INSPECTION PROCEDURE
PROCEDURE
|
1. |
CHECK BATTERY |
(a) Start the engine.
(b) Check the battery positive voltage.
Standard voltage:
10 to 16 V
| NG |
|
|
|
2. |
CHECK SUSPENSION CONTROL ECU (IG - BODY GROUND) |
|
(a) Remove the suspension control ECU with connectors still connected. |
|
(b) Turn the ignition switch ON.
(c) Measure the voltage between terminal IG of the suspension control ECU and body ground.
Standard voltage:
9 to 14 V
| NG |
|
|
|
3. |
CHECK SUSPENSION CONTROL ECU (GND - BODY GROUND) |
|
(a) Remove the suspension control ECU with connectors still connected. |
|
(b) Measure the resistance between terminal GND of the suspension control ECU and body ground.
Standard resistance:
Below 1Ω
| OK |
|
|
|
4. |
INSPECT FUSE (AHC-IG) |
|
(a) Remove the AHC-IG fuse from the cowl side junction bock LH. |
|
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1Ω
| NG |
|
|
|
5. |
CHECK WIRE HARNESS (SUSPENSION CONTROL ECU - BATTERY) |
| NG |
|
| OK |
|
