INSPECTION PROCEDURE
PROCEDURE
|
1. |
INSPECT BRAKE ACTUATOR SOLENOID |
(a) Disconnect the A43 and A45 actuator connectors.
(b) Measure the resistance of the actuator.
Standard resistance:
|
Tester Connection |
Specified Condition |
|---|---|
|
A43-4 (BS) - A45-1 (SRRR) |
2.00 to 2.40 Ω |
|
A43-4 (BS) - A45-2 (SRRH) |
6.95 to 7.45 Ω |
|
A43-4 (BS) - A45-3 (SRLR) |
2.00 to 2.40 Ω |
|
A43-4 (BS) - A45-4 (SRLH) |
6.95 to 7.45 Ω |
|
A43-4 (BS) - A45-7 (SFLR) |
2.00 to 2.40 Ω |
|
A43-4 (BS) - A45-8 (SFLH) |
6.95 to 7.45 Ω |
|
A43-4 (BS) - A45-9 (SFRR) |
2.00 to 2.40 Ω |
|
A43-4 (BS) - A45-10 (SFRH) |
6.95 to 7.45 Ω |
HINT:
Resistance of each solenoid at 20°C (68°F).

2. |
CHECK WIRE HARNESS (SKID CONTROL ECU ASSEMBLY - BRAKE ACTUATOR) |
| NG |
|
| OK |
|
CHECK EACH CONNECTION IF SAME CODE IS STILL OUTPUT AFTER DTC DELETION (IF CONNECTION IS NORMAL, SKID CONTROL ECU MAY BE DEFECTIVE) |
