Repair Procedure

Glove Compartment Area





To eliminate a potential rattle noise caused by interference between the E/G and ABS ECUs, attach foam (L: 50 mm, W: 30 mm, T: 5 mm) to the ABS ECU as shown.

To eliminate a potential rattle noise from the junction block connector in the center of the instrument panel, place foam between the junction block case and the connector as shown.
