INSPECTION PROCEDURE

PROCEDURE

1. CHECK FOR DTCS (DTC P0A1F-123, P0AFC-123 OR P0A95-123 IS OUTPUT)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result

A -- Continue to next step.

2. REPLACE HV BATTERY JUNCTION BLOCK ASSEMBLY

HINT
For the removal and installation procedures related to the HV battery junction block assembly, Removal.

NEXT -- Continue to next step.

3. CLEAR DTC (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.

(d) Clear the DTCs and freeze frame data.

(e) Perform a road test to charge and discharge the HV battery.
