Result Proceed to OK (w/ Stop and Start System) A OK (w/o Stop and Start System) B NG C
Result:
B
See step 3
Result:
C
REPAIR OR REPLACE CAN MAIN WIRE OR CONNECTOR
Result:
A
See step 2
- Disconnect the cable from the negative (-) battery terminal.
- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G18-23 (ES) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω *a Front view of wire harness connector
(to Combination Meter Assembly) - Reconnect the cable to the negative (-) battery terminal.NOTE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
Refer to INITIALIZATION [11/2018 - 02/2019] , or refer to INITIALIZATION [02/2019 - 10/2019] , or refer to INITIALIZATION [10/2019 - 06/2020] , or refer to INITIALIZATION [06/2020 - 08/2020] , or refer to INITIALIZATION [08/2020 - 12/2021] , or refer to INITIALIZATION [12/2021 - 10/2022]
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition G18-22 (B) - Body ground Always 11 to 14 V G18-38 (IG+) - Body ground Ignition switch ON 10.5 to 16 V Ignition switch off Below 1 V Result
Result Proceed to OK A NG (IG+ terminal) B NG (Other terminal) C
Result:
A
REPLACE COMBINATION METER ASSEMBLY
Refer to REMOVAL [11/2018 - 10/2022]
Result:
B
GO TO STOP AND START SYSTEM
