  No
  - Repair the (F944) Ignition Voltage Supply circuit for an open or high resistance.
  - Perform the Electronic Steering Lock (ESL) Verification Test. Refer to ELECTRONIC STEERING LOCK (ESL) VERIFICATION TEST .
CHECK (A910) BATTERY SUPPLY CIRCUIT SHORTED TO (F944) IGNITION VOLTAGE SUPPLY CIRCUIT
1. Turn the Ignition Switch OFF.
2. Remove fuses F67 (15A) and F23 (10A).
3. Measure the resistance between the (A910) circuit and the (F944) circuit at the ESL Module harness connector.
  Is there continuity between the (A910) circuit and the (F944) circuit?
  
  Yes
