Pinpoint Test F: DTC B10D7:05

Anti-Theft - With Intelligent Access (IA)

Pinpoint Test F: DTC B10D7:05

Normal Operation

When the Remote Function Actuator (RFA) module enters a key programming state, it activates the Passive Anti-Theft System (PATS) transceiver to read the key placed next to it. The key is programmed into the RFA module memory if a valid Intelligent Access (IA) key is used and there are no concerns with the PATS.

- DTC B10D7:05 ( PATS Key: System Programming Failure) - sets when a IA key is unsuccessfully programmed into the RFA module.

This pinpoint test is intended to diagnose the following:

- IA key
- PATS transceiver

PINPOINT TEST F: DTC B10D7:05

NOTE: At least 2 IA keys must be present prior to carrying out this pinpoint test.

-------------------------------------------------
F1 CHECK THE RFA MODULE DTCs FROM THE SELF-TEST

- Check the recorded results from the RFA module self-test.
- Are any RFA module DTCs retrieved?

Yes
REFER to the RFA DTC Chart. Remote Function Actuator (RFA) Module DTC Chart

No
GO to F2.

-------------------------------------------------
F2 CHECK THE IA KEYS

- Verify the correct IA keys are used with the vehicle. Compare the IA keys with the one shown in Anti-Theft Anti-Theft - Passive Anti-Theft System (PATS) in the Description and Operation information.
- Are the correct keys being used?

Yes
ATTEMPT to program the key again, REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. REPEAT the self-test.

If key programming fails, GO to F3.

No
OBTAIN the correct key(s) for the vehicle. PROGRAM the new key(s). REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. REPEAT the self-test.

-------------------------------------------------
F3 CHECK BOTH IA KEYS

- Program both of the IA keys. Refer to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment.
- Press the START/STOP switch with each IA key in the vehicle at a time.
- Does the ignition turn on with only one key?

Yes
If only one key operates, REPLACE the key that did not program. PROGRAM the new key. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. REPEAT the self-test.

No
If both keys do not program, INSTALL a new PATS transceiver. REFER to Passive Anti-Theft System (PATS) Transceiver Anti-Theft - Passive Anti-Theft System (PATS) - Transceiver. PROGRAM the keys. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. REPEAT the self-test.
