Pinpoint Test H: DTC P1699; CHECK THE A/CCM SUPPLIES AND GROUNDS

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Jaguar XKR, 2006 Jaguar XK8, 2005 Jaguar XKR, 2005 Jaguar XK8, and 2004 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.

CHECK THE PERMANENT POWER SUPPLY TO THE A/CCM
Disconnect the A/CCM electrical connector, AC04.

Measure the voltage between AC04, pin 05 (NW) and GROUND.

Is the voltage less than 10 volts?

YES: REPAIR the circuit between the A/CCM and battery. This circuit includes the passenger side fuse box, (fuse 6) and the high power protection module. For additional information, refer to the wiring diagrams. Test the system for normal operation.

NO: Go to step 2.
CHECK THE IGNITION SWITCHED POWER SUPPLY TO THE ASCCM
Turn the ignition switch to the ON position.

Measure the voltage between AC04, pin 01 (WU) and GROUND.

Is the voltage less than 10 volts?

YES: REPAIR the circuit between the A/CCM and battery. This circuit includes the driver side fuse box, (fuse 12) the ignition positive relay and the high power protection module. For additional information, refer to the wiring diagrams. Test the system for normal operation.

NO: Go to step 3.
CHECK THE PERMANENT GROUND TO THE A/CCM
Measure the resistance between AC04, pin 20 (BK) and GROUND.

Is the resistance greater than 5 ohms?

YES: REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Test the system for normal operation.

NO: Go to step 4.
CHECK THE ACCESSORY SWITCHED GROUND TO THE A/CCM
Turn the ignition switch to the ACC position.

Measure the resistance between AC04, pin 03 (WR) and GROUND.

Is the resistance greater than 5 ohms?

YES: REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Test the system for normal operation.

NO: If the CAN tests are satisfactory, contact dealer technical support for advice on possible A/CCM failure.
