B211E
B211E-IGNITION RUN/ACC/PAD CONTROL CIRCUIT LOWB211E-Ignition Run/Acc/Pad Control Circuit Low:
WHEN MONITORED
With the ignition on.
SET CONDITION
The Front Control Module will set this DTC within 500ms if the (P307) Accessory Delay Relay Control circuit is open or shorted to ground.
POSSIBLE CAUSES
- (P307) accessory delay relay control circuit open
- (P307) accessory delay relay control circuit shorted to ground
- Accessory delay relay
- Front control module
DIAGNOSTIC TEST
1. CHECK FOR ACTIVE DTC
With the scan tool, read the active DTC's.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active DTC's.
Q: Does the scan tool display this DTC as active?
YES: Go To 2
NO: If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
2. ACCESSORY DELAY RELAY
Turn the ignition off.
Install a substitute relay in place of the original Accessory Delay Relay.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active FCM DTC's.
Q: Does the scan tool display this DTC as active?
YES: Go To 3
NO: Replace the original Accessory Delay Relay. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
3. (P307) ACCESSORY DELAY RELAY CONTROL CIRCUIT OPEN
Turn the ignition off.
Remove the FCM from the Power Distribution Module.
Remove the Accessory Delay Relay from the Rear Power Distribution Module.
Measure the resistance of the Accessory Delay Relay Control circuit from the Front Control Module PDM connector to the Relay connector.
Q: Is the resistance below 10.0 ohms?
YES: Go To 4
NO: Repair the Accessory Delay Relay Control circuit for an open. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
4. (P307) ACCESSORY DELAY RELAY CONTROL CIRCUIT SHORTED TO GROUND
Measure the resistance between ground and the (P307) Accessory Delay Relay Control circuit at the relay cavity (85).
Q: Is the resistance below 100.0 ohms?
YES: Repair the (P307) Accessory Delay Relay Control circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Inspect the wiring and connectors for damage or shorted circuits. If ok, replace and program the Front Control Module. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
