DTC U0214	Keyless receiver
DETECTION CONDITION	When the keyless receiver power supply voltage is less than 7.5 V
POSSIBLE CAUSE	• Keyless receiver malfunction • Open or short circuit in wiring harness between keyless control module and keyless receiver • Keyless control module malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT WIRING HARNESS BETWEEN KEYLESS RECEIVER AND GROUND • Disconnect keyless receiver connector. • Is there continuity between keyless receiver terminal E and ground?	Yes	Go to next step.
1		No	Repair the wiring harness between the keyless receiver and ground. Go to next step.
2	INSPECT COMMUNICATION CIRCUIT FOR CONTINUITY • Disconnect keyless control module connector and keyless receiver connector. • Inspect the continuity between the following connector terminals. ― Keyless control module: 3A—keyless receiver: A ― Keyless control module: 3C—keyless receiver: C • Is voltage more than 7.5 V?	Yes	Go to next step.
2		No	Repair the wiring harness between the keyless receiver and ground. Go to next step.
3	INSPECT KEYLESS RECEIVER POWER SUPPLY CIRCUIT • Turn the ignition switch to the ON position. • Measure voltage at terminal 3A of keyless control module connector. • Is voltage more than 7.5 V?	Yes	Replace keyless receiver. (See KEYLESS RECEIVER REMOVAL/INSTALLATION.)
3		No	Replace the keyless control module and perform the resetting procedure for the advanced keyless system when replacing the keyless control module. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND START SYSTEM].)
