|
Go to Step 3.
|
3 |
4WD indicator and/or 4WD low indicator circuit check
1)
Turn ignition switch to OFF position.
2)
Remove combination meter referring to
Combination Meter Removal and Installation
.
3)
Check for proper connection to “G93-12” terminal and/or “G93-16” terminal of combination meter connector.
4)
If OK, then measure resistance the followings.
•
Between “G93-12” terminal of combination meter connector and “E188-24” terminal of 4WD control module connector.
• Between “G93-16” terminal of combination meter connector and “E188-25” terminal of 4WD control module connector.
Is each resistance 1 Ω or less?
|
Substitute a known-good combination meter and recheck.
|
“RED/BLU” and/or “RED/WHT” wire circuit open or high resistance.
|
4 |
Fuse check
1)
Turn ignition switch to OFF position.
Is “METER” fuse in good condition?
|
Go to Step 5.
|
Replace fuse and check for short.
|
5 |
Combination meter power circuit check
1)
Remove combination meter referring to
Combination Meter Removal and Installation
.
2)
Check for proper connection to “G93-21” terminal of combination meter connector.
3)
If OK, then measure voltage between “G93-21” terminal of combination meter connector and vehicle body ground with ignition switch turned ON.
Is voltage 10 – 14 V?
|
Substitute a known-good combination meter and recheck.
|
“BLK/RED” and/or circuit open.
|
6 |
Fuse check
1)
Turn ignition switch to OFF position.
Is “4WD” fuse in good condition?
|
Go to Step 7.
|
Replace fuse and check for short.
|
7 |
4WD control module power circuit check
1)
Check for proper connection to “E188-3” terminal of 4WD control module connector.
2)
If OK, then measure voltage between “E188-3” terminal of 4WD control module connector and vehicle body ground with ignition switch turned ON.
Is voltage 10 – 14 V?
|
Go to Step 8.
|
“YEL/RED” wire circuit open.
|
8 |
4WD control module ground circuit check
1)
Check for proper connection to “E188-10” terminal of 4WD control module connector.
2)
If OK, then measure resistance between “E188-10” terminal of 4WD control module connector and vehicle body ground.
Is it 1 Ω or less?
|
Substitute a known-good 4WD control module and recheck.
|
“BLK” wire circuit open.
