Power Circuits

Verify that vehicle system voltage is OK (i.e. 9 to 16 volts). If voltage is out of
range, correct system problem. Unplug connector at ECU and turn on ignition
switch. If the voltage on PMV Power is different than system voltage, repair
wiring. Clear trouble codes and verify that the indicator lamp turns out after bulb
check.

Verify that vehicle system voltage is OK (i.e. 9 to 16 volts). If voltage is out of

Verify that vehicle system voltage is OK (i.e. 9 to 16 volts). If voltage is out of
range, correct system problem. Unplug connector at ECU and turn on ignition
switch. If the voltage on PMV Power is different than system voltage, repair
wiring. Clear trouble codes and verify that the indicator lamp turns out after bulb
check.

Unplug connector at ECU and check for continuity to ground on PMV Ground. If
continuity to ground is not present, repair harness.

Verify that vehicle system voltage is OK (i.e. 9 to 16 volts). If voltage is out of
range, correct system problem. Unplug connector at ECU and turn on ignition
switch. If the voltage on pin A-8 is different than system voltage, repair wiring.
Clear trouble codes and verify that the indicator lamp turns out after bulb check.

Verify that vehicle system voltage is OK (i.e. 9 to 16 volts). If voltage is out of
range, correct system problem. Unplug connector at ECU and turn on ignition
switch. If the voltage on PMV Power is different than system voltage, repair
wiring. Clear trouble codes and verify that the indicator lamp turns out after bulb
check.

Verify that vehicle system voltage is OK (i.e. 9 to 18 volts). If voltage is out of
range, correct system problem. Unplug connector at ECU and turn on ignition
switch. If the voltage on one PMV Power pin differs from the other by greater than
0.5 volts, repair wiring. (Check circuit breakers and/or fuses on diagonal supply
line.) Clear trouble codes and verify that the indicator lamp turns out after bulb
check.
