修复本田的P1298 ELD电路电压过高问题

本田汽车配备了电动载荷检测器(ELD)。 ELD向ECM发送信号,ECM控制电压调节器,并调整现场线圈电压以匹配负载。 ELD在低负载期间降低现场线圈电压以提高燃油经济性。

2005年5月6日,本田公司发布了第05-006号服务公告,以解决P1298 ELD电路电压高故障代码的问题。 该服务公告指出,本田公司发现ELD的焊点有问题,建议用更新的零件#38255-S5A-003,H/C 7987571进行更换。

在更换零件之前,进行以下P1298 ELD电路高压测试:

1)复位ECM。 然后启动发动机,打开大灯。 如果ELD电路高电压没有设置,说明问题是间歇性的。

2) 要测试ELD,请断开电气连接器。 然后检查1号端子和地之间的连续性。 如果没有连续性,ELD和地之间就有一个开路。

3) 接下来,检查3号端子和ECM端子D16之间的连续性。 如果没有连续性,检查该线是否开路。

4)启动发动机,让其怠速运转,检查ECM端子A9和D16之间的电压,然后打开大灯。 如果电压没有下降,则更换ELD。 如果电压确实下降,则问题出在ECM。

在这些车辆中,P1298 ELD电路高电压退出:
