.AWD Control Module Verification Test.

5. AWD CONTROL MODULE
NOTE: Before continuing, check the AWD Module harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors.
Pay particular attention to all Power and Ground circuits.

7. INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle test the wiring harness and connectors while checking for shorted and open circuits.
Using the scan tool, monitor the data related to this circuit while performing the wiggle test. Look for the data to change or for the DTC to reset.
Were there any problems found?

Yes

- Repair as necessary.
