(6) Turn the "CRUISE" (MAIN) switch to the "OFF" position.
(7) Turn the ignition switch to the "LOCK" (OFF) position.
(8) Disconnect special tool MB991923 between the PCM and

the body-side harness connector.

(9) Reconnect all the connectors to the PCM.
Q: Is the measured voltage 0.5 volt or less?

YES : Go to Step 12.
NO : Go to Step 11.

STEP 11. Check PCM connector B-20 for loose, corroded
or damaged terminals, or terminals pushed back in the
connector.
Q: Are the connector and terminals in good condition?

YES : Install the air bag module (driver’s side). (Refer to

GROUP 52B, Air Bag Modules and Clock Spring

P.52B-369

). Then go to Step 17.

NO : Repair or replace the faulty connector. (Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

). Install the air bag module (driver’s side).

(Refer to GROUP 52B, Air Bag Modules and Clock
Spring
