CAUTION / NOTICE / HINT

HINT:: ·

Use these procedures to troubleshoot the CXPI communication system.

·

*: Use the GTS.

PROCEDURE

1.VEHICLE BROUGHT TO WORKSHOP

Result:

Proceed to
NEXT

2.INSPECT AUXILIARY BATTERY VOLTAGE

Measure the auxiliary battery voltage.*1

Measure the auxiliary battery voltage with the ignition switch off.*2

*1: for Gasoline Model

*2: for HV Model

Standard voltage:: 11 to 14 V

If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.

Result:
