New EL-52641Trailer Presence Simulator Tester

The recently released EL-52641 Trailer Presence Simulator Tester is a trailer module tester and trailer simulator that can be used to simulate a trailer connected to the vehicle when performing trailer signal diagnostics and trailer tire pressure monitor sensor programming.

The EL-52641 Tester includes a simulator module equipped with indicator lights and a 25 ft. cable with a trailer 7-pin connector. (Fig. 8) The long cable makes it easy to conduct and review diagnostic tests from inside the vehicle.

Testing

测试仪具有指示灯，提供关于向拖车的车辆信号提供反馈，用于倒灯，电池电量，右转向信号和制动灯，左转信号和制动灯以及制动控制器输出。使用测试仪在服务信息中更新了几种拖车诊断程序，包括拖车灯故障条件和拖车轮胎压力传感器DTC。

To use the tester for signal testing, simply plug the 7-way connector of the tester into the trailer connector port at the rear of the vehicle. With the vehicle running, verify the 12V circuit is powered or turn on the tail light circuit. Activate each circuit while monitoring the corresponding indicator light on the tester. For example, activate the left turn signal and the LT (left turn signal) indicator light on the tester should illuminate. Or apply the brakes and shift to Reverse and the RL (reverse lights) indicator light and the LT (left turn signal) and RT (right turn signal) indicator lights on the tester should illuminate, showing that the reverse lights and brake lights are working properly.

For vehicles equipped with an Integrated Trailer Brake Controller, a Trailer Connected message should display on the Driver Information Center.

The EL-52641 Tester also can be used to simulate the presence of a trailer in order to learn the trailer tire pressure monitor sensors in a case where the actual trailer is not available.

After plugging the 7-way connector of the tester into the trailer connector port, follow the appropriate Service Information procedure to learn the trailer tire pressure monitor sensors.
