Troubleshooting
Step Action Yes No
1 “EPS” warning light power supply check
1) Turn ignition switch ON.
Do the other warning light come on?
Go to Step 2. “GRN”, “RED/BLK” wire
circuit or circuit fuse for
combination meter is
open or short to ground.
2 Fuse check
1) Turn ignition switch OFF.
2) Remove and inspect circuit fuse for P/S control module.
Is fuse in good condition?
Reinstall fuse, and then
go to Step 3. Check “GRN” wire
circuit for short to
ground.
If OK, replace fuse.
3 P/S control module power supply and ground circuit
check
Check power supply circuit and ground circuit for P/S control
module referring to “P/S Control Module Power Supply and
Ground Circuit Check”.
Is check result in good condition?
Go to Step 4. Repair or replace
defective circuit.
4 Combination meter power supply circuit check
1) Remove combination meter and disconnect combination
meter connector (“G241”) with ignition switch turned
OFF.
2) Check for proper connection to the combination meter at
“G241-31” terminal.
3) If OK, check voltage between “G241-31” (“RED/BLK”
wire) terminal and body ground with ignition switch ON.
Is it 10 – 14 V?
Go to Step 5. “RED/BLK” wire circuit
is open or short to
ground.
5 “EPS” warning light circuit resistance check
1) Check for proper connection to the combination meter at
“G241-25” terminal and P/S control module at “E11-5”
terminal.
2) Check that “EPS warning light circuit” is as follows.
• Insulation resistance of “EPS warning light circuit”
wire is infinity between its terminal and each terminal
at combination meter connector.
• Wiring resistance of “EPS warning light circuit” wire is
less than 1
Ω
.
• Insulation resistance of “EPS warning light circuit”
wire is infinity between its terminal and vehicle body
ground.
Is circuit in good condition?
“GRY” wire circuit is
open. Go to Step 6.
6 “EPS” warning light circuit voltage check
1) Connect combination meter connector (“G241”) with
ignition switch turned OFF.
2) Check for voltage between “E11-5” (“GRY” wire) terminal
and body ground with ignition switch ON.
Is it 10 – 14 V?
Replace the P/S control
module. Replace the
combination meter.
