CAUTION / NOTICE / HINT
NOTICE:
- To ensure that the electric parking brake does not operate, wait for 3 minutes or more with the ignition switch off, the driver door closed, and the brake pedal not depressed, then disconnect each connector, fuse and relay.
-
After replacing the No. 2 skid control ECU (brake actuator assembly), perform "Calibration".

1. |
INSPECT NO. 1 PARKING BRAKE WIRE ASSEMBLY |
(a) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
OK:
The connector is securely connected.
(b) Disconnect the MM4 and M49 No. 1 parking brake wire assembly connectors.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Measure the resistance according to the value(s) in the table below.
