Step
3 MIL Power Supply Check
1) Disconnect ignition switch connector.
2) Remove "METER" fuse.
3) Measure resistance between "BLK/YEL"
wire terminal of ignition switch connector
and "BLK/YEL" wire terminal of "METER"
fuse connector.
Is resistance 1 Ω or less?
4 MIL Power Supply Check
1) Connect ignition switch connector.
2) Install "METER" fuse.
3) Remove combination meter referring to
"Combination Meter Removal and Installa-
tion" in Section 8.
4) Check for proper connection to combination
meter connector at "BLU/ORN" wire and
"PPL/WHT" wire terminals.
5) If OK, then turn ignition switch to ON posi-
tion and measure voltage between combi-
nation meter connector at "BLU/ORN" wire
terminal and body ground.
Is it 10 – 14 V?
5 MIL Circuit Check
1) Turn ignition switch OFF position.
2) Disconnect ECM connector "G91".
3) Check for proper connection to ECM con-
nector at "G91-1" wire terminal.
4) Measure resistance between "PPL/WHT"
wire terminal of combination meter connec-
tor and "G91-1" wire terminal of ECM con-
nector.
Is resistance 1 Ω or less?
6 MIL Circuit Check
1) Connect combination meter connectors.
2) Turn ignition switch to ON position.
3) Using service wire, ground "G91-1" terminal
wire of disconnected ECM connector.
Does MIL turn ON?
