Pinpoint Tests AF: Glow Plug System: Introduction
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2019 Ford Transit-350 HD, 2019 Ford Transit-350, 2019 Ford Transit-250, 2019 Ford Transit-150, and 2019 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The wait-to-start indicator ON time is independent from the glow plug control module (GPCM)
NOTE:
Make sure the vehicle batteries are fully charged prior to carrying out the glow plug monitor self-test.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
This pinpoint test is intended to diagnose the following:
- harness circuits: glow plug, CAN2+, CAN2-, ISP-R, PWRGND, VBATT, and VPWR
- glow plugs (12A342)
- GPCM (12B533)
