Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found ?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to next procedure.

IG "ON" & ENG "OFF".

Disconnect "PDM RELAY BOX" connector.

Check the voltage between the power of the IG1 connecter in the engine room's fuse box and the vehicles body circuit.

Is voltage within specifications ?

	▶ Go to next procedure.
	▶ Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure. ▶ Check that Fuse IG1-30A is installed or not blown.

Ignition "OFF".

Take off the connects of "the PDM relay box" and "the Smartkey unit (SMK IMMO unit)".

Measure the resistance between the switch of the PDM relay box IG1 and the IG1 circuit of the Smartkey unit. (SMK IMMO unit)

Measure the resistance between the connect coil of the PDM relay box IG1 and the IG1 circuit of the Smartkey unit. (SMK IMMO unit)

Is the measured resistance within specifications ?

	▶ ubstitute with a known-good "SMK IMMO, IG1 Relay" and check for proper operation. If the problem is corrected, replace "SMK IMMO, IG1 Relay" and Go to "verification of vehicle repair" procedure.
	▶ Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure.
