WIRING DIAGRAM
CAUTION / NOTICE / HINT
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
-
Before disconnecting related connectors for inspection, push in on each connector body to check that the connector is not loose or disconnected.
-
When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.
PROCEDURE
1. | CHECK FOR OPEN IN CAN BUS LINES (AIRBAG SENSOR ASSEMBLY BRANCH LINE) |
(a) Disconnect the cable from the negative (-) auxiliary battery terminal.
(b) Disconnect the airbag sensor assembly connector.
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | H14-26 (CAFH) - H14-27 (CAFL) | Cable disconnected from negative (-) auxiliary battery terminal | 54 to 69 Ω | |
| *a | Front view of wire harness connector (to Airbag Sensor Assembly) | | |
NG |
| REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (AIRBAG SENSOR ASSEMBLY) |
OK |
| |
2. | CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT) |
(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | H14-32 (E2) - Body ground | Cable disconnected from negative (-) auxiliary battery terminal | Below 1 Ω | H14-33 (E1) - Body ground | Cable disconnected from negative (-) auxiliary battery terminal | Below 1 Ω | |
| *a | Front view of wire harness connector (to Airbag Sensor Assembly) | | |
(b) Reconnect the cable to the negative (-) auxiliary battery terminal.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
H14-36 (IGR) - Body ground | Ignition switch ON | 11 to 14 V |
OK |
| REPLACE AIRBAG SENSOR ASSEMBLY |
NG |
| REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
