Inspection procedure

Notice:

Hint:

Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.

  1. Check wire harness (ecm - battery and body ground)

  1. Disconnect the a9 and b30 ecm connectors.

Ecm power source circuit
Description When the ignition switch is turned on, the battery voltage is applied to the igsw of the ecm. The output signal from the mrel terminal of the ecm causes a current to flow to the coil, closing the contacts of the integration relay (efi main relay) and supplying power to either term ...

Transmitter id
Description The tire pressure warning valve and transmitter that is installed in the tires and wheels measures the air pressure of the tires. The measured values are transmitted to the tire pressure warning receiver on the body as radio waves and then sent to the tire pressure warning ecu ...

On-vehicle inspection
Check ignition coil assembly and perform spark test Notice: in this section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10 to 50°c (14 to 122°f). "Hot" means approximately 50 to 100°c (122 to 212 ...
