INSPECTION PROCEDURE

NOTICE:

If the transponder key ECU assembly or ECM is replaced, refer to Service Bulletin.
When using the GTS with the vehicle ignition switch off, connect the GTS to the vehicle and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select the Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Immobiliser. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

for LHD
Tester Connection	Condition	Specified Condition
E96-12 (EFII) - A38-29 (IMO)	Always	Below 1 Ω
E96-13 (EFIO) - A38-40 (IMI)	Always	Below 1 Ω
E96-12 (EFII) - Body ground	Always	10 kΩ or higher
E96-13 (EFIO) - Body ground	Always	10 kΩ or higher
A38-29 (IMO) - Body ground	Always	10 kΩ or higher
A38-40 (IMI) - Body ground	Always	10 kΩ or higher

for RHD
Tester Connection	Condition	Specified Condition
E96-12 (EFII) - A52-29 (IMO)	Always	Below 1 Ω
