6.20

DESCRIPTION AND OPERATION

ed02980

See Figure 6-42. A feedback voltage signal in the secondary

ignition circuit (terminal B) detects the presence of combustion

each time a cylinder fires on ECM [78-1] terminal 9. For dia-

gnostic purposes, this signal is only analyzed at high speed

and load conditions where it may be easily measured. Failure

to detect combustion at high speed and load means one of

following conditions is true:

•

Cylinder is truly misfiring.

•

There is a lack of continuity in the ignition coil secondary

circuit.

NOTES

Check for non-OE spark plugs and cables before testing.

DESCRIPTION AND OPERATION

ed03355

The active exhaust actuator is included on HDI vehicles only.

The active exhaust actuator system utilizes an actuator valve

located in the rear exhaust pipe which is connected to a servo

motor via a cable. The valve position automatically adjusts to

enhance engine performance.

6.22

DESCRIPTION AND OPERATION

NOTE

The Jiffy Stand Sensor (JSS) uses a Hall-effect sensor to

The ECM supplies 5V reference voltage to the VSS, TPS and

monitor jiffy stand position.

MAP sensors in addition to the JSS. Problems on the 5V refer-

ence will cause other DTCs.

•

When the jiffy stand is fully retracted the sensor picks up

the presence of the metal tab mounted to the jiffy stand.

ed03292

The metal tab is moved away from the sensor as the jiffy

stand is extended.

•

When the jiffy stand is extended the engine will only start

and run if the BCM determines the transmission is in

neutral. This is done by monitoring the neutral switch input

to the BCM and communicating that input over the CAN

bus circuit to the ECM.

See Figure 6-47. The JSS is powered and monitored by the

ECM. The ECM supplies the 5V reference to the JSS. The JSS

sends a signal back to the ECM. This signal is used by the

ECM to determine when the jiffy stand is retracted or extended.

The JSS is grounded through the ECM.

The JSS also has a Fail Enable Mode. This mode allows the

engine to start and run if the system recognizes a problem with

DTC P2300,

P2301, P2303, P2304

6.25

DESCRIPTION AND OPERATION

ed02980

Ignition coil DTCs will set if the ignition coil primary voltage is

out of range. This could occur if there is an open coil or loss

of power to the coil. If front and rear DTCs are set simultan-

eously, it is likely a coil power failure or a coil failure. The coil

receives power from the BCM at the same time the purge

solenoid, active exhaust actuator, active intake solenoid, ECM

and injectors are activated.

Diagnostic Tips

When disconnecting any connectors always inspect connector

for corrosion or backed out terminals and repair as required.

Connector Information

For additional information about the connectors in the following

diagram(s) and diagnostic procedure(s), including the color of

the harness test kit terminal probes, see B.1 CONNECTORS.
