Pinpoint Test AD: The Intelligent Access (IA) Feature Is Inoperative From A Front Door
Normal Operation
The Remote Function Actuator (RFA) module controls the unlocking and locking of the doors when requested by the Intelligent Access (IA) feature. When the lock or unlock sensor is touched on either front door exterior door handle, the RFA (Remote Function Actuator) module activates the external antenna (located in the front exterior door handles), which sends out a low frequency signal. If an IA (Intelligent Access) key is within 1 m (3 ft) of the front exterior door handle, the low frequency signal activates the IA (Intelligent Access) key. When the IA (Intelligent Access) key is activated, it sends a high frequency signal back to the Tire Pressure Monitor (TPM) module. Once the TPM (Tire Pressure Monitor) module receives the IA (Intelligent Access) key information, it sends it to the RFA (Remote Function Actuator) module. If the RFA (Remote Function Actuator) module determines that it was a programmed IA (Intelligent Access) key, it locks or unlocks the doors.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- External antenna (part of the exterior front door handle)
- Lock/unlock sensors (part of the exterior front door handle)
- IA (Intelligent Access) key
- TPM (Tire Pressure Monitor) module
- RFA (Remote Function Actuator) module
PINPOINT TEST AD : THE IA (Intelligent Access) FEATURE IS INOPERATIVE FROM A FRONT DOOR
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: The IA (Intelligent Access) feature is a programmable parameter and can be enabled/disabled with a scan tool. If the feature is disabled, the Intelligent Access (IA) feature to enter the vehicle and passive starting will be inoperative. To start the vehicle, the IA (Intelligent Access) key has to be placed in the backup slot. for information on enabling/disabling the IA (Intelligent Access) feature.
