Warning Light Illumination Pattern

A: INSPECTION

1. Ignition switch
2. OFF
3. ON
4. Engine start
5. Brake warning light (EBD warning light)
6. Light OFF
7. Light ON
8. Approx. 2 seconds
9. If the parking brake is being operated, illumination continues until the brake is released.
10. Electronic parking brake warning light (C6 model only)
11. Hill hold indicator light
12. Parking brake
13. Released

1) When warning lights or indicator lights do not illuminate in accordance with this illumination pattern, there must be an electrical malfunction.

2) When warning lights or indicator lights remain constantly OFF, check the combination meter circuit or CAN communication circuit. <Ref. to PB(diag)- 28, BRAKE WARNING LIGHT, ELECTRONIC PARKING BRAKE WARNING LIGHT AND HILL HOLD INDICATOR LIGHT DO NOT COME ON, Warning Light Illumination Pattern.>

3) When the electronic parking brake warning light (C6 model only) and hill hold indicator light do not go off, check the combination meter circuit, CAN communication circuit and electronic parking brake control module. <Ref. to PB(diag)-30, ELECTRONIC PARKING BRAKE WARNING LIGHT AND HILL HOLD INDICATOR LIGHT DO NOT GO OFF, Warning Light Illumination Pattern.> <Ref. to PB(diag)- 29, HILL HOLD INDICATOR LIGHT DO NOT GO OFF, Warning Light Illumination Pattern.>

4) When the brake warning light does not go off, check the combination meter circuit, CAN communication circuit, electronic parking brake control module, and VDCCM&H/U. <Ref. to PB(diag)-31, BRAKE WARNING LIGHT DOES NOT GO OFF, Warning Light Illumination Pattern.> <Ref. to PB(diag)- 33, BRAKE WARNING LIGHT REMAINS BLINKING, Warning Light Illumination Pattern.>

5) After replacing the electronic parking brake control module, the brake warning light blinks. Make sure to perform the Force Sensor Calibration Mode and Clutch Sensor Calibration Mode. <Ref. to PB(diag)-18, FORCE SENSOR CALIBRATION MODE, OPERATION, Subaru Select Monitor.>

<Ref. to PB(diag)-20, CLUTCH SENSOR CALIBRATION MODE, OPERATION, Subaru Select Monitor.>

6) When operation and release of the parking brake is repeated excessively, the brake warning light blinks and the parking brake switch operation may not be accepted for several tens of seconds; this is not malfunction, however.
