Chronology :
11-11-2021: Peterbilt Safety and Compliance reviewed a natural gas truck and found the warning lamp and the warning alarm did not indicate constant warning sound and light when the methane detection system power was lost. Investigation opened.
11-12-2021: 50 trucks are on hold at the plants (48 PB and two (2) KW chassis) and being reworked for creating a redundant power source for warning lamp and buzzer. The field trucks may be reworked similar to the plant rework.
11-19-2021: AELs (KW: 00301N5, PB: 031AHMD) are created as an additional method to identify future trucks with methane detection that may need an alternate design called out.
11-24-2021: Chillicothe confirms rework procedure effectively resolved the concern. Fuse B6 was pulled to simulate a loss of system power, causing the warning lamp to illuminate and alarm to sound.
12-07-2021: Affected population of vehicles in the field defined.
12-09-2021: Warranty Claims checked for this system and found none.
12-22-2021: Safety committee meeting held. The committee agrees that a defect relating to motor vehicle safety exists.

Description of the Cause : The methane detection warning alarm and warning lamp share the same fuse. Absent a redundant power source, the warning lamp and the warning alarm will not operate to produce constant warning sound and light when the methane detection system loses power. Identification of Any Warning that can Occur : A faint small may indicate the presence of excessive levels of methane gas in CNG trucks Involved Components : Component Name 1 : Methane Detection System Component Description : Methane Detection System consists of an assembly of sensors, gauge, warning buzzer and lamp Component Part Number : Assembly does not have part number, but PP607005 is part number for gauge Supplier Identification : Component Manufacturer Name : PACCAR Address : 777 106th Ave. NE Bellevue 98004 Country : NR Chronology : 11-11-2021: Peterbilt Safety and Compliance reviewed a natural gas truck and found the warning lamp and the warning alarm did not indicate constant warning sound and light when the methane detection system power was lost. Investigation opened. 11-12-2021: 50 trucks are on hold at the plants (48 PB and two (2) KW chassis) and being reworked for creating a redundant power source for warning lamp and buzzer. The field trucks may be reworked similar to the plant rework. Part 573 Safety Recall Report 21V-00N Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 11-19-2021: AELs (KW: 00301N5, PB: 031AHMD) are created as an additional method to identify future trucks with methane detection that may need an alternate design called out. 11-24-2021: Chillicothe confirms rework procedure effectively resolved the concern. Fuse B6 was pulled to simulate a loss of system power, causing the warning lamp to illuminate and alarm to sound. 12-07-2021: Affected population of vehicles in the field defined. 12-09-2021: Warranty Claims checked for this system and found none. 12-22-2021: Safety committee meeting held. The committee agrees that a defect relating to motor vehicle safety exists. Description of Remedy : Description of Remedy Program : PACCAR will notify customers and dealers will provide a redundant power source for the warning alarm and light by moving signal for the warning alarm from shared fuse to the battery splice block in the cab harnesses. Owners who incurred costs to obtain a remedy for the problem addressed by the recall in advance of receiving notification may seek reimbursement through the process outlined in the general reimbursement plan on file. How Remedy Component Differs from Recalled Component : In the remedy component, the circuit for alarm and lights are independent of each other, unlike the original shared fuse for both warnings. Identify How/When Recall Condition was Corrected in Production : Short term remedy for trucks at plant involved adding the spare power jumper. Long term correction involved moving signal for the warning alarm from shared fuse to the battery splice block in the cab harnesses.

Description of the Cause : The methane detection warning alarm and warning lamp share the same fuse. Absent a redundant power source, the warning lamp and the warning alarm will not operate to produce constant warning sound and light when the methane detection system loses power. Identification of Any Warning that can Occur : A faint small may indicate the presence of excessive levels of methane gas in CNG trucks Involved Components : Component Name 1 : Methane Detection System Component Description : Methane Detection System consists of an assembly of sensors, gauge, warning buzzer and lamp Component Part Number : Assembly does not have part number, but PP607005 is part number for gauge Supplier Identification : Component Manufacturer Name : PACCAR Address : 777 106th Ave. NE Bellevue 98004 Country : NR Chronology : 11-11-2021: Peterbilt Safety and Compliance reviewed a natural gas truck and found the warning lamp and the warning alarm did not indicate constant warning sound and light when the methane detection system power was lost. Investigation opened. 11-12-2021: 50 trucks are on hold at the plants (48 PB and two (2) KW chassis) and being reworked for creating a redundant power source for warning lamp and buzzer. The field trucks may be reworked similar to the plant rework. Part 573 Safety Recall Report 21V-00N Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 11-19-2021: AELs (KW: 00301N5, PB: 031AHMD) are created as an additional method to identify future trucks with methane detection that may need an alternate design called out. 11-24-2021: Chillicothe confirms rework procedure effectively resolved the concern. Fuse B6 was pulled to simulate a loss of system power, causing the warning lamp to illuminate and alarm to sound. 12-07-2021: Affected population of vehicles in the field defined. 12-09-2021: Warranty Claims checked for this system and found none. 12-22-2021: Safety committee meeting held. The committee agrees that a defect relating to motor vehicle safety exists. Description of Remedy : Description of Remedy Program : PACCAR will notify customers and dealers will provide a redundant power source for the warning alarm and light by moving signal for the warning alarm from shared fuse to the battery splice block in the cab harnesses. Owners who incurred costs to obtain a remedy for the problem addressed by the recall in advance of receiving notification may seek reimbursement through the process outlined in the general reimbursement plan on file. How Remedy Component Differs from Recalled Component : In the remedy component, the circuit for alarm and lights are independent of each other, unlike the original shared fuse for both warnings. Identify How/When Recall Condition was Corrected in Production : Short term remedy for trucks at plant involved adding the spare power jumper. Long term correction involved moving signal for the warning alarm from shared fuse to the battery splice block in the cab harnesses.
