Inspection Procedure
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT NO. 2 IGNITION RELAY
- Remove the IG2 relay from the No. 2 engine room junction block and relay block.
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
RESISTANCE SPECIFICATIONTester Connection Specified Condition 3 - 5 10 kΩ or higher 3 - 5 Below 1 Ω
(when battery voltage is applied to terminals 1 and 2)
NG: REPLACE NO. 2 IGNITION RELAY
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BODY GROUND)
- Disconnect the J29 connector from the steering lock actuator assembly.
- Measure the resistance according to the value (s) in the table below
Standard Resistance
RESISTANCE SPECIFICATIONTester Connection Condition Specified Condition J29-1 (GND) - Body ground Always Below 1 Ω J29-2 (SGND) - Body ground Always Below 1 Ω
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY BATTERY)
- Measure the voltage according to the value (s) in the table below.
Standard Voltage
VOLTAGE SPECIFICATIONTester Connection Switch Condition Specified Condition J29-6 (IG2) - J29-1 (GND) Engine switch on (IG) 10 to 14 V J29-6 (IG2) - J29-2 (SGND) Engine switch on (IG) 10 to 14 V - Measure the resistance according to the value (s) in the table below

Standard Resistance
RESISTANCE SPECIFICATIONTester Connection Switch Condition Specified Condition (1)J29-6 (IG2) - J29-7 (B) Engine switch off 10 kΩ or higher (1) This measurement is performed with the engine switch off to check for a battery voltage short in the IG2 circuit
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: REPLACE STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) (See DISASSEMBLY )
- Measure the voltage according to the value (s) in the table below.
