*1 w/o Intuitive Parking Assist System with Smart Key System *2 w/o Intuitive Parking Assist System without Smart Key System *a Front view of wire harness connector
(to Tire Pressure Warning ECU and Receiver) - Measure the resistance according to the value(s) in the table below.
Standard Resistance (w/o Intuitive Parking Assist System with Smart Key System)
Tester Connection Condition Specified Condition O25-9 (CANH) - O25-10 (CANL) Cable disconnected from negative (-) battery terminal 54 to 69 Ω Standard Resistance (w/o Intuitive Parking Assist System without Smart Key System)
Tester Connection Condition Specified Condition O33-9 (CANH) - O33-10 (CANL) Cable disconnected from negative (-) battery terminal 54 to 69 Ω
NG → REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (TIRE PRESSURE WARNING ECU AND RECEIVER)
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.TEXT IN ILLUSTRATION

(to Tire Pressure Warning ECU and Receiver)Standard Resistance (w/o Intuitive Parking Assist System with Smart Key System)
Tester Connection Condition Specified Condition O25-12 (GND) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω Standard Resistance (w/o Intuitive Parking Assist System without Smart Key System)
Tester Connection Condition Specified Condition O33-12 (GND) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω - Reconnect the cable to the negative (-) battery terminal.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage (w/o Intuitive Parking Assist System with Smart Key System)
Tester Connection Condition Specified Condition O25-1 (IG) - Body ground Ignition switch ON 11 to 14 V Standard Voltage (w/o Intuitive Parking Assist System without Smart Key System)
Tester Connection Condition Specified Condition O33-1 (IG) - Body ground Ignition switch ON 11 to 14 V
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
OK → See step 3
- Measure the resistance according to the value(s) in the table below.
- REPLACE TIRE PRESSURE WARNING ECU AND RECEIVER. Refer to REMOVAL [08/2015 - ]
