Air Conditioning Amplifier Communication Stop Mode [04/2018 -]: Procedure
- CHECK FOR OPEN IN CAN BUS LINES (AIR CONDITIONING AMPLIFIER ASSEMBLY BRANCH LINE)
- Disconnect the cable from the negative (-) battery terminal.
- Disconnect the G35 air conditioning amplifier assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G35-11 (CANH) - G35-12 (CANL) Cable disconnected from negative (-) battery terminal 54 to 69 Ω *a Front view of wire harness connector
(to Air Conditioning Amplifier Assembly)Result
Result OK NG
Result:
NG
REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (AIR CONDITIONING AMPLIFIER ASSEMBLY)
Result:
OK
See step 2
- 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 G35-4 (GND) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω *a Front view of wire harness connector
(to Air Conditioning Amplifier Assembly) - Reconnect the cable to the negative (-) battery terminal.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition G35-1 (B) - Body ground Always 11 to 14 V G35-2 (IG+) - Body ground Engine switch on (IG) 11 to 14 V Result
Result OK NG
Result:
OK
