Inspection and verification
1. Check the validity of the customer's complaint by using the system.
2. Perform a visual inspection for obvious signs of mechanical or electrical damage.

Mechanical factors |
Electrical factors |
|
– Ignition lock cylinder – PATS key (with blue insert) – Using a key that does not belong to the PATS system – Multiple PATS keys or presence of metal objects in the keychain (shielding of the key with metal objects) – Using an uncoded ignition key – Using an unprogrammed coded ignition key |
– Central Junction Box (CJB), fuse 12 (15 A) – Battery Junction Box (BJB), fuse 9 (20 A) – PCM module – Ignition switch – Loose or corroded connector(s) – PATS transmitter – Starter relay |
3. If an obvious cause for the reported or received complaint is found, correct the fault (if possible) before proceeding to the next step.
4. If the cause of the fault is not obvious, clarify the fault symptom and use FDS 2000 in conjunction with the following Fault Symptom Table and Pinpoint Tests.
