TSB - No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
NUMBER: 08-007-08 REV. A
GROUP: Electrical
DATE: July 04, 2008
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
MODEL:
2007 - 2008 (JK) Wrangler
NOTE: This bulletin applies to vehicles built on or before May 05, 2008 (MDH 0505XX).
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if equipped, the replacement of the Electric teering Column Lock (ELV). The WCM is also referred to as the Sentry Key Remote Entry Module (SKREEM).
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the remote keyless entry (RKE) system will not operate. This condition may be due to an electrostatic discharge (ESD) from the ignition key into the Wireless Control Module (WCM), causing the WCM to electronically lockup. This condition may occur more frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is more easily produced. This condition is corrected by the replacement of the WCM.
