- When replacing the skid control ECU (brake actuator assembly), operate the electric parking brake switch assembly as the parking brake indicator light blinks (red) when the engine switch is first turned on (IG).
PROCEDURE
| 1. | INSPECT NO. 1 PARKING BRAKE WIRE ASSEMBLY |
(a) Turn the engine switch off.
(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
OK:
The connector is securely connected.
(c) Disconnect the bN3 and b1 No. 1 parking brake wire assembly connectors.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the resistance according to the value(s) in the table below.
| *a | Front view of No. 1 Parking Brake Wire Assembly | *b | (to wire harness connector) |
| *c | (to Parking Brake Actuator Assembly RH) | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| bN3-2 or b1-2 (RE+) - Body ground and other terminals | Always | 10 kΩ or higher |
| bN3-1 or b1-1 (RE-) - Body ground and other terminals | Always | 10 kΩ or higher |
| NG | .gif) | REPLACE NO. 1 PARKING BRAKE WIRE ASSEMBLY |
|
| 2. | CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU (BRAKE ACTUATOR ASSEMBLY) - PARKING BRAKE ACTUATOR ASSEMBLY RH) |
(a) Turn the engine switch off.
(b) Make sure the No. 1 parking brake wire assembly is securely installed.
(c) Disconnect the A40 skid control ECU (brake actuator assembly) connector.
(d) Disconnect the b1 parking brake actuator assembly RH connector.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| A40-2 (MRR+) or b1-2 (RE+) - Body ground | Always | 10 kΩ or higher |
| A40-3 (MRR-) or b1-1 (RE-) - Body ground | Always | 10 kΩ or higher |
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
