DESCRIPTION

Short to ground in steering lock unit power supply circuit

DETECTION CONDITION

•  Steering lock unit power supply circuit voltage less than threshold is detected for 0.2 s, while the circuit is active.

POSSIBLE CAUSE

•  Steering lock unit connector or terminals malfunction

•  Keyless control module connector or terminals malfunction

•  Short to ground in wiring harness between steering lock unit terminal F and keyless control module terminal 1C

•  Steering lock unit malfunction

•  Keyless control module malfunction

DESCRIPTION	Short to ground in steering lock unit power supply circuit
DETECTION CONDITION	• Steering lock unit power supply circuit voltage less than threshold is detected for 0.2 s, while the circuit is active.
POSSIBLE CAUSE	• Steering lock unit connector or terminals malfunction • Keyless control module connector or terminals malfunction • Short to ground in wiring harness between steering lock unit terminal F and keyless control module terminal 1C • Steering lock unit malfunction • Keyless control module malfunction

Diagnostic Procedure

Step	Inspection		Action
1	INSPECT STEERING LOCK UNIT CONNECTOR CONDITION • Switch the ignition to off. • Disconnect the negative battery cable. • Disconnect the steering lock unit connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 5.
1		No	Go to the next step.
2	INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION • Disconnect the keyless control module connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 5.
2		No	Go to the next step.
3	INSPECT STEERING LOCK UNIT POWER SUPPLY CIRCUIT FOR SHORT TO GROUND • Steering lock unit and keyless control module connectors are disconnected. • Inspect for continuity between steering lock unit terminal F (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 5.
3		No	Go to the next step.
4	INSPECT STEERING LOCK UNIT • Inspect the steering lock unit. (See STEERING LOCK UNIT INSPECTION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • Is there any malfunction?	Yes	Replace the steering lock unit and perform the steering lock unit programming. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) (See STEERING LOCK UNIT ID CODE REGISTRATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Go to the next step.
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect the disconnected connectors. • Reconnect the negative battery cable. • Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • Switch the ignition to off, then open the door to lock the steering. • Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS. (See DTC INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
5		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
6		No	DTC troubleshooting completed.
